Frequently Asked Questions on Teeth Whitening


What is Carbamide Peroxide?

Carbamide peroxide (also known as urea peroxide) is the most popular over-the-counter and professional bleaching agent used for teeth whitening. The main and active ingredient in carbamide peroxide is hydrogen peroxide. Carbamide peroxide has the effect of oxidizing stains, which leaves teeth looking whiter.

Dentists usually use another product with carbamide peroxide or hydrogen peroxide when undergoing in-office teeth whitening, so when it's formulated into over-the-counter bleaching products, carbamide peroxide appears in a lower concentration.

Generally speaking, tooth sensitivity after whitening correlates to the carbamide peroxide concentration.
