When large fillings are present, they can still allow teeth to become fractured following grinding or chewing. When cracks are extremely large, the dentist may decide that the patient is a candidate for root canal therapy or may be at a point where extraction is necessary. Other patients may benefit from the placement of a dental crown. A crown is a permanent restoration that recreates the natural tooth enamel to seal the entire tooth, giving it an extra layer of protection against premature loss or damage. Crowns cover the entire tooth or implant and blend in seamlessly with your own smile. Crowns are fabricated to look completely natural and are fabricated with the help of x-rays, photographs, and impressions of the natural teeth.
There are several variations of dental crowns, though the most popular is the ceramic crown. These are natural-looking and are extremely durable. Over time, however, they may need to be replaced.
There are many reasons why patients may need crowns. They include:
* Fractured or broken teeth
* Aesthetic enhancement
* Large areas of decay
* Broken fillings
* Extremely large fillings
* Root canal therapy
Getting a dental crown fabricated and placed typically requires at least two dental visits. The first appointment is the time the dentist will prepare the natural tooth with the removal of a significant amount of enamel surrounding the tooth structure. Accurate molds called impressions are done and sent to a dental laboratory for the fabrication of the final crown. This same model is used to create a temporary crown that is bonded in place until the final one is returned to the dental office. Once the dentist receives the completed crown, patients come back into the dental office for the removal of their temporary crown and the fitting and cementing of their final restoration. The dentist will ensure that the spacing and bite are still accurate following placement.
