Complications With a Dental Crown

A dental crown is a tool that your dentist can use to both strengthen your teeth and improve the appearance of your smile. Most dental crowns are designed to last for seven years but some can last for more than 40. While it is a permanent dental appliance, there are some complications to look for.

  1. The Facts

    • A crown covers the top of a damaged tooth to protect it and conceal it. You might need one if you require a filling so large that there will not be much original tooth left, if you have a root canal or if you have a broken tooth. Potential complications include increased risk of gum disease.

    Lost Crown

    • One potential complication with a dental crown is the risk that it might come loose and detach from the tooth it covers. If this happens, you might accidentally swallow it. If you have the crown, you will need to save it and see your dentist right away. While you can purchase temporary dental cement in most drug stores and use that to put your crown back in place for the time being, a dentist is the only one who can permanently restore it.

    Gum Disease

    • The remaining part of the tooth that a crown covers is still at risk for tooth decay. Crowns can attract plaque that can be difficult to remove. If plaque builds at the gum line, you can develop gingivitis and even periodontal disease. Careful brushing and flossing at home as well as regular dental cleanings can help you reduce your risk.

    Fracture

    • Dental crowns are constructed out of a variety of materials, including porcelain, metal alloys and porcelain fused with metal. Porcelain crowns are at a higher risk for complications like fracture or breaking if placed under enough pressure. If your crown fractures, part of it might break off. The tooth it covers could be exposed, leading to discomfort. You will need to see your dentist to have the damaged crown repaired or replaced.

    Other

    • Another potential complication of a dental crown constructed of porcelain and porcelain fused with metal is wear and damage to your other teeth. This occurs when the porcelain of your dental crown becomes rough or worn. The rougher material rubs against the teeth that come in contact with the crown, wearing away the enamel. If the wear progresses far enough, you might require a crown on the other teeth to repair the damage.
