What does it mean when a tooth hurts when you chew, from the pressure. I know-it means go to the dentist, but?

Question

that is not what I am asking. I want to know what causes it?

Answer 1

It could be as simple as a "high bite" where you are hitting that tooth a little too hard. Yes, this CAN happen all of the sudden as your teeth are constantly shifting and your bite changes. Usually, things just work out, but sometimes you need to get the tooth trimmed a little bit.

It is more likely that you have an abscess on the tooth, though, if it is bad enough to cause you to ask this question. As you bite on the tooth, the tooth wiggles just a little bit and pokes at the abscess causing pain. I have a hand gesture that I use to show this to my patients, but I can't figure out how to do it on Yahoo! It's like tapping on a balloon that is all blown up. When you tap, the balloon expands outward. The same thing happens with an abscess and as the abscess expands, it makes pressure on the bone and this causes the pain.

Answer 2

It means that something is irritating the nerve inside of the tooth. For example, if you have a cavity, once it gets deep enough, the nerve is exposed to the outside world. Then, when you eat something, it goes in the cavity hole and touches the nerve. Hence, the pain.

Answer 3

maybe your teeth is sensitive or you have cavity, the nerve in your tooth response when you have stimuli like heat,cold or pressure (chewing food) if you dont have cavity, the nerve or pulp normally dont response, but when you have cavity, the pulp will response(PAIN).

juz go to the dentist..hehe
