Dental crowns are used by dentists for many reasons. Most often they are placed to give strength to teeth weakened by large fillings or previously root canaled. Due to their vulnerable state these teeth are more susceptible to breaking or cracking and placing a crown on them gives them back strength.

Crowns may also be temporary or permanent, depending on how long they are needed to protect the teeth. Permanent crowns are often created in a dental lab and made of a highly durable material. They are cemented to the tooth and very durable, restoring the look, feel, and function of the teeth. Temporary crowns are designed in a dental office and can be used to protect the tooth in preparation for another treatment, including while permanent crowns are being created.
