A porcelain crown is a cap-like structure that is permanently bonded to a particular tooth to provide superior aesthetics and function. Sometimes crowns are referred to as caps.
Porcelain crowns are a very effective way of providing patients with their desired cosmetic result, while at the same time strengthening the tooth structure. A crown fits over the remaining part of a prepared tooth, making it strong and giving it the shape of a natural tooth. Crowns can be used on almost any teeth and, if properly maintained, can last for well over 10+ years.
Crowns can be used, both aesthetically and functionally, in restorations with:
- Heavily repaired or broken teeth
- Badly discoloured large fillings
- Protecting the physical integrity of a tooth after a root canal procedure.
A bridge, is used to replace a missing tooth by joining permanently to adjacent teeth or dental implants. Conventionally, bridges are made using the indirect method of restoration. However, "bridges can be fabricated directly in the mouth using such materials as composite resin".
