Yep, I am. I had my semi-annual trip to the periodontist today where I had another Sodium Fluoride treatment. The hygienist cleans your teeth (not as thoroughly as my regular dentist’s hygienist does, but still pretty well), dries them off, and starts painting this stuff on. It dries quickly, and when it does it looks a little like your teeth are made of baklava.
My dentist’s hygienist usually does that one to me. It tastes a lot better now than it did when they first started using it!
