Hi Christine, no I have never tried a cigarette in my life, and drank only socially in the past and haven't had a drop in many years. Are you sure I should stop using Listerine? My dentist has always recommended I use it, and I've used it every day for about 10 years.

The small red patch sometimes bleeds a little when pressed. There is no pus or adjacent white areas, or any other symptoms to my knowledge. I'm just worried because it hasn't started healing at all. My dentist said if it hadn't been there for over a month he would have said it was probably just trauma. He recommends I have a biopsy. I'm very nervous and have been scouring the internet for what it could be.
