A crown is a restoration that completely caps or encircles a tooth or a dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth.They are used to improve the strength or appearance of teeth.
Inlays and Onlays
It is not always necessary to put crowns on broken teeth. Inlays and onlays are a more conservative option, they fit into a tooth similar to a filling, yet they are stronger restorations.
Patients who are missing teeth have an alternative to bridges, partials or full dentures. Implants support restorations that resemble a tooth or group of teeth to replace missing teeth. They are titanium screws that have a root-form and are placed within the bone. Once they are integrated with the surrounding bone, a crown is placed.
Bridges have been successfully replacing missing teeth for years. It is a fixed restoration that joins an artificial tooth to adjacent teeth or dental implants. Preparing a bridge requires shaving the teeth on either side of the missing teeth and adding porcelain crowns to create anchors for the prosthetic device.
Complete and Partial Dentures
Partials are often selected as an inexpensive option over a bridge or dental implant for replacing lost teeth. They are removable which makes them different to bridges. They are for patients who are missing some of their teeth. Complete Dentures are supported by the surrounding soft and hard tissues and replace all missing teeth.
In the past, dentists have been repairing teeth by placing amalgam fillings. Lately, there has been some concerns regarding the mercury vapor released by the amalgam. The American Dental Association, still considers it safe, affordable and durable. Disadvantages do exist, like placing the restoration requires the removal of healthy tooth structure. Also, the waste of the amalgam has to be handled in a special way to protect the environment. Nowadays, composite fillings are the material of choice because of the facility of them to be bonded to the tooth, reducing the removal of tooth structure. Color and shading can be matched to the existing tooth.
