Teeth expand and contract in reaction to changes in temperature. Hot and cold food and beverages can cause pain for those with sensitive teeth.

Over time, tooth enamel wears down, gums may recede or teeth may develop microscopic cracks, exposing the interior of the tooth and irritating nerve endings. Just breathing cold air can be painful for those with extremely sensitive teeth.

If you suffer from sensitive teeth, talk to your dentist about the appropriate treatment options. Treatment ranges from using a special tooth paste to desensitize the tooth, to more complex treatments like crown placement, inlay, bonding or gum graft.
