When I was much younger than I am today, a normal dental cleaning, and I had to have a filling fixed The second I got the Novacaine to fix the tooth is when My oral planus Started. Last year I had a dermatologist tell me to use children’s toothpaste and he told me to use Tom’s strawberry, fluoride, free toothpaste. My mouth is much better and I have not had a flareup after going to the dentist since then.
