Question:
What is the best tooth whitener?
I've tried the Rembrandt tooth whitener (about 5 tubes that you use over a certain amount of weeks). It made my teeth a few slight shades whiter but I realized that after consistently using it, one day, it starting to make my teeth slightly yellow! It's like the process reversed itself! I know - it doesn't make sense but I tried their system twice and this happened both times. I've tried Crest White Strips but it makes my gums TOO sensitive. The stuff is terrible. It works but the chemical are too harsh on the gums. What do you suggest? What has worked? I can't take anything that will make my teeth or gums sensitive. Toothpaste? Strips? Trays?
