Just one. He said there was an abscess but didn't give me any antibiotics, he just took the tooth out. Will it clear up by itself? I know there will be swelling from the tooth being taken out but the lump/swelling still feels exactly the same as before. Is it possible that the infection was under another tooth aswell or something?

Just to clear things up, when I said the hole started at the tooth behind it I didn't mean that tooth was decayed aswell, I meant the infected tooth was sort of cut off half way and there was a hole from the middle to the tooth behind it. I don't know if I'm explaining it correctly but I've only had pain coming from one tooth and only one decayed tooth.

Actually, since he took it out I've had pain coming from the tooth INFRONT of the one he removed. Could that just be bruising?

Sorry if I'm asking completely stupid questions, I really know nothing about teeth.
