Crowns :
involve completely covering the existing tooth with custom
made teeth of porcelain or a combination of porcelain and
metal. It's also necessary to shave all around the outer
portion of the natural tooth. This method requires local
anesthesia and usually takes two or more visits. This is
generally recommended when teeth are weak , have large
fillings or when teeth are missing. This process is not
usually done just for cosmetic purposes on healthy, strong
teeth.
