Direct restoration of a tooth with an irregular shape

A peg-shaped tooth is the most common anomaly in tooth shape. The patient, a 16-year-old young man, complained about his peg-shaped lateral incisors. The patient is dissatisfied with his smile, especially the anomaly of tooth 2.2. Since the patient and his family came to the city only for treatment, it must be completed in one visit. Considering the patient's age, the choice was made for direct composite restoration without preparation. A night guard is recommended for the patient.

Peg-shaped teeth

Peg-shaped teeth are a fairly common occurrence that we encounter. Orthodontic treatment alone is not sufficient in such cases. There are many methods to restore the shape of the tooth. Some of them can damage soft tissues. In minimally invasive dentistry, we prefer direct restorations, which usually allow treatment in a single visit without preparation.
