is there a higher percentage of carbamide peroxide than 10%?
Question:
Answers:
Whitening products containing Carbamide Peroxide come in 16% and 22%; however, these are only available through your dentist. Newer formulations come with an additive ACP (Amorphous Calcium Phosphate and Potassium Nitrate) which are supposed to reduce sensitivity. There are also products that contain Hydrogen Peroxide instead of Carbamide Peroxide. Increasing to a higher percentage will actually increase the sensitivity that you are experiencing. My advice to you is not to use it overnight. Use it for and hour or two each day, if that doesn't improve the sensitivity, try alternating days (using it every other day). Higher percentage formulations should be used for even less time!
Yes, we were using 22% today , not sure if there is a higher one..
