What are Crowns?
A dental crown, is a dental cap for the tooth which is made of porcelain or metal, which covers the tooth to improve its shape, size, strength, or to improve its appearance. If left on its own, the tooth usually is at some risk, with considerable damage that needs to be stopped to keep the tooth strong.
However, sometimes a healthy tooth needs to be crowned in order to adapt a dental appliance to it for stability. This is the case with partial dental plates and to replace missing single teeth by attaching a replacement tooth to the adjoining teeth. Crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies above the gum line.
