Carbamide Peroxide and Hydrogen Peroxide in Whitening Products

I get this question quite often in interpreting the actual strength of whitening products. In general, carbamide peroxide converts to approx. 3 times less hydrogen peroxide. (i.e. 22% carbamide peroxide is generally equivalent to 7.5% hydrogen peroxide). Ask your dentist about the comparative strengths and weaknesses of dentist delivered vs. off-the-shelf whitening products.

Take care
