Atypical odontalgia is the medical term used to describe an ache or pain in which area of the human body?

Thank you for a common sense question!

After chewing on some very hard antacids, I began having a bad toothache and thought it was a cracked tooth. The dentist could not find anything wrong with my tooth. He sent me to a specialist who also said my tooth looked healthy. This pain lasted for over 2 years and then suddenly went away on its own.

You had me at "dont"

I had pain for over a year in a tooth that had a root canal. The dentist said that was impossible but I guess not. Finally went away.
