What can cause tooth pain

It’s hard to know for sure, but there are many possibilities.  If the tooth has no obvious dental issue, it might be a serious infection of the root canal, abscess, toothache, or periodontitis.

what other possible causes could there be?
user
Hm.  Well, tooth decay and grinding might cause pain, as might an abscess.  That’s it I think.  It might help you to be more specific about the pain you’re feeling.  What is it like?  Is it sharp or dull?  Is it constant or does it come and go?  Does it radiate anywhere?  Do you have sensitivity to cold or heat?  Is it getting worse or better over time?
