Porcelain Crowns

When large fillings are present in the mouth, particularly if you grind your teeth or even in the act of normal chewing over time, this can allow teeth to become cracked or fractured. When cracks become extremely large, the dentist may decide that the patient is in need of a root canal or even at the point where the tooth will need to be extracted.  But in some cases, certain patients may benefit from the placement of a dental crown instead. A crown is a permanent dental restoration that seals the entire tooth and recreates the natural tooth enamel to give an extra layer of protection against premature loss or damage. Crowns cover the entire tooth, or in some cases can be used to cover an implant. They are created to look exactly like a normal tooth and will blend in seamlessly with your smile. Crowns are fabricated by using x-rays, pictures of the teeth, and impressions of the mouth.
 
There are several types of dental crowns.  The most is the ceramic or porcelain because it is the most natural looking type of crown and it’s also very durable. As with any dental work though, over the course of time, they may need to be replaced.
 
Why might a patient need a crown? Here are some common scenarios:
 
* To fix a fractured or broken tooth
* To increase the aesthetic appearance of your teeth or smile
* To address areas of decay in the mouth
* To fix broken fillings
* To prevent future damage from extremely large fillings
* As part of root canal therapy
 
The process of getting a dental crown usually requires at least two dental visits. The first appointment is when the dentist will prepare the natural tooth for the crown.  They start by removing a significant amount of tooth enamel from around the tooth’s structure. Custom molds called impressions are taken and sent to the dental laboratory.  The lab will then be responsible for the fabrication of the final crown. The same mold is used in the dental office to create a temporary crown that is bonded over the existing tooth.  This temporary tooth will stay in place until the final crown is sent to the office from the lab.  Once the final crown is received by the dentist, the patient will return so that the temporary crown can be removed and the final crown fitted and cemented into place.  Your dentist in Bristol, VA will also make sure that the patient’s spacing and bite are still accurate with the new crown in place.
