Tooth ache in rootcanal tooth?
In the last 2 days I have this dull pain in my tooth (really high up, in the gums). It only hurts when I walk or bend down. It is not painful when I drink or eat. I had a root canal on this tooth in 2005 and it has a permanent crown on it. I did have a cold a few weeks ago and was wondering if it was turning into a sinus infection. No other teeth hurt though. Also, the tooth next to it also had a root canal and a crown on it. Any dentists out there? Think it is a tooth problem or sinus? FWIW, I am not having any nasal drainage and I do have a dull tightness in my head, near my frontal sinuses.
