A dental crown is a tooth-shaped cap placed over a tooth. The procedure is performed in 2 stages. The first stage involves using X-rays to check the roots of the tooth and its surrounding bone. Then, the tooth is filed down along the chewing surface and sides. A paste or putty is used to make an impression of the tooth to receive the crown. The impressions are sent to a dental lab where the crown will be manufactured. During this time, a temporary crown is used to cover and protect the prepared tooth. The second stage involves the removal of the temporary crown and the new crown is permanently cemented in place.
