Why Is My Dental Crown Sensitive?

Why Is My Dental Crown Sensitive?

No time is a good time for tooth sensitivity and many of you have experienced discomfort in a crowned tooth when you least expect to have problems. There are several reasons why a crown might become sensitive. Learn more about what could be causing you this bothersome pain:


Contrary to popular belief, dental crowns are not immune to decay entirely. Although the porcelain or metal material can’t get a cavity, the tooth edges and root surfaces still can. If not kept clean, a new cavity can form just like any other area in your mouth. Remember this formula:

Plaque + sugar = acid    acid + tooth = cavity

Reducing your sugar intake along with great home care habits will greatly improve your chances of keeping your crown margins decay free.

Periodontal Disease

When infection begins to destroy the bone holding a tooth in place, you most likely won’t feel the process happening. In the beginning stages, this disease is mostly symptom free but advanced stages can lead to quite a bit of discomfort.

Hang Loose

Crowns are essentially glued to teeth with strong cement. The bond between your tooth and the crown won’t last forever, especially if you clench, chew on ice, or put unusual forces on it.  When the cement loosens, sensitivity to temperatures and biting may start to bother you.

Bite Problems

Your mouth and jaw are riddled with nerves and the slightest change in your bite could have negative side effects on your teeth. If your bite isn’t exactly where it should be or if you are hitting too high on the edges of your new crown, the ligaments and nerves can become bruised. Usually adjusting the bite takes care of this short-term sensitivity.

The Nerve of it!

In some cases, the trauma from having a crown done is just too much for your tooth’s nerve to handle. The process of taking out decay and/or trying to repair a broken tooth to place a crown could cause the delicate nerve of your tooth to flare up. If this happens, we always have the option of performing a root canal to remove the infected or damaged area.
