Is it normal that i feel a heartbeat in my teeth?

I´d say it sounds like an infection.

It's normal, u just have a stronger pulse in your teeth than others.

(s)aint is right; it could be a sinus infection if it feels like a heaviness or throbbing in your gums. If you walk heavily or jump up and down, do you kinda feel it in your gums?
Apparently dairy is the thing to steer clear of, if that's what it is. But it might not be.
Sometimes I can hear/feel blood pumping in different places just depending on how I'm lying down or whatever. I don't tend to worry unless it's painful.
