In this video, Dr. James Slaman discusses the purpose of dental crowns, candidacy requirements, and how long a crown lasts. You may need a dental crown if you have a broken or decayed tooth, or a tooth with a large filling that needs replacing. The crown can last more than a decade with proper care.View transcript
A dental crown is a prosthetic dental device used to restore a tooth that's been damaged by trauma or extensive decay or a tooth that's been treated with a root canal. Dental crowns can be made out of ceramic materials that look like natural teeth. They can also be made out of metallic materials, such as cast gold, which offer a higher level of strength than ceramic restorations. Good candidates for dental crowns are patients who have extensively decayed, broken, or teeth that have been treated with the root canal therapy. Sometimes, teeth that have had large fillings, an alternative to a dental crown might be a partial crown called an overlay, where a portion of the tooth is covered with restorative ceramic or gold, and the healthy remaining tooth structure is preserved. On average, a dental crown will last a decade or more. The crown requires the same care and maintenance as your regular teeth would, daily flossing, twice daily brushing.
