Dentistry/Sinus or tooth


I'm 67 and a runner. In excellent health but have had a lot of  dental problems over the years.
A couple of days ago I suddenly started having an ache around my gums above my upper rear teeth. The ache is only when I drink a hot liquid, not cold. I also have the pain after a run, not during. The pain only lasts a few minutes and then dissipates.  My dentist is out of town this weekend but by phone his staff looked at my last X-rays and showed no problems. All uppers are crowns and have had root canals. I've tapped on every tooth with ice and no problem. Could it still be a tooth problem or maybe sinus?  Also, I swam a mile in a pool 3 days ago.....could that be a causal factor? Thanks

Dear Don,

Sounds more like tooth than sinus.  Hot and cold sensitivity on a specific tooth or teeth usually indicates early infection in the tooth's nerve.  But you say you have had root canals in all your upper teeth.  So, there should be no nerves in your upper teeth to cause pain.

My guess is that you still have a nerve in one or more of your upper teeth.  Maybe you forgot, and the dentist made crowns over teeth that still had living nerves.

If all your upper teeth really did have root canals, and you're still feeling pain to hot, then there is still some small amount of nerve material left in one or more of your upper teeth.

My bet is still that there is an offending tooth nerve somewhere under your crowns.  Might even be a lower tooth nerve that's inflamed, and you're feeling it in an upper tooth.  I doubt it's your sinus (but anything is possible).  What you need now is an excellent dentist-detective.

Good luck, and let me know what you find out.
