What medicine does eating hot and eating cold toothache use?

There are countless tubules on the root surface of teeth that lead directly to the pulp nerve. Temperature or mechanical friction can stimulate nerves and cause soreness. There are four common causes of dentin hypersensitivity:

Gingival atrophy;

Wear of enamel;

Tooth decay;

Cracked teeth.

How long have you had this symptom? Does a big tooth hurt or only a part of it hurts? If it takes a long time, or if you feel strongly stimulated, it is recommended to go to a nearby stomatological hospital for examination and diagnosis, and at the same time change the anti-allergic toothpaste to relieve the irritation symptoms.
