Crowns are a type of restoration which can be used to strengthen a tooth that has become worn or damaged. Crowns are also known as caps because they fit over the top of the tooth. In addition to protecting the tooth and making it stronger, crowns can also have a marked effect on the aesthetics of the smile.
Why would I need a crown?
You may need a crown if you have a tooth which is decayed, damaged or worn. Crowns are usually used to protect and strengthen a tooth and are often needed after root canal treatment. Crowns can also be used for aesthetic reasons.
Crowns can be made from a variety of materials:
- Precious metals
- Metal alloys and ceramic materials
In some cases, crowns are made from porcelain bonded to metal. This helps to make the crown strong and natural looking, but complete porcelain crowns may be preferable as metal alloy can cause grey lines to develop around the gum line.
Benefits of crowns
Crowns strengthen the tooth and help to protect against decay and damage. They are also designed to blend in with the natural teeth, creating a more aesthetically pleasing smile.
How long do crowns last?
Crowns do not last forever but if you maintain a good oral hygiene routine they will last for many years.
