A crown is a restoration that covers a tooth to restore and protect it. A crown restores a tooth to its natural shape and size and its purpose is to strengthen and/or improve the appearance of a tooth. There are many reasons a crown may be recommended:
*to support a large filling when limited tooth structure is remaining
*to restore a fractured tooth
*to protect a tooth from fracturing
*to cover discolored or grossly misshaped teeth
*to complete and cover a dental implant
Crowns can be made from several different materials. The most commonly used are Gold, Porcelain Fused to Metal and Full Porcelain
Making a crown involves several steps and usually takes two visits. Most important is placing anesthetic and being very comfortable during the approximately one hour procedure. One to one and a half millimeters of your tooth is removed to accommodate for the thickness of the crown. If your tooth has an existing filling part of that material may be left to act as a foundation for the new crown. An impression of the prepared tooth is made an a temporary crown is formed. Following written instructions from your dentist, a dental laboratory technician will make your crown. Your permanent crown will be placed in 2 weeks.
Proper care of your crown will help it last a very long time. A crown itself is very strong but where it meets your natural tooth is susceptible to decay and must be cleaned thoroughly each day. Brushing and daily flossing around your new crown is a must to ensure its longevity.
