I have an abscess tooth with draining out of my inside gum into my mouth. After having the abscess, with very little pain so I did not know it was an abscess, I started to get a stomach ache especially at night. I am going to the dentist Tuesday for a root cannel fix and re application. Does anyone know if a tooth abscess can cause stomach pain or ache. I don't want to be jumping to conclusions about this pain so any advice would be great thanks

Did the dentist put you on an antibiotic? It could be the medication that is causing your stomach problem.

I would think that swallowing any pus that is draining from your abscess could cause some stomach upset as well.

Don't know about stomach aches, but left untreated, tooth absesses can lead to death. You need to get in to see your dentist ASAP.

Maybe it's nerves about your upcoming procedures...
