What is a dental crown?
Your dentist has suggested that you restore one of your teeth with a dental crown, but what exactly is a crown?
A crown is often the restoration of choice for teeth that have been weakened by a large filling, a major cavity, several cracks or a root canal treatment. …. By covering and completely surrounding the tooth, the dental crown has a crimping effect that prevents the appearance of new cracks and reinforces the strength of the tooth.
Dental crowns can be made of several different materials, each with its own advantages and disadvantages (all-ceramic, gold, porcelain-covered metal framework, zircon, e-max, etc.). They can be made by machining at your dentist’s office from a digital impression of your tooth (e.g. Cerec, E4D, 3Shape) or made in a laboratory from a model of your teeth obtained from a conventional impression taken in your mouth. Your dentist will be able to advise you on the type of dental crown to choose for your specific condition.
When a root canal has been performed on a tooth that requires a crown, a pivot, which consists of a pin inserted into the root of the tooth, may be necessary.
