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 (tooth-colored) crowns are the most popular, because they resemble your natural teeth. They are highly durable and will last many years but, like most dental restorations, they may eventually need to be replaced. Porcelain crowns are made to match the shape, size, and color of 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
• The tooth has a root canal
A dental bridge is a fixed (non-removable) appliance and is an excellent way to replace missing teeth.
There are several types of bridges. You and your dentist will discuss the best options for your particular case. The “traditional bridge” is the most popular type and is usually made of porcelain fused to metal. Porcelain fixed bridges are most popular because they resemble your natural teeth. This type of bridge consists 0f two crowns that go over two anchoring teeth (abutment teeth) and are attached to pontics (artificial teeth), filling the gap created by one or more missing teeth.
Dental bridges are highly durable and will last many years; however, they may need replacement or need to be re-cemented due to normal wear.
Reasons for a Fixed Bridge:
Fill the space of missing teeth, maintain facial shape, prevent remaining teeth from drifting out of position, restore chewing and speaking ability, restore your smile, or upgrade from a removable partial denture to a permanent dental appliance.
