Crowns are sometimes also known as ‘caps’, and are an ideal way to rebuild teeth which have been broken, or have been weakened by decay or a very large filling, or otherwise, a root-treated tooth. The crown fits right over the remaining part of the tooth, making it strong and giving it the shape and contour of a natural tooth.
At your first appointment the dentist will prepare the tooth to the ideal shape for the crown. This will mean removing some of the outer surface, and leaving a strong inner ‘core’. The amount of the tooth removed will be the same as the thickness of the crown to be fitted.
Once the tooth is shaped, the dentist will take an impression of the prepared tooth, one of the opposite jaw and possibly another to mark the way you bite together. The dentist will then create a temporary crown whilst your impressions are sent off to the lab technician, along with any other information they need to make the permanent crown.
The permanent crown will be made to match the shade of the rest of your teeth exactly; this will then be fitted on your second visit.
Once the fit and appearance of the crown has been checked – and approved by you – it will be cemented in place with special dental cement. The cement also forms a seal to help hold it firmly in place.
