Crowns in North London
A crown is a cap that is placed over a tooth and held in place by dental adhesive or cement.
Crowns are used for several reasons:
as a protective cover for badly decayed teeth or fractured teeth
as a permanent restoration for teeth with large fillings
to correct minor problems in natural teeth like spacing and irregular shape or severe discolouration.
Crowns are made of inert materials that do not deteriorate over time. However, the underlying tooth is still prone to decay and gum disease.
Ceramic on the surface may chip or fracture. Avoid chewing excessively-hard substances like ice or bones. 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.
Regular check-ups will enable your dentist to detect any problems with your crown and recommend necessary treatment.

INLAYS AND ONLAYS
Inlays are restorations usually placed on the chewing surfaces of the back teeth.
An inlay fits within the confines of the teeth. An onlay covers the entire chewing surface of the tooth. These can be made of either plastic resin or porcelain.
The procedure involves removing decayed tooth structure or old fillings, preparing the tooth cavity, taking an impression of the cavity to fabricate a custom-fit inlay or onlay. Two visits are required to complete the treatment.
