A crown may be used to protect a cracked tooth, or to restore functionality to a tooth with excessive decay, a root canal, or a pre-existing crown.
During a crown procedure, your dentist prepares the tooth and makes a molded impression to send to a dental lab. A temporary crown is created during your visit to protect the tooth while your permanent crown is being fabricated. This process usually takes 2 weeks, then you return to have your permanent crown cemented.
How long do crowns last? The average crown lasts 12 years but can last much longer with good oral hygiene, regular cleanings, and for those of you who grind your teeth-a mouthguard. However, even insurance companies recognize the need to have them replaced more often. On average, insurance will pay to have a crown replaced every 5-7 years.
Another common question is, “Why does my crown need to be replaced?” Reasons include: the tooth has formed decay at the edge of the crown; the crown has become worn excessively; the crown has broken; or the esthetics of the crown have become objectionable – which means the crowns edge has become visible, or the color of the crown does not match the adjacent teeth. As always, good homecare increases the longevity of all dental restorations.
Permanent crowns can be made from all metal, porcelain fused to metal, or all ceramic. We proudly offer CEREC restorations using CAD-CAM technology. CEREC restorations eliminate the need for a temporary crown or a return visit for the final cementation.
