Which tooth is it?
Did you get something hard?
Has there ever been a bite to the hard stuff this tooth has been broken?
Are there holes in your teeth that you can see?
Have you ever had any pain? Is there any obvious cause for pain?
Can you take a toothpick and put it on the surface of the tooth that hurts?
If all of the above answers are correct, then don't worry too much. Generally there won't be a big problem.
If it hurts every time, it must be something abnormal. I suggest you go to the hospital to check it, because I can't really know your situation accurately by your account.
Suggest to go to professional formal oral hospital to see a dentist!
