A crown is a restoration that is placed over a tooth and held in place by a dental cement.
Crowns are used for several reasons including
- as a protective cover for badly decayed teeth and fractured teeth
- as a permanent restoration for teeth with large fillings and root canal fillings
- to correct minor problems in natural teeth like spacing and irregular shape or severe discolouration.
Crowns can be made of metal or porcelain or a combination of the two.
How long do crowns last and how do I care for them?
Crowns are made of inert materials that do not deteriorate over time. However, the underlying tooth is still prone to decay and gum disease. Daily brushing and flossing are essential for maintaining good oral health as well as keeping the crown trouble-free. The most vulnerable portion of the crown is the margin or the junction between tooth and crown.
A Bridge is where a missing tooth is replaced by a porcelain tooth. the porcelain tooth can be attached to the adjoining teeth by crowning them, or in certain cases with a resin cement.
A Veneer is a thin layer of porcelain that is adhered to the front surface of the tooth with the aim of improving the appearance of the tooth.
