A somewhat large piece broke off the front inner corner of my lower left molar. there's no pain (now at least), but i'm worried. what should i do?

Seea dentist !: Not much more you can do on your own. Fractures can be caused by many different things.

Dentist: Teeth break, especially if previously fractured or if there is a large cavity. This is not a do-it-yourself project. Please see a Dentist as soon as possible to treat your small problem before it becomes a big problem.

See dentist: Make an appointment to see your dentist. If tooth broke because of decay, the sooner it is fixed the easier and less expensive. If tooth broke because it was weak and has no decay, it is a less urgent situation.

The simple solution: See a dentist for evaluation, x-rays, diagnosis and treatment options.
