A crown or an onlay is a type of dental restoration used to fix teeth that have been broken, weakened by decay or contain a very large filling.
These days, crowns and onlays can be made of very strong porcelain material which is hard to differentiate from natural teeth. There is no metal in the restoration which gives it translucency just like your own teeth. The shade is carefully chosen to match the rest of your smile. No one will know that it's there.
Here is how it works:
- The tooth is prepared and an impression is taken
- A crown is custom made in the dental laboratory to fit the tooth precisely and match the neighbouring teeth
- The crown or onlay is bonded securely on the tooth
A crown could be a good solution if you have some discoloured fillings and would like to improve their appearance to give you a more appealing smile. Additionally, if you have had root canal treatment, you will need a crown to protect the tooth, allowing you to eat and bite down on it as if it was a real tooth.
- Strengthens remaining tooth structure
- Natural-looking restoration
- Functions like a real tooth, so you can bite and chew as usual
