A crown (or cap) is a covering that encases the entire tooth surface restoring it to its original shape and size. A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations.
Although there are several types of crowns, porcelain or zirconia (tooth colored crown) are the most popular, because they resemble your natural teeth. They are highly durable and will last many years, but like all dental restorations, they may eventually need to be replaced. Porcelain and zirconia crowns are made to match the shape, size, and color or your teeth giving you a natural, long-lasting beautiful smile.
Reasons for crowns:
- Broken or fractured teeth.
- Cosmetic enhancement.
- Decayed teeth.
- Fractured fillings.
- Large fillings.
- Tooth (especially a back tooth) has a root canal.
What does getting a crown involve?
A crown procedure usually requires two appointments, one long and one short.
At your first appointment, while the tooth is numb, the dentist will prepare the tooth by removing any decay and shaping the surface to properly fit the crown. Once these details are accomplished, your temporary crown will be placed with temporary cement and your bite will be checked to ensure you are biting properly. Highly accurate molds (or impressions) will be taken in order to create your custom crown. A mold will also be used to create a temporary crown which will stay on your tooth for 2-3 weeks until your new crown is fabricated by a dental laboratory.
At your second appointment your temporary crown will be removed, the tooth will be cleaned, and your new crown will be carefully placed to ensure the spacing and bite are accurate.
You will be given care instructions and encouraged to have regular dental visits to check your new crown.
