My tooth has started to hurt only when I run! (or tread heavily) Any ideas why?

Question

Thanks!

Answer 1

You could possibly have a sinus infection... Your sinuses are located RIGHT above your upper teeth, so any pressure in there will refer to your teeth, especially when you are running or bouncing and forcing pressure on your maxilla. If this is the case, you can see a dentist about getting an x-ray to see if there is pressure in there. A simple antibiotic would take it away. I can't think of anything else though that could possibly affect your teeth while running...

Answer 2

A couple of mine do that too, and they have had work done on them.  The cavities were very close to the nerve, so when the blood pumps, or even if you bite to hard, they're sensitive and can feel everything.

I think it's possible if you've had no work done on them if your teeth are very sensitive like mine.
