Hi, I was wondering if anyone could help me. I had my top wisdom teeth taken out a few years ago and they heeled perfectly with no problems. But lately I've been get discomfort in the back right gum and feeling with my gum, I think I can feel a hole there that has developed. I've tried googling, which is never good I know, but it said it could possibly be trench mouth..I was just wondering if anyone knows or has or had the same problem. And whether I should call the dentist to make an appointment. Any responses would be greatly appreciated x
