Management of Recurrent Gummy Smile After 7 Years: A Case Report

Abstract

Esthetic crown lengthening is a periodontal surgical procedure to correct excess gingival display (ie, "gummy smile"). The procedure may require soft-tissue excision only, osseous resection, or a combination of both. However, the long-term healing responses, such as soft-tissue relapse or recession and hard-tissue regrowth and resorption, have not been fully reported in the literature. This case report describes the management of a patient with esthetic concerns about a gummy smile. The patient stated that the maxillary anterior area had been previously treated with periodontal surgery 7 years earlier but the condition had slowly recurred over time. The authors highlight the possible reasons for the recurrence and the keys to successfully managing the case.
