Sinus infection and finished rtc pain? :(?

Question

I have a sinus infection and am taking meds,the problem is,the very back tooth that had a root canal and crown is suddenly very sore after 3 months,what happened? ty

Answer 1

If it's you upper back tooth, it's probably just the sinus infection causing the pain.  People often think they have tooth pain when it's actually sinus pain.  If you still have pain when your sinus infection is gone, it may mean a root was missed when your root canal was done or possibly the tooth is cracked from all the trauma or simply that your bite is a little high and needs to be adjusted.  It's probably just your sinus infection, though, so keep taking your antibiotics and some tylenol and try not to worry!
