I've had problems with teeth on the right side of my mouth for a while now, one of my mollars(sp?) on the bottom was heavily filled and I started getting REALLY bad pain when eating, shooting so it felt like the top 2 teeth, the pain would come on after I'd finished eating and last for 10 mins or so.

So the dentist had a look, couldn't see anything wrong with the top ones, I have since assumed it's this heavily filled one.

The tooth is now sore when I push it, but not heat/cold sensitive, which leads me to think it's dead??

Went back today and he took the filling out and put a dressing on it, he mentioned it might be dead but I'm not 100% sure.

Options are root canal treatment, possible problems in future
Or take it out, big gap in my teeth, problems chewing?
