If your smile is in need of a makeover, crowns can provide predictable results. Crowns can give an unattractive tooth back its beautiful shape and color. For smaller or worn down teeth, a crown can restore the natural size of the old tooth. A crown can replace either part of or the tooth's entire crown. For procedures requiring only the areas visible from the outside, a veneer may be an alternative option.
A bridge may be used to replace a single tooth. A bridge consists of both a false tooth, called a pontic, and the anchors (abutment crowns) that support the pontic. The entire structure spans the space vacated by the missing tooth.
Neighboring tooth structure is removed shaping them to receive an anchor crown. An impression is then taken and sent to a dental lab where they fabricate the bridge.
The structure part of the bridge is created with a strong metal alloy that can handle the anticipated stresses.
Tooth-like porcelain is then fused to the structure. Once the bridge is tested for a correct fit, the anchor crowns are cemented to the neighboring teeth.
Dr. Coyle will be happy to discuss the many types of crowns available today.
There are three basic types of crowns:
1) Porcelain outer surface with a metal base crown.
2) Pure porcelain or composite crown.
3) All metal crown, which is usually gold.
They all differ in durability, strength, appearance and cost.
