Procedures of getting a dental crown
It usually requires about 2 visits to the dentist when preparing a tooth for a crown. The first visit involves the dentist preparing and examining the tooth, while the second visit involves the actual placement of the permanent crown.
During the first visit, the dentist performs an X-ray. The significance of this is to check the roots of the tooth that will receive the crown and neighboring areas. In some cases some materials are removed to create space for the crown.
The first thing the dentist does before the crowning process begins is to anesthetize (numb) the tooth and the gum tissue around the tooth. To make room for the crown, the tooth the crown will be placed on is filed down along the chewing surface and sides.
The type of crown that will be used will determine the amount that will be removed. If a large area of the tooth is missing due to damage or decay, the dentist uses filling material to build up the tooth to support the crown.
