Crowns restore, preserve functionality and improve the appearance of your teeth. They are commonly known as caps because they sit on top of a prepared tooth.
There are two main types of crowns available: NHS metal bonded crowns and private porcelain crowns. Metal bonded crowns don’t look as natural as the porcelain ones because they tend to look dark and hence don’t really look like normal teeth. The porcelain ones, also known as ceramic crowns are the state-of-the-art solutions for patients looking for the best restoration. They reflect and refract just like natural teeth. They are also less sensitive to heat and cold unlike the metal bonded ones.
Why might I need a crown?
- If your tooth is decaying and there is not enough structure left to support a filling
- If your tooth has been fractured beyond repair composite bonding will not work
- If you have a large cavity and need additional protection
- As part of a dental implant treatment
- As part of a root canal treatment
- If your teeth have eroded, you may need a Crown
- To improve your smile
Are dental crowns the best option?
Crowns should not be the first choice because a large part of teeth has to be removed in order to perform the treatment. Veneers or dental bonding restorations might be a less invasive option.
However, crowns are required when extra strength is needed. Veneers and dental bonding restorations are only as strong as the tooth.
Full ceramic crowns are just as hard wearing as metal bonded crowns and are the most aesthetically pleasing option. They are made entirely from a ceramic material, usually porcelain, which looks and feels like a natural tooth. With traditional metal bonded crowns, only a thin layer of porcelain is used to cover the metal crown so patients can sometimes be left with a metal line near the gum.
