Drinking or eating cold things |

Touching the teeth with other teeth or the tongue |
| |
| Some Causes of Sensitivity: |

 |
Poor oral hygiene — This may allow tartar to build up at the gum line, leaching minerals from the tooth. |
 |
Long-term tooth wear |
 |
Untreated cavities |
 |
An old filling with a crack or leak |
 |
Receding gums that expose the tooth’s roots — Receding gums often are caused by periodontal diseases or by brushing too hard. |

 |
Excessive tooth whitening in people who have tooth roots that already are exposed |
 |
Frequently eating acidic foods or drinking acidic beverages |
