I used 35 % carbamide peroxide gel for half hour every day for two weeks. My teeth are nowhere as white as they should. I spoke with my dentist but no good advice was given. I don't drink coffee or smoke. My teeth are still yellow. What should I do ? Increase the duration and frequency of breaching?
