Alterations in tooth shape and size are related to impaired esthetic appearance and facial harmony and can have a negative effect on a patient's self-esteem. Many alternatives for treating peg-shaped teeth are described in the literature. This article presents two clinical cases involving peg-shaped lateral incisors that were transformed with composite resins, addressing aspects related to treatment alternatives and facial esthetics. At a seven-year recall visit, the composite resins were problem-free and the patients remained very happy with the treatment outcome. Composite resin appears to be an adequate alternative to direct treatment options for restoring peg-shaped incisors.
