How long do dental crowns last?

Dental crowns can last about 10 - 15 years. How long a crown can last largely depends on the amount of wear and tear of the crown, and how well you care for the crown with good oral hygiene habits. Other factors like grinding or clenching teeth, or using your teeth to open things can also affect how long your dental crown lasts.

What problems may occur with a dental crown? 

Discomfort or Sensitivity

You may feel some sensitivity or discomfort when the anaesthesia for the new crown wears off. If the tooth with the crown has an intact nerve, you may feel some sensitivity to hot or cold foods. In this case, you may want to use toothpaste specifically meant for sensitive teeth.

There might also be pain when you bite down, and this normally signifies that the crown is too high on the tooth. In this case, you may wish to visit your dentist to fix the issue. 

Chipping and cracking

Crowns made from porcelain or porcelain fused to metal may chip. If it is just a small chip, the dentist can use composite resin to repair the chip. If the chipping is substantial, the crown may need to be replaced.

Loosening of the crown 

The cement may be washed off from under the crown, which causes the crown to loosen. Be careful as this may allow bacteria to seep in and cause decay to the tooth. Contact your dentist to fix your crown if it is loose.

Crown falling off 

Crowns may fall off for various reasons such as decay of the tooth or loosening of the crown. If the crown comes off completely, clean the crown and also the tooth that the crown was covering. You may wish to replace the crown temporarily using dental adhesive or temporary tooth cement. However, you should also visit your dentist to re-cement the crown in place properly or get a new crown. 

Allergic reactions 

Some metallic crowns are a mixture of metals that can cause allergic reactions in some people, but this is rare. 


When will a crown need to be replaced?
