A dental crown fits over or caps a tooth, which results in the appearance of a natural tooth. A number of different materials can be selected to form a crown, such as ceramics, metals and porcelain. A mixture of materials can also be used. A dental crown may be necessary to:
1. Protect a tooth weakened by decay or one that is cracked
2. Restore a tooth that is severely worn down or broken
3. Keep a dental bridge in place
4. Support and cover teeth with large fillings when not much tooth remains
5. Cover severely discolored or misshapen teeth
6. Cover dental implants
Metals are a common material for crowns and can include base-metal alloys, gold alloys and palladium alloys. When metal crowns are used, the crown requires less tooth structure to be removed. Metal crowns will rarely break or chip. The main drawback to metal crowns is the metallic color, but this is not a concern when the crown will not be visible.
Porcelain can be fused to metal and color-matched to nearby teeth. Porcelain crowns are most frequently used for front or back teeth. Ceramic crowns offer the most natural color match when compared to other types of crowns.
Preparing a Tooth for a Crown
In order to create a crown, two office visits are usually necessary. First, the teeth must be reshaped to enable the proper fitting of the crown. An impression will be taken of the tooth during the first visit, and a temporary crown will be put into place. Impressions made during the first visit are sent to a lab where the crown will be made. Crowns are usually ready in two or three weeks. The second visit is when the actual crown is fitted.
Fortunately, if your schedule does not permit this two-visit treatment, then our office also offers CEREC treatment, where you can get your crown in a single day.
What is a Post?
A post is required for teeth that have had a root canal. The post creates a structure for the crown to be supported by. Posts are usually made from metal or plastic.
How Long Do Dental Crowns Last?
Dental crowns can last between 5 and 15 years on average. A crown’s lifespan is dependent upon how much wear and tear it undergoes, the patient’s oral hygiene practices and whether they grind their teeth or bite their fingernails.
