Some permanent premolars have a projected portion of the tooth structure which is fragile; this kind of premolar is called 'Leong's Premolar'. If the projected portion fractures, the pulp inside the tooth may be infected and becomes necrotic, or even results in formation of abscess.
To avoid the projected portion to fracture, the dentist may carry out the following preventive treatments according to situations:
||Strengthen the projected portion|
||Remove the projected portion and apply filling to the cavity|
If you think you have a Leong's Premolar, you should ask your parents to take you to a dental clinic for a detailed check-up and receive appropriate treatment as soon as possible!
