Crowns will be suggested after a posterior tooth has had a root canal treatment, for teeth with a history of cracks or those which are heavily filled or are grossly discoloured. Crowns are like a helmet that covers the tooth and protects it from breaking. They are all white, but some have a metal inner layer for strength.
Implants are false teeth that are attached to a metal post inserted into the jaw. The metal “implant” is placed by a surgeon under local or general anaesthetic. Once the post has healed in the bone and it is firm, a tooth can be attached to the top.
There are other ways of replacing missing teeth such as bridges and dentures. Bridges are where a false tooth is attached to the neighbouring teeth so they are cemented in place and dentures are false teeth that can be removed from the mouth.
