Things to Consider When Buying Whitening Mouthwash

Let’s go over the main things that our testers considered when they were choosing the best whitening mouthwashes.

Keeping these aspects in mind can also help you pick out your own favorites for glamorous white teeth as you browse.

1. Ingredients


Ingredients of Mouth Wash

Mouthwash ingredients, of course, directly affect its properties, its taste, feel, and intensity.

They’re arguably the most important single factor.

So, what kinds of ingredients are there?

Hydrogen Peroxide

This common ingredient can be found in just about every bathroom cabinet, but it’s also a vital ingredient of all mouthwash products.

It’s undoubtedly one of the best whitening mouthwash ingredients since it acts as a bleaching agent.

By bleaching your teeth, hydrogen peroxide mouthwash whitening gets rid of stains on the surface of your teeth.

It doesn’t cover your teeth with a false white color but instead brings back the natural bony shade that your teeth would be if they weren’t about in stains.

Some of the best whitening mouthwash products have a lot of hydrogen peroxide.

More hydrogen peroxide mouthwash whitening naturally means faster bleaching and faster stain removal.

So, you should consider a high hydrogen peroxide solution if you’re a man with dark or stained teeth.

However, mouthwashes and other things with hydrogen peroxide are highly acidic, reaching pH levels of around 4 and up.

This means that swishing mouthwash around with a lot of hydrogen peroxide in its formula is a fast way to ruin the enamel of your teeth.

For the best results, you should only use mouthwash with a lot of hydrogen peroxide for the recommended time.

Don’t go overboard and try to use it more frequently to speed up the whitening process.

You may end up causing more harm than good.

Alcohol

Lots of mouthwash products contain some amount of alcohol.

In fact, alcohol is the agent primarily responsible for the burning sensation that most folks associate with the product.

Alcohol is very effective at killing bacteria and sanitizing your mouth; that’s why it’s used as an antiseptic in many medical or healthcare products.

However, alcohol is also a rather harsh compound that can dry your mouth out and exacerbate teeth sensitivity issues.

It doesn’t wear down your enamel, but it can make your teeth sting or hurt if they are already susceptible to those discomforts.

Alcohol is advantageous when it comes to removing tooth stains since it’s so good at eliminating bacteria and reducing plaque buildup.

Lots of teeth whitening mouthwashes will have alcohol as the main ingredient, but we wouldn’t recommend these for men with sensitive mouths.

Besides, alcohol tends to dry your mouth out and lower saliva production.

Therefore, if you’re a man who already struggles with keeping enough moisture in your mouth, you should avoid mouthwashes with alcohol entirely.

A dry mouth can easily lead to halitosis since a mouth without enough saliva is an excellent breeding ground for different bacteria.

In this sense, alcohol can make bad breath worse instead of better.

But it all depends on your natural saliva production.

Overall, alcohol is an ingredient with significant tradeoffs.

Consider your personal oral health and saliva production, and your teeth sensitivity level, before purchasing a mouthwash with alcohol as a key ingredient.

Activated Charcoal

This natural ingredient helps whiten your teeth without causing enamel damage or increasing tooth sensitivity.

In fact, many dentists recommend that you use activated charcoal with your mouthwash if you have sensitive teeth.

Activated charcoal can neutralize harmful bacteria and help remove plaque at the same time.

Fluoride

This common mouthwash ingredient is found in most types of toothpaste and other mouthwash products.

That’s because it’s excellent at getting rid of bacteria and helping your teeth become healthy and durable.

Fluoride has several enamel-enhancing properties, although it can be a bit rough on vulnerable teeth.

Still, a mouthwash that has fluoride is a good bet if you’re looking for a mouthwash product that can be used for both everyday oral hygiene and for whitening your teeth.

If you use a toothpaste that already has a ton of fluoride, however, you should consider getting a mouthwash without it since you’ll already have plenty of fluoride exposure from your paste alone.

This way, you won’t risk making your teeth too sensitive.

Lemon Oil/Natural Ingredients

You might also find natural ingredients like lemon oil or other citrus extracts.

These acidic components are useful for dissolving plaque and stains that have burrowed into the pocketed surfaces of your teeth.

These ingredients are not typically harmful since they aren’t concentrated enough to cause significant damage unless you use the mouthwash too frequently.

These ingredients are also typically useful for sensitive teeth, although your mileage may vary since everyone’s teeth are different.

You should avoid mouthwash products that have a lot of fruit extracts if you have cavities since these issues will likely flare up and become painful upon contact with sugar.

2. Good for Sensitive Teeth?


Mouthwash good for sensitive teeth

The next important factor to keep in mind is whether or not a given mouthwash will also be suitable for use with sensitive teeth.

This is mainly driven by the ingredients included in the formula, most of which we described above.

Many whitening mouthwash products will contain abrasive materials to help scrape away the compounds that cause tooth stains.

These mouthwashes are bad for men with sensitive teeth and should be avoided.

Instead, looking for mouthwashes with natural ingredients or that lack alcohol is the way to go.

You might also discover mouthwashes that have components or ingredients that are rated for sensitive teeth, and which may cause a soothing sensation upon swishing.

These can be particularly nice for men with sensitive gums as well as teeth, or for kids.

3. Effects


Flavor of mouthwash

The effects of your whitening mouthwash affect its value for money.

Some mouthwash products will only be good for whitening your teeth.

This represents a strange position for your daily oral hygiene routines.

For instance, it’s always a good thing to include a daily swishing of mouthwash to help eliminate excess bacteria.

However, if your chosen mouthwash only whitens your teeth and doesn’t do much in the way of bacteria prevention, you might need to use another mouthwash product to help in that arena.

Then you’ll have to decide if you’re using too much mouthwash for the health of your teeth.

Overall, we’d recommend looking for a mouthwash that both whitens and removes bacteria at the same time.

This kills two birds with one stone and makes it much easier to complete each part of your hygiene routine consistently.

If you suffer from extremely stained teeth, you might consider using a whitening toothpaste or another whitening product instead of relying on mouthwash to do the job.

While whitening mouthwash can be effective, it’s designed to alleviate mild stains or prevent you from obtaining real stains in the first place.

4. Amount


Cost and amount of mouthwash

Finally, you should also pay attention to the amount of mouthwash you get for your purchase.

This varies significantly by manufacturer, but you want to make sure that you get your money’s worth when you buy.

Some mouthwashes come in larger containers and are great for guys who need a lot of the stuff or who plan to use it every day.

This is particularly important if you get a mouthwash that also fights bacteria.

A big bottle saves you money in the long run since you’ll be using it every day.

On the other hand, whitening-only bottles are often smaller and are better reserved for guys who are solely using mouthwash for whitening.

There’s no right answer for everyone when it comes to this aspect.

Just pay attention to how many ounces you’re getting per dollar so you can get an idea of how much you’re paying per swish of your chosen product.


10 Best Whitening Mouthwashes of 2019 Reviewed

1. Crest 3D White Mouthwash

Crest 3D White Mouthwash

This mouthwash combines traditional whitening ingredients in innovative ways to make a fast-acting solution.

Specs

Who Is It Best For?

It’s great for men who need fast-acting mouthwash and a lot of it.

Key Features

This whitening mouthwash is one of the fastest acting you can find in any market.

While some of the best teeth whitening mouthwashes take up to two weeks to show results, this bottle can give you whiter teeth in just seven days.

This is mostly due to its high amount of hydrogen peroxide, as it works quickly and thoroughly to lift staining particles out of the pits and indentations of your teeth.

It also has some citric acid, which makes the mouthwash fresh and even more acidic.

There’s no alcohol, so no chance of it drying your mouth out.

It doesn’t have any particularly active antibacterial components, too.

It can whiten your teeth and fresh and your breath thanks to the mint ingredients, but that’s it.

However, our testers wouldn’t really recommend it for men who have sensitive teeth due to the high amount of hydrogen peroxide in the formula.

It’s intense and effective but not particularly gentle on the enamel of your teeth, even if it seems more tolerable since there isn’t any alcohol.

You get 32 ounces for your purchase.

That’s quite a lot of mouthwash considering the low asking price.

Overall, we’d recommend this mouthwash if whitening is your only real concern.

If you need to improve your oral hygiene with a higher-strength mouthwash, you’ll have better luck with another product.

This is a decent all-around mouthwash that can whiten your teeth and help reduce plaque build-up over time.

While it’s not particularly harsh on your mouth, since alcohol isn’t a part of its formula, it’s not particularly suitable for sensitive teeth due to the high concentrations of hydrogen peroxide.

Citric acid is another significant component of its ingredient list.

The citric acid makes the mouthwash feel lighter on the tongue and fresher overall without stinging or burning the way alcohol usually does.

3. Crest 3D White Brilliance Whitening Mouthwash

Crest 3D White Brilliance Whitening Mouthwash

This mouthwash has gentler ingredients to allow sensitive teeth some whitening options.

Specs

Who Is It Best For?

Men with sensitive teeth will find a lot to like here.

Key Features

This mouthwash is another high-quality whitening product from Crest.

It both whitens your teeth and freshens your breath, although it lacks compounds that are good at protecting your teeth from bacteria.

This is solely an aesthetic mouthwash, but in this department, it excels.

Its ingredient formula takes a lot of inspiration from the Crest dedicated whitening strips.

As a result, you can expect whiter teeth in as little as seven days as opposed to the typical 12 or more.

It also lacks alcohol and hydrogen peroxide in its formula, so men with sensitive teeth should be able to use this mouthwash without an issue.

Instead, it uses phosphoric acid as its primary bleaching component.

This is very effective at whitening your teeth, but you should also be careful not to use this wash too much as you might wear away your enamel over time.

The mouthwash also has a minty flavor and some other soothing ingredients to keep the feel of the fluid light and secure in the mouth.

You get a decent amount of the wash for your purchase, and it’s very affordable to boot.

Overall, we’d readily recommend this mouthwash for any man who needs serious whitening done fast.

4. Colgate Optic Whitening Mouthwash

Colgate Optic Whitening Mouthwash

This mouthwash can do it all and comes in an affordable package, to boot.

Specs

Who Is It Best For?

This is a perfect choice for men in need of whitening very quickly, but who also need some antibacterial protection, as well.

Key Features

This whitening mouthwash comes in a pack of three bottles, each with 32 ounces.

That’s plenty for starting a supply that’ll last you for many months to come.

The formula in each bottle is particularly powerful when it comes to whitening and anticavity protection.

Hydrogen peroxide, citric acid, and phosphoric acid all combine to remove stains from the surface of your teeth and break down plaque and hardened bacteria.

It’s one of the most effective anticavity mouthwashes you can find, even ignoring how well it can whiten your teeth over time.

It can also start showing you whitening results in as little as five days.

That’s above and beyond most other whitening mouthwashes in terms of speed.

That being said, all of these powerful ingredients mean that it’ll be a bit harsh on sensitive teeth.

Besides, it’s particularly dangerous when it comes to wearing down your tooth enamel over time, especially if you overuse it.

You should definitely only use this formula for the recommended amount to avoid these side effects.

The mouthwash has a strong mint flavor to freshen your breath and leave your mouth feeling reinvigorated.

Despite the potent ingredients, there’s no alcohol present, so you won’t suffer from severe burning while you swish it around your mouth.

Overall, this is the pick we’d make if you need powerful whitening and cavity defense in the same bottle.

It’s not recommended for sensitive teeth, though, even if it lacks alcohol.

The combined ingredients are simply too harsh for teeth with thin enamel layers.

Hello Oral Care Activated Charcoal Mouthwash

This mouthwash uses natural ingredients to do just as good a job as the other products on our list.

Key Features

This natural mouthwash has some of the most active ingredients you can put into a formula without damaging your teeth over time.

It’s got things like activated charcoal and coconut oil to soothe your mouth while whitening your teeth over time.

It’s not quite as powerful as products that use hydrogen peroxide, but given enough time to catch up, it’ll produce results that are equally as vibrant and enjoyable.

Altogether, this is one of the top products our testers tried out despite its reliance on natural ingredients.

In fact, its success is probably due to its excellent formula.

6. Nu Smile Whitening Mouthwash

Nu Smile Whitening Mouthwash

This unique formula manages to whiten and clean despite its unusual ingredients.

Specs

Who Is It Best For?

It’s great for men who are tired of the same minty flavor in all their mouthwash products.

Key Features

Although this mouthwash has a significant amount of hydrogen peroxide in its formula, it’s not so concentrated as to prevent use with sensitive teeth.

Because of this aspect, this mouthwash is one of the only peroxide-filled solutions that we’d recommend for use with sensitive teeth.

There are also ingredients like citric acid, which freshen your breath and kill bacteria, and sea salt.

The sea salt helps whiten your teeth by neutralizing harmful acids and breaking down the protein barrier of your teeth enough to get rid of staining particles.

It also helps to strengthen your gums, so it’s great for men with gingivitis or similar oral health problems.

The presence of coconut oil soothes your mouth and attacks harmful bacteria.

Both ingredients combined give the mouthwash an odd flavor at first, but it’s a nice change from the typical mint taste that virtually all other mouthwashes have.

The lack of harsher ingredients means that this mouthwash is incredibly easy to use.

Swishing it around for up to a minute is a breeze; it’ll be hard to go back to Listerine after experiencing the freshness provided by this bottle without so much as a single burning sensation.

The bottle is a little expensive comparatively, but you still get 20 ounces with your purchase.

Overall, we’d readily recommend this bottle for men who’d like a mouthwash a bit different from the rest.

It’s still quite capable and satisfying, even if you must buy a replacement more often than some others.

Mountain Falls Alcohol-Free Whitening Mouthwash

This mouthwash doesn’t need a lot of ingredients to do its job well.

Specs

Who Is It Best For?

It’s a good pick for men who need an effective whitening formula without a bunch of sophisticated ingredients.

Key Features

This mouthwash is a simple formula, but it’s very effective.

It only has a handful of ingredients but uses them all to great effect.

Hydrogen peroxide provides a lot of the whitening power here, but there isn’t enough of it in the formula to cause real irritation to men with sensitive teeth.

There’s also citric acid, which helps eliminate lots of bacteria and which freshens your breath.

This combined with the peroxide, however, can irritate your teeth or cause sensitivity issues.

Be careful if you’re prone to that kind of discomfort.

Its whitening capabilities are really great.

While it’s not particularly fast, this mouthwash has one of the best consistencies we’ve seen in a product.

It keeps your teeth white over time and adds a lot of protection from gingivitis and other oral problems.

Because of this, it’s an excellent all-around mouthwash if you also need a product to improve your mouth health.

There’s no alcohol included, so tingling or burning isn’t likely.

A clean mint flavor adds to the freshening experience and gives you great breath immediately after swishing it around for a minute.

You also get a whopping 4 bottles with your purchase.

That’s plenty of mouthwash to last men for months on end without needing to purchase some more.

This natural mouthwash is one of the most soothing you can experience.

Specs

Who Is It Best For?

It’s ideal for men with sensitive teeth or infected gums.

This mouthwash is made only with natural ingredients, including activated charcoal and coconut oil.

Both of these help to whiten your teeth and eliminate bacteria, respectively.

It’s one of the best passive health-improving compounds you can have in a mouthwash.

Then there’s the included Aloe Vera, which dependable your gums and makes the formula easy to swish around.

No alcohol or hydrogen peroxide means that there’s no chance of burning.

A light mint flavor rounds the package out.

This whitens and cleans without irritating sensitive teeth, which is harder to come by than the reverse.

This biggest downside here is that it’s a bit pricey.

You only get one bottle with the purchase, and it’s not a lot compared to the bigger bottles of mouthwash we’ve looked at so far.

But it’s a great pick if you’d like a top-tier whitening mouthwash that can work with sensitive teeth.

9. Listerine Healthy White Vibrant Fluoride Mouth Rinse

Listerine Healthy White Vibrant Fluoride Mouth Rinse

This mouthwash is well-known and powerful, and for a good reason.

Specs

Who Is It Best For?

It’s suitable for men whose teeth can handle the fluoride and alcohol to get the best whitening action around.

Key Features

Everyone knows this household brans.

It’s got all the most potent ingredients in its formula: alcohol, fluoride, hydrogen peroxide.

That makes it a powerhouse in the cavity-fighting department, as well as the whitening arena.

It’s one of the fastest acting and most noticeable whitening mouthwashes around.

Its anti-germ capabilities are particularly noteworthy.

When combined with its exceptional amount of hydrogen peroxide, it can whiten your teeth faster than almost any other mouthwash.

Only dedicated strips really do it more quickly.

Of course, all these plus sides come with some downsides.

For one, the mouthwash has the traditional burn that requires discipline to endure.

Swishing it around for 60 seconds is a bit harder with this wash than with any other we’ve seen so far.

Besides, this mouthwash isn’t good for sensitive teeth.

You’ll experience some stinging if you use this with low enamel.

It’s also a bit pricey since there’s only 1 bottle in the purchase.

All that being said, this is still our top choice for hardcore whitening and cleaning action.

If your teeth can handle it, you might as well stop here and go with Old Faithful Listerine.

10. Bee Naturals Whitening Pre-Brush Oral Rinse

Bee Naturals Whitening Pre-Brush Oral Rinse

This rinse is effective and meant to be used before brushing your teeth at night.

Specs

Who Is It Best For?

It’s a good pick for men who need a gentle mouthwash above all.

Key Features

This mouthwash is made from natural and gentle ingredients.

It’s not likely to irritate your teeth if they’re sensitive, but it also doesn’t have much in the way of antibacterial action.

It does kill germs to some extent, but it isn’t quite so effective at tackling hardened plaque.

But that’s not what we’re after, anyway.

This mouthwash has other ingredients to help it whiten your teeth over time.

In fact, this wash is supposed to be used before you brush your teeth.

It’ll be rubbed into your teeth more effectively this way and slowly work out those pigmented particles as the days go by.

Continued use will result in whiter teeth than before, guaranteed.

The formula also includes some spearmint oil to imbue it with a fresh minty flavor that’s distinct from the artificial tastes that many other types of mouthwash have.

It’s a bit pricey, but the added advantage of getting excellent whitening work with natural ingredients outweighs the cost.

Frequently Asked Questions About Mouthwash

Frequently Asked Questions

Now you’ve at least got an idea about the best mouthwashes for whitening your teeth.

Let’s tackle any lingering questions that might still be holding your attention.

1. How Do Teeth Become Stained?

Your teeth can become stained due to several reasons, and these reasons can overlap to make the problem more challenging to solve.

You might be suffering from extrinsic teeth stains.

These are stains that are only present on the surface of your teeth and are usually deposited from your food or drink.

Pigmented residue from various items you consume build up in the protein that covers each individual tooth’s enamel.

Over time, these color particles build up more and more to change the color of your tooth even though the white enamel is still present any.

Typical causes of extrinsic teeth stains include drinking lots of coffee or tea or by smoking tobacco.

Sugary drinks which have a pigment, like various sodas, can also cause tooth stains.

This is particularly notable since sugary beverages can break down the surface of your teeth and make this process occur more frequently.

Of all the types, extrinsic teeth stains are the type most receptive to whitening mouthwash and whitening toothpaste efforts.

Their issues are low-stakes and relatively easy to clear up, especially if you take your time with it and alter your diet accordingly.

Intrinsic teeth stains are the second type.

These are stains that occur beneath the surface of your tooth enamel.

Pigmented particles eventually break through the exterior of your teeth and accumulate right on top of your tooth enamel, getting past the protein layer we mentioned before.

This requires some breakdown of the tooth surface to occur, so it’s usually accompanied by an animal breakdown or cavities.

Excessive fluoride use can also cause natural teeth stains to become more prominent.

Although they sound more serious, they can still be removed.

These usually require more powerful bleaching products or professional assistance from a dentist.

Whitening strips are much more effective at getting rid of intrinsic teeth stains than whitening toothpaste or mouthwash.

Finally, age-related teeth stains are the third significant type.

These are usually some combination of extrinsic and intrinsic tooth stains, plus the natural discoloration of your core teeth tissue.

These tissues, called dentin, becomes yellow over time, which is why so many old people seem to have more yellow teeth than young people.

Also, your teeth will automatically become a little less durable and more susceptible to both intrinsic and extrinsic stains as you live your life and accumulate minor damage over time.

The enamel that covers your tooth eventually becomes thinner and is lost, which also allows the dentin to show through.

Age-related teeth stains can’t really be solved by whitening mouthwash or any other remedy.

While it’s certainly possible to stave off the effects of age-related teeth stains by using whitening mouthwash or whitening strips, your teeth will eventually become more yellow than you like simply as a result of the aging process.

However, taking good care of your teeth throughout much of your life and avoiding eating or drinking stain-causing foods or drinks can slow down this process.

People who smoke frequently or who drink coffee every day are more likely to have yellow teeth earlier than people who brush their teeth thoroughly and who use a whitening mouthwash.

2. I Want My Teeth to Be Whiter

Everyone has a maximum “whiteness” to their teeth.

Some people have genuinely pearly whites that can dazzle you when they smile.

Others have teeth that can only sort of become white after a lot of treatments.

It’s important to remember that not everyone can achieve perfect bone-white teeth, nor should they want to.

Not everyone’s enamel is precisely the same shade but maintaining your enamel integrity for as long as possible is key to tooth health and avoiding tooth yellowing as you get older.

If you’ve used whitening mouthwash or other products for a long time and still don’t have teeth as white as you like, you shouldn’t continue using progressively stronger and stronger tools.

You might just have off-white teeth when they’re mostly healthy.

That’s okay!

It’s far better to have off-white teeth that are healthy, and which have durable enamel layers than it is to have artificially white teeth with weak enamel.

3. How Does Whitening Mouthwash Work?

Regular mouthwash works by applying sanitizing or bacteria-fighting solution around in your mouth.

This liquid can reach small nooks and crannies where even the most intrepid floss has difficulty reaching.

In this way, mouthwash helps you obtain a cleaner mouth and can help eliminate halitosis symptoms.

Check out our guide to the best mouthwashes for bad breath here.

Most whitening mouthwashes work similarly, but they often have extra ingredients (or more of the same ingredients) that coat the teeth in solution.

These increased concentrations of hydrogen peroxide or other ingredients effectively act as bleaching agents.

They break up cemented clumps of old food or drink particles and bacteria which may have stained the surfaces of your teeth.

Consider coffee stains as an example.

Lots of hydrogen peroxide buries down into the pits of your teeth and eventually forms a bubble, which rises and carries some of the staining material with it.

These mouthwashes usually carry some risk of minor tooth damage if you over-use them, but so do all mouthwashes.

4. Does Whitening Mouthwash Really Work?

Whitening mouthwash is effective for getting rid of mild to moderate tooth stains over a long period.

Since you only use whitening mouthwash once a day for a short period, it’s much less immediately effective than whitening strips.

This aspect also means that whitening mouthwash only produces results after consistent use.

You have to use whitening mouthwash every single day for about 12 weeks to expect serious changes in the color of your teeth.

That’s why this type of product is best used for mild staining instead of serious staining that needs to be taken care of as soon as possible.

Whitening mouthwash is also great for preventing staining from occurring in the first place.

If you’re an avid coffee or tea drinker, using a whitening mouthwash is a smart way to avoid the onset of staining while being able to maintain your dietary habits and enjoy your favorite drinks.

5. Is Whitening Mouthwash Safe?

Whitening mouthwash is as safe as other types of mouthwash so long as you don’t overuse it.

While some of the compounds in any individual formula might be harsh or harmful to your teeth in excess, they are not painful or dangerous by themselves.

Whitening mouthwash shouldn’t be used if your teeth already have deficient enamel unless your dentist clears it for use.

The enamel is the hardest part of your teeth, and it can degrade or break down over time.

Enamel also can’t be recovered or replaced; it’s usually lost as a result of severe tooth deconstruction from poor oral hygiene.

If you have teeth that already have low enamel, using a mouthwash with a lot of hydrogen peroxide, for instance, might exacerbate your current problems and do more harm than good.

Talk to your dentist if you’re unsure.

6. How Long Should You Swish Mouthwash?

The exact time for which you should swish your mouthwash varies by the bottle.

That’s because certain bottles have (or no) alcohol and other ingredients that affect how intense the sensation is and how abrasive it is to the surfaces of your teeth.

In general, whitening mouthwash will typically have you swish the product around in your mouth for between 30 seconds and 90 seconds depending on intensity.

Lots of guys take this as a challenge and will try to swish their mouthwash around for longer than the recommended time to improve their oral health or prove how tough they are.

Take it from our experts and don’t do this.

The recommendation is there not to protect your ego but to protect your teeth.

Swishing your mouthwash for longer than anticipated can lead to adverse health consequences or degrade your teeth over time.

7. How Often Should I Use Mouthwash?

This also varies by the bottle.

Some mouthwashes are intense enough only to be used once per day, and satisfy all the necessary oral essentials, while others are sensitive or gentle enough that being used twice per day is recommended.

You’ll have to read the instructions carefully to see which time limit applies to your chosen product.

Whatever the case, don’t use mouthwash more than what is recommended.

Even if you have extensively stained teeth, do not swish your whitening mouthwash around after every meal to speed up the whitening process.

Whitening mouthwash is a product that produces results from consistent use over a long time.

8. Is Whitening Mouthwash Better Than Whitening Toothpaste or Strips?

Better is a subjective term, and you must keep in mind what whitening mouthwash is designed to do.

Like we said above, it’s not meant for teeth that are already extensively stained. Instead, it’s supposed to help you get rid of mild tooth stains from things like coffee or tea drinking.

It can also help you avoid getting stains in the first place if your teeth aren’t suffering from them already.

Whitening toothpaste is much the same,in addition to providing the most basic oral essentials.

It’s meant to be used every day and can help whiten your teeth over time without causing too much abrasion or risking the enamel of the affected teeth.

Whitening strips are much more intense and carry several potential health risks since they are much more potent and can produce results in a much shorter amount of time.

Whitening strips are essentially a replacement for getting whitening procedures done at the dentist.

While they can help you achieve a dazzling smile, they are limited to being used with teeth that can withstand their effects and more potent ingredients.
