Sensitve Teeth Preparation for Teeth Whitening?
I have somewhat sensitive teeth and want to know what I can do before I use my Opalescence to prepare for a good experience. I heard about things you put in trays, special toothpaste, ointment. Please let me know what works the best. Also, someone online said to put the whitener (not a lot) directly on the teeth (not in the tray), then, put the trays on and the whitener is less likely to get onto one's gums. Is this reccommended? Thanks!
