Why are teeth sensitive to hot and cold? Will the sensitivity go away on its own?
Aug 1st, 2008 by Dr. Kourosh Maddahi DDS
There are several reasons that teeth might be sensitive to hot or cold including:
• Clenching or grinding the teeth
• The enamel of the tooth being gone
• Gum recession where the roots are exposed
• If there are cavities
Sometimes, when sensitivity is due to gum recession where the roots are exposed, brushing with fluoride toothpaste helps to plug up the holes at the roots and the sensitivity goes away. If the sensitivity is due to another reason it may not go away and it is best to have your teeth examined by a dentist.
