I have a tooth ache but do not know why
So a few days ago I was eating nothing to hard but I hard a crack noise in my mouth. I did not think much about it at the time because my teeth did not hurt and I did not see any broken teeth. Now whenever I chew I get a sharp pain in one of my back teeth. I have looked in the mirror but do not see any chips or cracks in my tooth. What can be causing my pain? Please help
