NiteWhite 16% Carbamide Peroxide

Exactly what I used to get from the dentist at three times the price!

I've been using carbamide peroxide for years with my retainer - using it 1 or 2 x year overnight. My teeth are very white and I have had no dental issues.

There is no tray to put the gel into. The directions say to put in the tray and then into your mouth.
