question: I have a persistent toothache. I brush and floss daily, but it keeps recurring. I watch what I eat as well, to avoid aggravating it. There is gum discoloration around the tooth as well. The pain hasn't been real excruciating yet, so I'm hoping there's a way I can fix this problem without losing the tooth, since I have already have lost a few. I use mouthwash a lot to help kill the germs. It temporarily helps the pain, but eventually it returns. Is there an inexpensive way I can ease the pain and eventually heal the tooth?
