Hydrogen or Carbamide Peroxide Whitening? Find out what this means for your teeth.

Updated: Dec 17, 2021







Whitening products differ between which active ingredient they contain as the main whitening solution. Hydrogen peroxide and carbamide peroxide are the two active ingredients in the whitening process. The main difference between hydrogen peroxide and carbamide peroxide is that hydrogen peroxide is an effective whitening agent by itself. On the other hand, carbamide peroxide contains hydrogen peroxide in it. For every 30% of carbamide peroxide, there is also 10% of hydrogen peroxide.


“The main difference between hydrogen peroxide and carbamide peroxide is that hydrogen peroxide is an effective whitening agent by itself. ”

A journal published by American Dental Association showed that while carbamide peroxide shows slightly more dramatic results at first, products containing both ingredients produce exactly the same results. Hydrogen peroxide breaks down faster than carbamide peroxide and releases most of its whitening agent within 30-60 minutes. Carbamide peroxide releases about 50% of its whitening agent in the first two hours and it remains active for up to six additional hours. This means, products using hydrogen peroxide has shorter wear time but both active ingredients have similar whitening properties. The amount of product used and the time it will take to fully activate applies to each patient’s unique needs.
