What is a crown?
Crowns are an ideal way to rebuild teeth which have been broken, or have been weakened by decay or a very large filling. A crown is a restoration over that the remaining part of the tooth, making it strong and giving it the shape and contour of a natural tooth.
Why would I need a crown?

If a tooth is misshaped or discoloured, you can discuss with you dentist if a crown is suitable for cosmetic improvement.

What is a post crown?
In root-filled teeth it may be necessary to insert a post into the tooth root before placing a crown. A post gives support and helps the crown to stay in place and is indicated if the tooth is broken down to the gum level and root treated.
How long does the treatment take?
You will need to have at least two visits: the first for the preparation, impression, shade taking and fitting the temporary crown, and the second to fit the permanent crown.
How long will a crown last?
The life of a crown will depend on how well it is looked after. The crown itself cannot decay, but decay can start where the edge of the crown joins the tooth.

Will the crown feel different?
