Why is my tooth sensitive to heat?

Answer by  temporarilyunemployed (42)

Having the same experience as you for most of my life, here's what I think is happening: those metal fillings in your teeth are a good conductor of hot and cold while normal natural teeth are good insulators. So that hot and cold from the food and drink blasts quickly to your nerve endings growing near your fillings.

This problem prevails every where, this is mainly caused by the softening of the tissues inside the tooth, bacterial infection caused by the storage consumed food. If the problem prevails your teeth won't respond to heat or cold. while you take some hot food it would hinder the taste buds.

Your tooth could be sensitive to heat for many reasons. One, you could have a cavity that is close to the nerve and it is starting to act up on you. Also if you recently had a filling that was close to the nerve the change could be making your tooth act up for a few days.

Sensitivity temperature - usually cold but also heat - is a classic symptom of the tooth being so inflamed that it is almost dead. Sensitivity to cold is less alarming than sensitivity to heat.
