Dental crowns cover and support a tooth when there is not enough tooth structure to retain and support a filling. A crown covers a compromised tooth and actually strengthens it. Dental crowns can also be used to protect a tooth that is about to break, protect a root canal treated tooth, or be attached to bridge or an implant.
A dental bridge replaces missing teeth by attaching crowns to the surrounding teeth. Fixed bridges are attached directly to the adjacent teeth. Removable bridges are used to replace many missing teeth in one arch. Implant bridges attach directly to dental implants that have been surgically placed in the jawbone, under the gum tissue. The longevity of the dental bridge depends upon its foundation, effective home care, regular check-ups, and maintenance.
Dentistry has a remarkable history of successful repair and replacement of teeth. Although many crowns & bridges have an excellent long-term prognosis, nothing can truly replace your original teeth.
