Best Whitening Toothpastes 1

Teeth whitening toothpaste tend to whiten teeth in one or two shades and only work on external teeth stains and surface stains. However, they can also be too abrasive, causing more harm than good in the long run.2,4,5,7

The whitening effects of toothpaste are limited due to:6

  • The negligible amount of peroxide in toothpaste
  • The product’s limited contact time with the teeth

NewMouth only recommends whitening toothpaste to supplement other teeth whitening treatments like whitening kits and in-office treatments. This recommendation comes from considering factors like:

  • Whitening toothpaste’s limited effects
  • The formulation of ingredients
  • The side effects of whitening toothpaste
  • Dentists’ recommendations

Whitening kits and in-office treatments provide better and longer-lasting results. Whitening toothpaste is more effective in maintaining the results from these treatments.

What Is an RDA?

Relative Dentin Abrasivity (RDA) is an index used to determine the relative abrasiveness of toothpaste. High RDA values can damage teeth and cause erosion, while low RDA values are less damaging.

According to the American Dental Association, all dentifrices with the ADA Seal of Acceptance must have an RDA of 250 or less. You should avoid toothpastes with an RDA value above 250 since it causes significant enamel damage.

According to customer reviews, Boka offers excellent results for sensitive teeth. However, some find the taste too sweet, especially if they’ve reduced their sugar intake.

Key Ingredients in Whitening Toothpaste

According to Dr. Khushbu Gopalakrishnan, one of New Mouth’s in-house dentists, most whitening toothpaste work through abrasives and/or peroxides.

The peroxide ingredient is usually hydrogen peroxide or carbamide peroxide. They’re bleaching agents that chemically break down and remove stains.

On the other hand, the abrasive ingredients in whitening toothpastes mechanically remove stains. Common ones include:

  • Silica derivatives
  • Charcoal
  • Baking soda

Are Peroxides in Toothpaste Effective?

The peroxide content in whitening toothpastes is negligible, so it won’t matter significantly if they have this ingredient.6 Dr. Khushbu also said that, aside from the low concentration of peroxides, the contact time between toothpaste and teeth is too short to be able to give drastic results.

Are All Whitening Toothpastes the Same?

Most kinds of toothpaste have the same primary components. Although, according to Dr. Khushbu, the specific concentration and agent may vary.

The base components include:10

  • Fluoride — to help prevent cavities
  • Foaming agents — that spread toothpaste throughout the mouth and act as a surfactant
  • Binders — to prevent the separation of powder and liquid ingredients
  • Humectants — to prevent toothpaste from hardening in the tube
  • Solvents — to dissolve ingredients and allow them to be mixed (water is most common)
  • Flavoring agents — get rid of the unpleasant smell and taste of other raw materials and give a cold, refreshing taste
  • Coloring agents — to give toothpaste an attractive appearance
  • Preservatives — to prevent the growth of micro-organisms
  • Pharmaceutical agents — to give the toothpaste additional uses (reduce bad breath, remove teeth stains and plaque, etc.)

Brands will often differ in their concentration and kinds of whitening agents. Some formulations can be too abrasive, causing unwanted side effects.

Side Effects of Whitening Toothpaste

The side effects of whitening toothpaste include:2,4,5,7

  • Gum irritation due to peroxide content
  • Weakened teeth enamel due to abrasives
  • Demineralization

Demineralization is the early stage of tooth decay, and it occurs when the teeth’s enamel wears away. It results in weakened and more sensitive teeth, making a person more prone to dental caries, discomfort, and pain.14

You should also consult a cosmetic dentist to know whether your teeth can handle peroxide-whitening toothpaste. 

Can You Reverse the Side Effects of Whitening Toothpaste?

Remineralization can reverse demineralization to a certain extent. It’s a naturally occurring process in teeth and bone.

Remineralization happens with the help of a few factors, including:15

  • Saliva
  • Fluoride therapy
  • Reduced intake of carbonated, sugary drinks
  • Probiotic bacteria

Saliva is one of the essential biological tools against demineralization, neutralizing the effects of acid exposure. It also provides calcium and phosphate, which maintain the supersaturation of necessary tooth minerals.

Probiotic bacteria are naturally present in the body, but you can also get them from dairy products and supplements. A study suggests that they displace the bacteria that contribute to demineralization.15

How to Pick the Best Whitening Toothpaste

Choosing the best whitening toothpaste relies on following dentists’ recommendations and knowing a toothpaste’s relative dentin abrasivity (RDA) value.3

Here’s what you must consider when choosing a teeth-whitening toothpaste:


Whitening toothpaste will have various ingredients that help you achieve a brighter smile. Some ingredients you should look for in whitening toothpaste are peroxides like carbamide and hydrogen peroxide.

Mild abrasives like calcium or magnesium carbonate can also help remove surface stains. Choosing toothpaste with these ingredients can help you get the most out of your teeth whitening routine.


When you have sensitive teeth, you want to choose teeth whitening toothpastes that are gentle on your teeth. Some kinds of toothpaste have potassium nitrate or strontium chloride, which help reduce sensitivity. 

Dentist’s Recommendations

Some dentists prefer recommending the simplest and most affordable toothpaste from trusted brands, regardless of whether they claim to be teeth-whitening.

There isn’t much difference between recommending a standard toothpaste or a whitening one when it comes to teeth whitening. According to Dr. Khushbu, the ingredients would likely be comparable.

In some cases, dentists may recommend products based on specific needs. For example, if a patient is at a higher risk of developing cavities, Dr. Khushbu would recommend high-fluoride toothpaste.

Relative Dentin Abrasivity (RDA) Value

An RDA value measures the erosive effect of toothpaste ingredients. The score ranges from 4 to 250.

Any reputable brand’s toothpaste with an RDA value of 4 to 70 is considered the best because it isn’t abrasive enough to cause side effects.

The chart includes all kinds of toothpaste from reputable brands, including whitening and non-whitening. You can refer to it here:

Toothpastes with an RDA value of 101 to 250 can harm tooth enamel. Those with an RDA value of 78 to 100 are moderately risky.

How to Prevent Side Effects from Whitening Toothpaste

You can prevent unwanted side effects from whitening toothpastes by doing the following:

  • Follow dentists’ recommendations
  • Know a toothpaste’s RDA value
  • Be more selective with the kind of toothbrush you use

A study found that, even when paired with highly abrasive toothpaste, manual toothbrushes are not as abrasive as electric toothbrushes.11 However, the specific RDA values of manual and electric toothbrushes have not yet been determined.

Theoretically, electric toothbrushes have a teeth-whitening effect because of their abrasiveness. It’s best to pair it with toothpastes having RDA values between 4 and 70.

How to Maintain Teeth Without Whitening Products

If you can’t or don’t want to use whitening kits or get professional teeth-whitening treatments, there are other ways to maintain a bright smile.

Here are some practices you can do to maintain a bright smile without whitening products:

  • Rinse or brush your teeth after eating or drinking food that stains (e.g., coffee, tea, red wine)
  • Use a straw when drinking beverages that stain teeth
  • Practice good oral hygiene (brushing and flossing your teeth twice a day)


Whitening toothpastes have limited effects. Most dentists recommend the simplest and most accessible toothpaste, regardless of their whitening effects.

Whitening kits and in-office treatments are more effective, giving longer-lasting results. Whitening toothpastes are best to maintain the results from these treatments.

Depending on the formulation, some whitening toothpastes can be too abrasive, causing demineralization. You can prevent this by choosing toothpaste with an RDA value of 4 to 70.
