Dental crowns are versatile restorations, which may be recommended if you have a damaged or decayed tooth. Crowns are sometimes known as caps, as they sit on top of the existing tooth structure.
About dental crowns
Dental crowns are used to restore the teeth. They are placed over the top of your natural tooth, and they help to add stability and strength. You may be advised to have a crown if your tooth is infected or you’ve sustained dental injuries. Crowns can be made from metals and ceramics. Porcelain crowns tend to be very popular because they produce the most aesthetically-pleasing results.
Before a tooth is crowned, it must be prepared. Your dentist will remove any decayed or damaged tissue, and then shape the tooth ready for crowning. An impression of the tooth is created, and this is sent away and used as a template by a highly skilled dental technician. When the crown is ready, it is then returned, and your dentist will fit and secure it.
In most cases, crowns are used to treat decayed teeth, sometimes following root canal treatment. However, they can also be used to replace missing teeth; in this case, they are attached to dental implants.
Crowning the tooth is beneficial not just because it makes the tooth more robust and effective; the procedure also helps to reduce the risk of further infection.
How long should a crown last?
It’s not possible for crowns to decay; however, the tooth tissue that joins the crowns can become decayed, so it’s essential to maintain good standards of oral hygiene. If you look after your crown well, it should last around 5-15 years depending on the material used. When you see your dentist, they will check your crowns at every appointment. If you have any problems with your crown, make sure you seek advice, rather than waiting for your next routine check.
