Crowns

Crowns are used to restore teeth that have been badly damaged or for cosmetic reasons. A crown is a cover made of metal or porcelain, or both, that goes over a damaged or weak tooth. Your dentist will shape the tooth so that the new crown will fit snugly over the prepared tooth.

Preparation time will depend on how damaged the tooth is and whether it needs to be built up with a filling first. The crown is sometimes held in place by a post in the root canal if a lot of the tooth substance is missing. Your dentist will use a soft mouldable material to make an impression of the tooth that is to be crowned and the nearby teeth. A dental technician uses the impression to make the crown the size and shape needed. A temporary crown made of plastic is put over the tooth until the permanent crown is made. You can chew on a temporary crown but it won't be as strong as the finished one.

When the crown is fitted, your dentist will make small adjustments to make sure you can bite comfortably and make sure that you are happy with its appearance. The crown is tried on first, and then glued into place.
