What can i do about tooth heat sensitivity?

Sensitive tooth: I advise to check with your dentist.

See a dentist: Severe hot sensitivity is more ominous than cold sensitivity and could mean that your tooth has irreversable puplitis and may requires a root canal. If your teeth are mildly hot and cold sensitive, there is a possibility that it is a reversable condition. If you recently had some dental work done and are haveing sensitivity, contact your dentist to eval.

Nerve involvement: When teeth become sensitive to heat it usually means that the nerve of the tooth is involved. A root canal will treat the nerve and eliminate the pain.

Use Sensodyne first: The source of your sensitivity needs to be determined by a dentist first. It may simply be an exposed root that could easily be treated with a dentrifice like sensodyne. A root canal is only needed if there is irreversible damage to the nerve. Simply treating all sensitive teeth with root canals is like shooting flies with bazookas. Please see a dentist if a desensitizing paste does not work.
