Best Teeth Whitening Treatment for 2019-Expert Guide & Review


There is no great secret to what offers the best teeth whitening treatment. According to the American Dental Association (ADA) and the dentists we talked, hydrogen peroxide and carbamide peroxide are the only things that work. We round out the teeth whitening products that limit their peroxide to the levels recommended by ADA, then have 39 evaluators evaluate their results. Finally, we compared the delivery method: trays, strips or a gel of paint to find four bleaches that outperformed the rest.

How We Chose the Best Teeth Whitening Treatment

Clearly labeled ingredients

For a tooth whitening to be really effective, it must contain hydrogen peroxide or carbamide peroxide as the active ingredient. Only bleach with peroxides can remove both surface stains and deep stains, while other products such as toothpastes only focus on surface stains. If we could not confirm these active ingredients, we left those products on the shelf.

Safe and effective peroxide levels

According to the ADA, “it is known that at concentrations of hydrogen peroxide of 10% or more, the chemical is potentially corrosive to the mucous membranes or the skin, and can cause a burning sensation and tissue damage.” Florida-based dentist Dr. Katia Friedman DDS told us: “[For carbamide peroxide] 30-35% is theoretically equal to approximately 10% hydrogen peroxide”: these numbers are within safe limits for your mouth.

Dr. Paul Amato, DDS, FAGD explained that if he exceeds 10% of hydrogen peroxide or 35% of carbamide peroxide, “then he is getting the professional degree”. So strong bleach products should only be used under the supervision of the dentist. Be careful to completely protect the tissue from your gums with a rubber dam or gel. In any case, you should consult your dentist before using any product to whiten your teeth to make sure you are getting the best for your teeth and gums.

So we reject any product that contains more than 10% hydrogen peroxide or 35% carbamide peroxide, but we also throw out those that did not include any peroxide or were largely dependent on ineffective methods (such as charcoal or sodium bicarbonate).

Whitening results

We recruited 39 participants in a wide range of ages to try our best products. The experiment began with each tester matching the color of their teeth with a professional guide and placing a “before” photo. After using the teeth whitening product for the recommended time, our evaluators took a picture “after”, evaluated their new tone and completed a survey describing the experience.

From these findings, along with the existing ratings of Consumer Reports and beauty sites such as and Men’s Health, we conclude that the higher the peroxide content and the better the contact with the surface ( think of strips on feathers), whiter teeth.

Easy to use

Getting the best results from your teeth whitening treatment also depends on whether you use it consistently: most bleaches require two treatment sessions per day. In that sense, the best teeth whiteners should be comfortable and easy to use so you are less likely to skip treatments.

We immerse ourselves deeply in the differences between strips, gels, pens and trays to discover what methods of whitening fit perfectly into our daily routines. For the most part, the choice of a method is reduced to personal preferences, but all of our evaluators agreed that the trays were out. They were uncomfortable, messy and used strange-tasting gels.

4 Best Teeth Whiteners Reviews 2019

  • Crest 3D White Luxe Glamorous White Whitestrips – Best whitening strips
  • Go Smile Super White Snap Packs – Best gel whitening treatment
  • Crest 3D White Whitestrips Gentle Routine – Best for sensitive teeth
  • Go Smile On the Go Teeth Whitening Pen – Best for touch-ups

1.Crest 3D White Luxe Glamorous White Whitestrips – Best whitening strips

  • ADA-approved
  • Great results
  • Easy application
  • Strips are highly recommended
  • Not the most comfortable
  • Time intensive

This tried and true method is highly recommended and gets results.

Why we chose it

ADA Seal of Acceptance

Glamorous Whitestrips has a hydrogen peroxide content of 9.5% (according to customer service), which our experts recommend. But the product also has an ADA Seal of Acceptance that verifies that it is safe to use and lives up to its marketing claims.

While we know from previous experience that getting a stamp does not mean that a product is the only one that meets ADA standards; companies must apply and the ADA is not always transparent about the application process; The seal is a valuable sign of quality. That removes the doubt in a world of incomplete whitening claims.

Great results

As for real whitening, the Glamorous Whitestrips did not disappoint. Our testers noticed an average improvement of 1.5 shades in 20 days, and the teeth of our testers were already quite white to begin with.

But because each person’s teeth are different, we wanted to check back and see what others said about Glamorous White. A base of avid fans, plus a 4-star rating on 3,100 Amazon reviews, and praise from the multiple dentists we spoke with helped show that results over 1.5 shades with Glamorous Whitestrips are common.

Easy application

Crest Glamorous White replaces our previous selection of strips, Crest Professional Effects, with a better overall design. The Glamorous strip for the lower teeth has a contoured shape that makes it easier to apply and more comfortable for the required 30 minutes.

Professional Effects uses a rectangular bar that does not fit so easily. The teeth whitening strips are sensitive to the technique, and our tester appreciated the curved design, which molded more naturally to your teeth.

Strips are highly recommended

Although the strips in general can be a little uncomfortable and you have to be careful when applying them to avoid gums, many dentists recommend this method of application since prolonged contact with the teeth can produce better results.

Dr. Friedman explained that “The feathers and gels are the least effective because the peroxide has minimal contact with the teeth. The strips do the work by sticking directly to the teeth and directly applying the peroxide over time.

Points to consider

Not the most comfortable

Like all the strips, there will be some discomfort when using them: it is impossible to ignore that the strips are stuck to the teeth for 30 minutes. But of all the strips we tried, the Glamorous Whitestrips were some of the most comfortable and least sticky.

Time intensive

To get the best results, you must use Glamorous Whitestrips for 30 minutes at a time, which requires a lot of time. To be fair, the results with Glamorous White should last up to six months, which means you can get away with this whitening regimen only twice a year, but for those who have tighter schedules, pressure snap packs Go Smile are faster.

2.Go Smile Super White Snap Packs – Best gel whitening treatment

  • Easy to use
  • Safe for your teeth
  • Impressive results
  • Without a tray or strip, the product is easily diluted
  • Not the most portable

Speedy results from a paint-on application that’s less messy than strips or trays.

Why we chose it

Easy to use

The ease of use really distinguishes Go Smile from the rest. You can apply the gel quickly and it is fully wearable. Just take out a bottle, close it with your fingers to release the solution and paint it on the teeth. We liked the painting approach, because it meant that we could adjust more the placement of the bleach on our teeth and find the best ways to prevent it from getting on our gums. It is much easier to control than single-size strips, which can be difficult to manipulate instead.

In addition, with only about five minutes per treatment, it was perfectly integrated into our daily routine, which was a great advantage. One tester commented: “It was super easy to apply after brushing my teeth. It was an easy habit to form. “

Safe peroxide levels

Although Go Smile will not reveal the exact percentage of peroxide it uses (which, by the way, we do not love), the company confirmed that it is not more than 7% hydrogen peroxide.

Our evaluators also reported no burning sensation in the gums and just as the sensitivity was minimal. In short, Go Smile makes it easy to do it, but with brighter teeth.

Impressive results

Go Smile Snap White Super Packages, which come with 14 treatments for an application twice a day, promise complete results in just one week and bleached the teens from our testers an average of three tones at that time. Quite fast, considering the average time until the full results of the products we tested were 13 days.

Points to consider

Low contact time

However, instant packages are not impeccable. Dentist Nancy Gill, a Colorado-based dentist, DDS told us that the paint approach, such as that used by instant packs, leaves the bleaching solution open to moisture, which “dilutes it and makes it less effective.” , closing the mouth will wash some of the bleach. That said, Go Smile still produced some of the most impressive results during our tests.

Not the most portable

Because the release of the gel requires you to “close” the bottles with a little pressure, they are also not the best to get them moving, you will run a high risk of accidentally bleaching the inside of your bag. To whiten while traveling, the more flexible Crest 3D Whitestrips or a whitening pen with a lid is the way to go.

Crest 3D White Whitestrips Gentle Routine – Best for sensitive teeth

  • Great for sensitive teeth
  • 5-minute treatment
  • Strips are highly recommended
  • Slow results
  • Not as easy to apply

Lower peroxide levels and a shorter wear time keep teeth and gums comfy.

Why we chose it

Designed for sensitive teeth

The sensitivity of the teeth is highly subjective from one person to another. But if your pearly whites are prone to pain, do you avoid ice water? – We suggest Crest 3D White Whitestrips Gentle Routine. The strips have a lower and smoother concentration of hydrogen peroxide (5.25%, depending on customer service) and require only five minutes of use per day compared to 30. None of our testers experienced sensitivity during the four-day trial period. weeks, all reported some level of whitening and an appreciation for the least time commitment.

Lower time commitment

The five minute usage time obtained high ratings from our evaluators. “I put them on every night before I started my bedtime routine,” one tester explained. “When I finished washing my face and applying the moisturizer, I was able to remove the straps and lie down. Easy! “Consistency in use is essential for any method of tooth whitening, and we liked that the Crest Gentle Routine strips were easy to adapt to our routines.

Strips are the most effective

As the name implies, the Crest Gentle routine brush strokes are strips that are applied to the teeth. The dentists we consulted agreed that the strips were the most likely to provide the best results: the strips keep the whitening gel in contact with the teeth. Other methods, such as gels or pens, can leave whitening solutions open to moisture and dilution, which can decrease overall results.

Points to consider

Slower results

While Crest Gentle Routine strips are excellent for sensitive teeth, the lower level of peroxide means that it also takes longer to see the full results (28 days compared to the 20 days of Glamorous White), something that must be taken into account if you are bleaching for an upcoming event. In addition, the experts we consulted, our evaluators and the findings of beauty sites such as and Men’s Health agreed that the higher the peroxide content, the better the final results.

Rectangular strips aren’t as practical

We were not impressed by the Crest Gentle Routine rectangular strips for the lower teeth. These do not naturally conform to your teeth, so you will have to take a little extra care when applying them to avoid gums and get full coverage of your teeth. They are still quite easy to apply, but we missed the curved design offered by others. Strips like Crest Glamorous White Whitestrips.

Go Smile On the Go Teeth Whitening Pen – Best for touch-ups

  • Quick application
  • Ideal for touch-ups on the go
  • Good for sensitive teeth
  • Weakest whitening method
  • Portion control

Not the best for deep whitening, but great for touch-ups in less than a minute.

Why we chose it

Quick application

Whitening pens bring out the skeptic in all of us, but our evaluators agreed that this pen made retouching a breeze. The Go Smile pen takes only a few seconds to stick on the front teeth, although it is recommended that you avoid eating or drinking for at least 20 minutes after application. “All you have to do is turn the lid until the product covers the brush and then paint the product in problematic places,” said one of our evaluators.

Ideal for touch-ups on the go

The Go Smile pen is so discreet that you can whiten it anywhere: in the office bathroom, on a short break or just before an appointment. With its slim, compact design and lower active ingredient content, this pen is actually designed more for retouching than a full bleaching regime.

According to GoSmile customer service, this pen is made with no more than 7% hydrogen peroxide. This means that it may not offer the potentially drastic results of products with a more active ingredient and longer application times, but it is also safe to use when necessary for retouching when you are away from home.

Good for sensitive teeth

Our Go Smile ballpoint testers did not report any of the sensitivity problems that arose with other bleaching pens, such as mild pain and stinging after application. While the sensitivity during whitening will vary from one person to another, like the results of whitening, we prefer the Go Smile because it did not cause any unpleasant side effects during the test.

Points to consider

Weakest method

When it comes to whitening, a higher peroxide content and a longer contact time with the teeth provide better results. As expected, the low contact time of the pens means that they are not the most powerful bleaches, so we recommend the Go Smile pen as a complement to your whitening regime. In other words, the Go Smile pen is not the best option for a deeper whitening, but it is a useful companion for any of our other selections.

Portion control

Our evaluators agreed that it was difficult to say how much they were using and how much was left in the pen, since the plastic housing is not clear. Because the gel itself is clear and relatively tasteless, it may be difficult to know if you are using enough product to cover your teeth or if you are spreading it evenly. But be careful, even the application should prevent this from being too big a problem.

Guide to Teeth Whitening Treatment

How to (safely) get whiter teeth

Consider your dental habits

Consistency is key when it comes to teeth whiteners, so you’ll want to choose the method that best suits your lifestyle. If the 30 minute use time of the Crest Glamorous Whitestrips is hard to fit in your schedule, choosing the faster Go Smile engagement packages or the soft routine strips may be a better option. At the end of the day, using the whitening product that you will use consistently will always give the best results.

Take your dental history into account

Not all teeth can be bleached with over-the-counter products; This is especially true for patients with many fillings, crowns or very dark spots. Color also matters. Patients with yellow teeth (a natural result of aging) generally respond better to teeth whitening products than those with gray teeth (most cases are caused by smoking and taking certain medications, such as tetracycline).

As for the veneers, these generally cannot be bleached and must be replaced. Go Smile states that its products are safe for surfaces of artificial teeth and orthopedic appliances, but the product will not make these veneers whiter than their original color.

Age is also a factor. “Remember that young teeth whiten much better than older teeth,” says Dr. Amato. “Over-the-counter products can work as well as dental products for people aged 16 to 24 because they have not drunk so much coffee or red wine to stain their teeth, unlike adults.”

Consult your dentist

Before spending a single dollar on a bleaching product, we recommend that you visit your dentist to find out if it is suitable for over-the-counter teeth whitening. Dr. Ben Lawlor explained that “sometimes you just need a good cleaning, and only yellow plaque can make your teeth look discolored.”

Consider other teeth whitening methods

If you are not sure about trying peroxide-based tooth whitening, you can begin the process by starting with the basics, such as limiting the exposure of teeth to stain-causing substances and improving your dental hygiene in general.

Brush and floss regularly

The American Dental Association recommends brushing twice a day with fluoride toothpaste. The daily use of dental floss also eliminates the plaque that makes your teeth look darker.

Natural teeth whitening methods

You can definitely try some of these, although there is not much science to support their effectiveness to whiten your teeth.

  • Oil pulling: the coconut oil in your mouth can help fight gingivitis and bad breath, but no study says it actually whitens teeth
  • Baking soda: there is some research that supports the ability of baking soda to whiten teeth when they are present in toothpaste. However, Dr. Philip Fisher, of North Carolina, recommends avoiding these types of toothpaste altogether: “I frown at some of the more abrasive whitening toothpaste, such as baking soda. Try not to use them, because they are harmful to the enamel [and] cause too much sensitivity. “
  • Charcoal: when heated (or activated) and present in toothpaste, charcoal can help absorb stains from the surface of the teeth. However, there are no studies that support this method to remove deeper spots.
  • Apple cider vinegar: has a lot of health benefits and can be used to help fight bacteria, but when used too often, apple cider vinegar can erode the enamel.

Watch for foods that enhance oral health — and those that don’t

You are probably aware that some of your favorite snacks or drinks can have a negative impact on your teeth. Therefore, if you are in the market for whiter teeth, it is a good idea to control your consumption of certain foods and beverages. Some, such as citrus fruits, coffee, and sugary foods and drinks, Whiten enamel, stain teeth or irritate gums. High-fiber foods and green beans, on the other hand, help combat these properties that affect your teeth, while common dairy products like milk and cheese help replace calcium and other lost minerals.

Don’t bother with whitening lights

Some professional and over-the-counter products include a hand-held LED light or a laser that aims to accelerate the tooth whitening process. In most cases, this is a bunk. According to the ADA, “most studies have not reported additional long-term benefits with light-activated systems.” It will not damage your teeth when using an LED light, but it is probably a waste of time and money. Skip it

Teething Whitening FAQ

How often should I whiten my teeth?

The general recommendation is to use over-the-counter whitening products up to twice a year. The use of bleaching products too often can lead to increased tooth sensitivity or white spots; This is natural and is due to certain areas of the teeth that lack calcium (also known as hypocalcification). Excessive whitening can make spots more prominent.

What are some other teeth whitening tips?

The best way to preserve whitening results is to avoid products that cause stains, such as coffee, red wine and dark tails. If skipping coffee in the morning is too difficult, remember to avoid brushing your teeth or using bleach right after, as it can do more harm than good. Acidic foods and drinks soften your teeth, and Dr. Sanda Moldovan, DDS recommended, bathe with water “to diminish the stains and prevent the demineralization of the teeth that causes sensitivity”.

Is there a way decrease tooth sensitivity?

To reduce sensitivity during the whitening process, you can try brushing with Sensodyne Pronamel toothpaste (recommended by some dentists). Dr. Lawlor also recommends “putting some toothpaste on a mouth guard and using it for about an hour after bleaching – seal the sensitive channels that teeth whiteners open to remove stains.” a break! You can always re-whiten later or consult a dentist to see what other options are available.

What about whitening toothpaste or mouthwash?

In short, the whitening of toothpastes and mouth rinses can not eliminate deep stains, as well as whitening treatments. Each of your teeth is made up of multiple layers. First, a layer of enamel offers defense for the crowns of your teeth, the part that exists above the line of the gum. But over time, the things you eat and drink (berries, red wine, coffee) form another layer, the film layer, on your enamel.

Over the years, the film layer may begin to penetrate the porous enamel layer. In other words, the stains of their morning coffee seep into the enamel and establish their permanent residence. No amount of washing or rinsing at the surface level can remove these stains once they have penetrated the enamel layer. Enter: teeth whiteners with whitening chemicals, or peroxides. These can penetrate the tooth enamel and initiate a chemical reaction that breaks up the staining compounds.

Does the FDA regulate teeth whitening products?

The FDA exercises some supervision over cosmetics (over-the-counter teeth whiteners belong to this category): the products can not be “adulterated”, “mislabelled” or use non-approved color additives. However, cosmetics do not have to receive the seal of approval from the FDA before they reach the shelves, which means that labels are not evaluated.

There has been some conversation about whether the FDA should regulate tooth whitening products to bring more clarity to the industry and help prevent frequent and potentially harmful misuse. Some members of the ADA even filed a citizen petition, claiming that unregulated teeth whitening products have the potential to damage teeth and gums.

But the FDA was reluctant to reclassify the products as medicines, stating that there was not enough data to show if the bleaches met the actual definition of a drug and caused “significant adverse effects.”
