They are typically utilized when the tooth in question has a large broken area, or a large filling with cracks or decay in the remaining tooth structure. They can also be used to hold a tooth together that has symptoms of a crack where there is pain on biting pressure or release of biting pressure. They are also highly recommended on any tooth with a root canal since they prevent fracture of the underlying tooth structure.
They also can be used in cosmetic dentistry to cover discolored tooth structure, replace missing tooth structure, straighten teeth, or close gaps in between teeth. They are typically bonded to the tooth using a dental cement. Crowns can be made from many materials, but at Moorpark Smiles, we typically recommend zirconium for its durability and resistance to fracture, especially for back teeth. On front teeth, we may recommend lithium disilicate.
The most common method of crowning a tooth involves using a dental impression of a prepared tooth by your dentist to fabricate the crown at the lab. The crown can then be inserted at a subsequent dental appointment. Using this indirect method of tooth restoration allows use of strong restorative materials such as zirconium which require many hours of fabrication time time, intense heat, such as sintering which would not be possible in a dental office.
