A crown is a cap, which covers the whole tooth surface, restoring it to its original shape and size. A crown protects a tooth, preventing tooth fracture. Though there are many kinds of crowns, porcelain (tooth-coloured) crowns are the most popular. They are highly durable and will last a number of years. Porcelain crowns are made to match the shape, size, and color of your teeth.
A crown process customarily requires 2 appointments. After the tooth is numbed, the dentist will prepare the tooth by removing any decay, old filling material, and shaping the surface to correctly fit crown. Then several highly accurate moulds (or impressions) will be taken and used to make your custom crown. A mould will also be used to make a temporary crown, which will stay on your tooth for approximately two weeks until your new permanent crown is fabricated by a dental lab technician.
