Post and Core is a type of dental restoration used either to stabilize a weakened tooth or provide an anchor for a crown. Post and Core is utilized when inadequate tooth structure remains to support a traditional restoration, it consists of the insertion of a small rod, known as Post, into the root space of an affected teeth, leaving several millimeters protruding. Post and core treatment is recommended for teeth which are severely decayed or structurally damaged. After a root canal treatment, the post is positioned in the root of the tooth. It can be used to support a filling or to hold a crown. While some posts are ready made, others are made in the laboratory especially to fit the teeth. There are two types of post and core namely prefabricated post and cast post. A prefabricated post is quicker to fit as there is no extra laboratory work needed and they come in various shapes and sizes. A cast post may be used in the cases where a prefabricated post is not suitable. The dental post and core takes about 1 to 3 hours and the initial treatment where the post and build up is fitted takes around an hour. After the treatment, the patients should avoid eating on the crown and some minor discomfort can be expected after the treatment.
