A crown can be required for a variety of reasons. Most commonly, a tooth that has a large filling or has sustained a fracture will need a crown. In these instances, a crown is required to maintain the structural and functional integrity of the tooth. Teeth that have undergone root canal therapy require a crown for the same reasons. Teeth are also crowned to improve aesthetics.
Types of crown
There are three basic types of crown. The first type of crown is made entirely of gold. For cosmetic reasons, this is usually placed on back teeth. A second type has a layer of tooth-coloured porcelain covering the metal, improving the look of the tooth while maintaining strength. These can be done on front or back teeth. A third kind of crown will be made entirely of porcelain. Cosmetically, these are the most appealing but they’re usually reserved for use on front teeth. Each type has different advantages and disadvantages. Your dentist can help you decide which will best suit your needs.
What is the procedure?
Generally, it takes two appointments to prepare and cement a crown. During the first visit, the tooth is shaped to allow room for the thickness of the crown and a temporary crown is provided while the new one is being custom made. The second appointment is the fit appointment where the temporary crown is removed and the new one custom fitted. Sometimes patients visit to the lab prior to the second visit, so that the technician can match the new crown exactly with existing teeth to ensure it looks as natural as possible.
A crown is the most reliable and predictable way of restoring strength to a weak tooth. The new crown will look, feel and function just like any of your natural teeth. Porcelain crowns may also be the best way to improve the look of your teeth. Ask your dentist if crowns could help restore and protect your teeth, as well as improve your smile.
