Do you have crown pain? A dental crown covers and protects a damaged tooth, but many people are surprised to learn that it will not protect them from tooth pain. Moreover, a crowned tooth is more prone to issues than an uncrowned tooth.

There are numerous reasons why your dental crown is causing pain. You may experience discomfort, sensitivity, or pressure where the crown is located. You could also have a constant toothache.

What is a dental crown?

A dental crown is a cap-like dental appliance that covers a damaged tooth. The crown's function is to restore the size and shape of a tooth while also protecting it. Dental crowns are sometimes placed on either side of a missing tooth to support a bridge.

Furthermore, crowns are available in various materials such as porcelain, ceramic, and metal. You may require a dental crown to protect the tooth after a root canal procedure. Your dentist will recommend you a crown if you have:

  • A large cavity is too large to fill with a cracked or weakened tooth.
  • A missing tooth that requires a bridge or implant
  • Discolored tooth

Reasons why you are having pain in a tooth that has a crown

Tooth decay under the crown: Because the tooth beneath the dental crown is still intact, tooth decay or a new cavity can form at the tooth-crown junction. This can result in chronic pain in the affected area. As a result, a root canal procedure may be required if a tooth cavity becomes large enough to affect the nerve.

Infection: An infection develops when the crown presses against a traumatized nerve. Infections can also occur due to old fillings beneath the crown leaking bacteria that infects the nerve.

Infection symptoms include:

  • When you bite your gum, you feel pain.
  • Swelled gum
  • Fever

Sore gums after the procedure: You may experience temporary discomfort following a crown placement. This discomfort should not last more than two weeks. Consult a dentist if you are in a lot of pain after a crown procedure or if you suffer from pain after two weeks.

A fractured tooth or crown: Mild pain can be caused by a cracked crown or a tooth underneath a crown. Because of the crack, you may be sensitive to cold, heat, or air. If you notice that your crown is broken, loose, or cracked, you should consult your dentist for repair.

Gum recession: When you brush your teeth too hard, it can cause gum recession. Therefore, when the gums recede, they become more prone to plaque buildup and gum disease. If the gums around your crowned tooth have receded, exposing part of the tooth's root, you may experience pain and sensitivity.

The crown does not fit properly: If your crown does not fit properly, you may experience discomfort. When you bite down, the pain usually indicates that the crown is too high on the tooth. An improper fit may also have an impact on your bite or smile.

Like your other teeth, a dental crown should fit into your bite. If your bite feels "off," it may cause jaw pain and headaches.

How to prevent dental crown pain?

You can avoid dental crown pain by practicing good oral hygiene. Make certain to:

  • Brush your teeth twice a day
  • Floss daily and visit the dentist regularly
  • Avoid chewing hard foods like nuts and ice, which can cause crown damage.

You should see a dentist if your tooth pain is severe or does not go away. You may require a root canal, crown replacement, or tooth extraction.


You may feel discomfort after having a crown, but it should go away after a few weeks. However, if your toothache persists, consult a dentist to determine the source of the problem. Infections, cavities, fractured teeth, and other issues could be the source of your discomfort.
