Crowns function as full coverage restorations that cover a tooth that is likely to break. These are most commonly done after a root canal treatment or when a filling wears out. The larger a hole made by a cavity, the more likely it is that a crown will be required. Crowns help to prevent teeth from cracking and aid in creating a nice smile.
It will take two appointments to restore a tooth with a crown. On the first day any decay is removed and shaped to accept the crown. Following this, an impression is made to fabricate a crown. Crowns are typically made of high-strength porcelain, gold alloys, all ceramic materials or gold. During the intermittent period between the first and second appointment, a temporary crown can be worn.
