My teeth are sensitive to hot and cold sensations. What causes this problem?

Tooth sensitivity can be caused by a number of reasons. Some of the more common culprits are cavities, cracked teeth, broken fillings, grinding your teeth, and receding gums. Everyone has microscopic tubules in their enamel that connect with the nerve of a tooth. If these tubules are exposed, temperature changes from eating hot or cold foods are transmitted more easily too the nerve. If your sensitivity is from a cracked tooth or grinding, then the changes in pressure on the tooth are causing your sensitivity. If your sensitivity does not go away after a few days, you can call 1-800-4Braces for a free consultation to discuss this problem.
