Dental Crowns Explained
A crown, also known as a “cap”, is a porcelain or gold shell that fits over a tooth to restore its esthetic and functional performance. Crowns are made from a variety of materials including porcelain and metal – usually a gold alloy. Each material has relative benefits and drawbacks, balancing strength and esthetics. In visible areas, porcelain is typically used. In minimally visible areas, gold crowns may also be used. Crowns are required for broken or fractured teeth, decayed teeth, teeth with root canals, large filling replacements, or cosmetic enhancement.
Crowns provide a durable restoration for a tooth, but like all dental work (and teeth!) they may eventually need to be replaced.
What does getting a crown involve?
The procedure for a crown usually involves two appointments. At the first appointment, any decay or old filling material is removed, then the tooth is shaped and an impression is taken to provide a mold to the dental laboratory. The patient is provided with a temporary crown, that remains until the second appointment. At this time, the temporary crown is removed and the new crown carefully fitted. When the crown has been cemented in place, there is often pressure from adjacent teeth. The bite should feel comfortable and within an hour the crown should be unnoticeable. Crowns are maintained through regular brushing and flossing, and with regular check-ups. Just like natural teeth, crowns are for chewing food, not tools for opening and cutting things. Excessive force can chip or crack crowns and natural teeth alike.
