I have a back tooth that has a cavity. I known about it for the past year or so since I can feel the hole with my tongue. I also get food stuck in it once in a while which really hurts. I was putting up with it because I have no job and no real money.
I just do odd jobs when I can. However now I think that I may have an infection going on by it because it has really been hurting lately and my mouth has a bad taste to it. What can I do besides going to the dentist. How can I clear up an infection?
