Crowns are full-coverage reformations used to cover individual teeth likely to break or have broken beyond repair by dental fillings. These repairs are most commonly needed after a root canal treatment or when a large filling wears out. The larger the hole made by a cavity, the more likely a crown will be required. Â Crowns, like caps, are fitted over the weakened tooth after dental work. The tooth and crown provide strength and protect the capped tooth and surrounding teeth against more breakage.
Crowns are made of gold, porcelain/metal combination, and complete porcelain. Each material has its pros and cons and advantages in certain situations. The most common choice of material picked for cosmetic reasons is either porcelain with metal or all-porcelain crowns. This process generally takes two appointments to restore a tooth with a crown. During the space of the two appointments, a temporary crown is worn.
