What is a crown?
A crown is a prosthetic (artificial) tooth which sits on top of an original tooth that has been weakened in some way- usually by a large filling, root canal treatment or decay. Your Dentist will recommend a crown when the strength of your tooth has been compromised and it is no longer possible or satisfactory to place a filling.
Your natural tooth consists of a crown and a root. The crown is the part we can see which sits above the gum, while the root is the part we cannot see below the gum. The root secures the tooth to the jaw bone.
Your dental crown will be a bespoke replacement for the natural crown mimicking its size and shape plus it will match the colour of your other teeth so that it blends perfectly and feels as natural as the rest.
Made from either porcelain, zirconia or gold, crowns are very strong and can be expected to last for many years provided that they are well maintained and regularly checked.
How long is the process?
The fitting of a crown will take about 2 weeks:
Your old tooth will be cleaned and any decay removed. It will then be reduced to ensure there is enough room for the new crown to be fitted on top whilst keeping it in line with your other teeth. This will take place under a local anaesthetic. Next, impressions of your teeth will be taken and used to produce a crown. A temporary restoration (temporary crown) can be fitted in the interim if required.
When finished the final crown will be positioned for optimum comfort and then cemented in place.
A crown is recommended when a natural crown has been weakened by a large filling, root canal treatment or decay.
Typically 2 weeks from tooth preparation to crown fit.
With good oral hygiene and a low sugar diet, crowns may last a lifetime.Read More
