Hi, for the last few weeks, I've been using an alcohol free fluoride mouth rinse. I don't have cavities, root or gum problems. My teeth and gums weren't sensitive, and I haven't changed any medications. I missed a couple of days and my teeth and mouth felt better. I'm doing what the directions say-combined with directions from my doctor. I was eating icy sherbet and drinking hot drinks and soups. My dentist won't be back until 2 weeks from now. I tried to call Crest- mouth wash, but I was on hold for about an hour, then was disconnected. I use a very soft tooth brush. Does anybody have any ideas?
