I noticed a small pimple-like bump on my gums about a month ago. After a bit of research, I've come to suspect that it is an abscess. What seems uncommon, from what I've read, is that I've experienced little to no pain- only an occasional dull ache. My question is: if I'm experiencing little pain, and if it has only manifested for a month, is it possible that this can be treated by antibiotics alone? Or will a root canal or extraction be almost certainly necessary?
