What causes teeth to become sensitive to hot and cold?

Receding gum tissue could be the cause of sensitivity. As gum tissue pulls back away from teeth, the root of the tooth becomes exposed. A soft tissue graft would be the recommended treatment. Other treatment suggestions might include using a fluoride mouth rinse or switching to a toothpaste made specifically for sensitive teeth.
Visit your dentist so that you can be diagnosed and treated properly.
