What is meant by a dental crown?
A crown is simply a tooth-shaped cap fitted over a tooth to strengthen and protect the tooth structure. Most crowns will be made of a hard, white substance to make them look natural.
A crown will fit over the remaining part of a tooth that has been prepared which makes it stronger. It is also sometimes known as a 'cap'.
Why would it be necessary to have a dental crown?
Crowns are ideal to repair broken teeth or teeth that have been weakened by decay or by a very large filling. Other instances when a dental crown would be used would be:
- To improve the appearance of discoloured fillings
- After a root filling a crown will protect what is left of the tooth
- To help hold a bridge or denture in place.
What material is used to make a dental crown?
Crowns could be made of a variety of different materials with new materials continually being introduced. Some popular options are:
Porcelain bonded to precious metal: most crowns are made from this. A precious metal base with porcelain layers applied over it.
Porcelain: made entirely out of porcelain and consequently not as strong as the bonded crowns are. They can look very natural and are most often used as crowns for front teeth.
Ceramic: this modern technique can offer an alternative to metal, and can give all the strength of a bonded crown with the look of a porcelain crown - suitable for all areas of the mouth.
Glass: these crowns have a very natural appearance and can also be used anywhere in the mouth.
Gold-alloy crowns: gold has traditionally been one of the oldest filling materials. Used with other metal alloys it increases strength, and that makes it very hardwearing. These crowns will be coloured silver or gold.
How is a dental crown manufactured?
First your dentist will shape the tooth ready for the crown. This will mean removing a layer of the outer surface. The amount of tooth removed will be equal to the thickness of the proposed crown.
After the tooth is shaped, the dental team will make a mould of the prepared tooth and one of the opposite jaw and then possibly another one to show the way your teeth bite together.
The impressions will then be given to a dental technician, along with information about the shade to use and any other information they might need.
What is meant by a post dental crown?
If a tooth is root-filled a post may be inserted into the tooth root before a crown is fitted to support the crown helping it to stay in place. The surface of the tooth may also be removed down to the level of the gum.
A post might be made of prefabricated stainless steel that would be fitted directly into the root canal or a custom-made post constructed to fit the shape of the prepared root canal, the post in the root canal is cemented in position, ready for the crown to be fitted.
Are there any alternatives to post crowns for root-filled teeth?
