Looking for help for a tooth abscess. Have you ever had a tooth abscess? If so how did you clear it up? Did you leave it alone to clear up by it self? Or did you need to got to the dentist? How did the dentist treat you abscess? I am in a lot of pain and not sure what to do. I was told a dentist could not fix your tooth if you have a abscess. Is that true? Advise please.
