We're glad you love your whiter smile, but are sorry that you also experienced sensitivity with daily use. Flavor oils, surfactants/foaming agents, tartar control agents, and abrasives all have some potential to cause irritation. To minimize these effects, don't brush too hard or more than 2X daily and use a soft bristled toothbrush. While all of our products are safe and effective, some people may not tolerate a particular formulation. If irritation persists or becomes uncomfortable, you should discontinue use and consult with your dentist. Your satisfaction is very important to us, and we’d like to talk more with you if you'd like further help. Please give our Crest Team a call at 1-800-492-7378 from 9AM -- 6PM EST Monday–Friday.
