Leong's Premolar

The difference between a 'Leong's premolar' and a normal premolar is that a 'Leong's premolar' has a projected and fragile portion of tooth structure. If the projected structure fractured and no proper treatment is done,there will be chances for bacteria to infect the pulp of the tooth. The pulp may become necrotic or may even result in periapical abscess. Preventive treatment is needed to protect the tooth from the above situation.

According to individual needs, the dentist will either strengthen the fragile structure, or remove the structure and restore the tooth by composite resin.
