Crowns are a restorative procedure for teeth that are considerably broken down from either old failing restorations, decay, or broken off tooth structures. They cover the remaining tooth and restore the shape and function.
However, gold is the preferred choice for a molar that does not appear when a person smiles.
Porcelain makes a crown look almost indistinguishable from a natural tooth. The gold part, which is located below the porcelain, helps give strength to the tooth. Porcelain itself is very strong, but not as strong as gold and can fracture. This type of crown is fabricated in a laboratory following an impression of the tooth, and a temporary crown is needed during the fabrication period.
They can also be used in higher stress areas like back teeth (molars). They are not as strong as porcelain fused to gold or all gold crowns.
When restoring your tooth with a crown, the existing tooth is cleaned and reshaped. An impression is then taken followed by a temporary crown. The temporary crown will work and look reasonably well while the real crown is made in the dental laboratory. At your next appointment the real crown will be cemented onto your existing tooth.
