A "PERIODONTIST" is a dental specialist who looks after your gums and other supporting structures of the teeth. Teeth are embedded in a bony socket in the upper and lower jaw bones, known as the maxilla and mandible respectively. The roots of the teeth, which are embedded in the bone, are coated with a substance known as the cementum. This cementum unites the teeth to the bone with the help of a shock absorbing ligament known as the periodontal ligament.
