Is Whitening Toothpaste Bad For Your Teeth?

Updated: May 7

Teeth whitening makes your teeth really sensitive and you're not suppose to use it everyday but is that the same for whitening toothpaste? Can you use whitening toothpaste everyday without it harming or damaging your enamel?

Is it safe to be use whitening toothpaste everyday?

It is totally safe to be using whitening toothpaste everyday because most of them don't actually have any whitening ingredients within them! If there is no whitening material in the toothpaste then it can't damage your teeth. Was that a surprise to you?


As a reminder, there are only two ingredients that will whiten your teeth:

  • Hydrogen peroxide

  • Carbamide peroxide

Therefore, if neither of these two ingredients are on the toothpaste packaging, then the chances of it "whitening" your teeth would be pretty slim. We can compare some of the common whitening toothpastes and what is in the box labeled ingredients.


Colgate Total Whitening ingredients:

  • Active ingredients - Stannous Fluoride 0.454%

  • Inactive ingredients - Water, Sorbitol, Hydrated Silica, Glycerin, PEG-12, Tetrasodium Pyrophosphate, Sodium Lauryl Sulfate, Flavor, Microcrystalline Cellulose, Sodium Citrate, Zinc Phosphate, Cellulose gum, Sodium SacDoes whitening toothpaste damage your enamel?

charin, Cocamidopropyl Betaine, Propylene Glycol, Xanthan Gum, Citric Acid, Sucralose, Titanium Dioxide.

Sensodyne Extra Whitening Toothpaste ingredients:

  • Active ingredients - Potassium nitrate, sodium fluoride

  • Inactive ingredients - Water, hydrated silica, sorbitol, glycerin, pentasodium triphosphate, PEG-8, flavor, titanium dioxide, sodium methyl cocoyl taurate, cocamidopropyl betaine, xanthan gum, sodium hydroxide, sodium saccharin, sucralose

You can double check but neither hydrogen peroxide nor carbamide peroxide are listed in there so they don't technically have any whitening properties in the traditional sense. Even the baking soda with peroxide toothpastes don't have it either. This makes it safe to use whitening toothpaste everyday.



Does whitening toothpaste damage your enamel?

Since there is no whitening material in the toothpaste, it will not damage your enamel BUT a different ingredient within it can. Whitening toothpaste can damage your enamel due to the abrasiveness of the toothpaste rather than from the whitening ingredient. That is in fact how they work, by abrading away surface stains on your teeth so that they appear whiter.


According to the American Dental Association (ADA), all toothpastes have an RDA value, relative dentin abrasivity.

  • All toothpastes that are below a 250 RDA value are considered safe for the enamel.

  • All toothpastes that are above 250 RDA may cause harm to your enamel.

Here is a chart of some common toothpastes and their relative dentin abrasivity:

According to the ADA, long term use of a high RDA toothpaste will wear away at the enamel and the dentin so please stay away from those! Also do not forget that your brushing technique also has a correlation with damaging your enamel.

Aggressive brushing with a hard brush will damage your enamel and cause receding gums.



The only whitening toothpaste that works.

Despite the lack of whitening material in most toothpastes, there is actually one toothpaste on the market that does contain it. The only toothpaste with real whitening in it is the Colgate Optic White toothpaste.


The optic white toothpaste contains 3% hydrogen peroxide so it can potentially whiten your teeth. Please be aware that most take home whitening products usually contain 10% or more so the concentration of whitening material is quite low in this paste.


Our theory is that they created the toothpaste with a low concentration so that it is fit for everyday use. A high whitening concentration toothpaste that is used everyday will damage your enamel but a low concentration one will not.



Take away

Most whitening toothpastes are safe for your teeth and enamel because there is no whitening in it. You do have to be cautious because these toothpastes work by abrading surface stains from your teeth to appear whiter. The recommendation by the ADA is to use a toothpaste with a lower RDA value so that it does not damage your enamel.


With that being said, there is one exception due to the one singular toothpaste on the market that contains 3% hydrogen peroxide, the colgate optic white. That one will whiten your teeth!
