“My teeth hurt when I eat hot food. What can be the cause?”

The likely cause is either a large cavity close to the pulp (nerve) or a nerve that may be process of dying in which case a root canal would be needed. I recommend getting it checked ASAP.

In almost all instances, heat sensitivity is a sign that the nerve/pulp inside your tooth or teeth is dead or dying (non-vital) and requires root canal therapy/endodontics. I would find an experienced general dentist to pulp test your teeth to find which specific ones are causing the problem. Many times the source may seem to be many teeth or non-specific. This is because the pain is what we call referred pain and you as an individual may not be able to pin point the source.

Hopefully it is just something temporary. Sometimes that can last for several weeks for whatever reason. Besides that, if it continues, the only way to really determine making a visit to your dentist.
