I imagine it would feel like hell
**another answer:
personally I have a dead tooth, and I'll have it fixed at some point, soon I hope. But, as for feeling, there is none, only that it is embarrassing, as it's one of my front teeth. No pain, at least not for me personally.

If you completely break your tooth, like through the inside and everything, you will feel a lot of pain in your mouth. However, if by break, you mean you chipped the tooth, nothing really happens, but you can feel the break with your tongue. Either way, if you have dental insurance, you might get a filling for a chipped tooth, or a whole new replacement tooth if you broke the entire tooth.
p.s you is actually supposed to be I or I am.
