Mt dentist also made trays for me to use. 2x a day for five minutes each. The radiation doctor I had said that sometimes the floride will turn your teeth brown so if you use them for long periods, check the color of your teeth frequently. I was told that the floride was to make your enamel harder thus less prone to decay. Pulling a tooth AFTER palate area radiation is very complicated due to the jaw bone being damaged and not able to heal easily.
