Sorry for bad English.

I was chewing on my food and bit something hard, which caused my tooth to break and a part of it came off. It is a third tooth behind my upper left fang. I'm not sure how much of it got separated compared to the whole tooth but maybe an eight or so. A big part of it came off right to the gum/root or whatever it is. I can feel it soft inside with the tip of my tongue. It hurts when I eat some sweet food. The pain doesn't always disappear like when you feel a cold run down your tooth, it tends to stay. However, it goes away when I brush my teeth. Also, when I suck air into the left side of my mouth, it feels kind of breezy (not in a pleasurable way) where the soft part is. Please explain me more about what I'm in, what should I do? Please help. :) Thank you :)

#1... go to a dentist. They can determine if it can be fixed with a simple filling (which I doubt), or if a crown or cap can do it.. or its too bad to fix and must be pulled.

If you do nothing you will suffer and evenually lose the tooth for certain.
