Crown
If a tooth is damaged but not lost, a crown can be used to restore its shape, appearance and function. You may need a crown if you have a root canal, a large filling in a tooth or a broken tooth.
A crown, also called a cap, is a hollow, artificial tooth used to cover a damaged or decayed tooth. The crown restores the tooth and protects it from further damage. Crowns can also be used to cover a discoloured or misshapen tooth. A tooth that has been fixed with a crown looks and works very much like a natural tooth. |
There is a significant shift towards ceramic crowns. Sometimes gold or porcelain-fused-to-metal (PFM) crowns are used.
On average a ceramic crown costs $1300.
There is an expectation for crowns to last 10+ years, but the length of serviceability will depend on oral hygiene, personal caries risk as well as on dentist's skills.
In general, 2 appointments are needed for a back tooth's crown. Front teeth may require extra appointment as custom color-matching sometimes is necessary to make the crown blend in perfectly. Here are some steps to crown-making.

Why do some crowns last decades and some fail a lot sooner?
In general, the longevity of any product will depend on how well it is made and how it is used and maintained (cared for).
For a crown or bridge to last a long time at a minimum the following pay role:
For a crown or bridge to last a long time at a minimum the following pay role:
- Dentist's side
- tooth needs to be prepared well by a dentist (cleaned from decay, reduced sufficiently, but not excessively).
- dentist need to take a good impression of the tooth so that a lab technician is able to see how to shape the crown.
- crown is well made by a dental lab.
- quality control by the dentist before a final cementation.
- Patient's side
- good oral hygiene (brush, floss, Waterpik).
- catch and treat any other problems in the mouth (regular check ups, not letting adjacent teeth deteriorate).
- be mindful about mechanical limitations - don't use your teeth as tools!

This is an incidental finding while working on another tooth.
The crown on the last tooth has a gap (does not fit the tooth well). The decay will likely develop in that space as it is impossible for the patient to clean that space at home.
This crown will not last long and needs to be redone before tooth starts hurting.
