A crown (or cap) is a synthetic covering that covers the entire damaged 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, non-metallic porcelain being the most popular because they resemble your natural teeth. They are highly durable and will last many years, but like most dental restorations, they will eventually need to be replaced. Porcelain crowns are made to match the shape, size, and color or your teeth giving you a natural, long-lasting beautiful smile.
Why would I need a Dental Crown?
- The tooth may be damaged.
- You may have stained or deteriorating fillings.
- You may have had a root canal which will may require a crown.
- Your teeth have been damaged by any unfortunate accident.
Types of Dental Crowns
There are different types of dental crowns:
Ceramic — These are typically used for restoring front teeth, and are popular for their ability to naturally blend with your tooth color. The crown is made of a porcelain-based material.
Porcelain-fused to metal – This crown provides a stronger bond than regular porcelain because it is connected to a metal structure, and extremely durable.
Gold alloys – This crown is a mix of gold, copper and other metals. In addition to providing a strong bond to the tooth, it doesn't fracture, nor does it wear away the tooth itself.
What is the procedure for placing a crown?
The procedure for placing a crown typically requires two appointments. Your first appointment will include taking several highly accurate molds (or impressions) that will be used to create your custom crown. A mold will also be used to create a temporary crown placement which will stay on your tooth for approximately two to three weeks until your new crown is fabricated.
While the tooth is numb, the dentist will prepare the tooth by removing any decay and smoothing the tooth to properly fit the crown. Once completed, your temporary crown will be placed with a bonding adhesive and your bite alignment will be checked.
At your follow-up appointment the temporary crown will be removed, the tooth will be cleaned, and your new crown will be carefully placed with bonding material to ensure the spacing and bite are accurate.
