A crown is a replacement outer covering, much like a thimble, that fits over and strengthens a tooth and restores its appearance and function. A crown is needed if a tooth has been extensively damaged by:
- Tooth decay
- Fractured or broken section of a tooth
- An old, large filling that is coming apart or failing
Types of Crowns
There are different types of crowns for different purposes. The most common type of crown is a porcelain crown with a ceramic, or sometimes metallic, core to give it strength. These crowns are very strong and look like a natural tooth. The metal inside the crown is often an alloy of gold. On the back teeth, or molars, especially where it is difficult to see, a gold crown is often the perfect choice because of its strength and durability (average durability is 20-40 years with good hygiene and dental care).
The procedure for affixing a crown:
- Shaping the tooth to remove the decay in or around it.
- Re-sculpturing the tooth to provide an ideal fit for the crown.
- Making a digital image of your teeth in order to create a custom-made crown.
- Making a temporary crown out of tooth colored resin and fitting it onto the tooth during the interim period until the permanent custom-made crown is being created.
- Applying the permanent crown when it is received from the lab by removing the temporary crown and fitting the permanent one onto the tooth.
- After ensuring that the crown has the proper look and fit, the dentist cements it into place.
Crowns can be expected to last for a number of years providing the person performs good oral hygiene and has regular professional care. If you are in need of a crown, please contact our Gladstone and Kansas City dentists today to schedule your initial appointment.
