The advancement of surgical procedures for gingival repair and restorative treatments for anterior teeth, which stand out in the scientific community, has been fundamentally influenced by the pursuit of aesthetics. The purpose of the current study is to describe the clinical behaviour of a patient who has small teeth and a gummy smile. The goal was to use a clinical case to illustrate how anterior cosmetic rehabilitation, which includes gingivectomy and composite resin veneers, can be accomplished. The restoration of anterior teeth involves using better shades, colours, opacities, translucency, and anatomical onformation, while treatments that combine dentistry and periodontics are capable of producing good results, enabling normalisation of the gums, correcting their deformities, and restoring the interdental grooves and papillae. Periodontal surgery called a gingivectomy involves removing extra gum tissue. The purpose of the procedure is to change the tooth’s contour, which generates an increase in the clinical crown, providing a smile with adequate protection and support for the oral environment. Resin veneers or direct restoration on anterior teeth are the dental remodelling treatment that guarantees longevity and satisfactory results, in addition to being minimally invasive. The adhesive systems and composite resins available are of high quality, do not impose aesthetic limits, and allow a natural effect determined by the excellence and technical knowledge of the operator. The plan accomplishment allowed reaching the aesthetic principles and establishing a better contour shape and size, both of the gingival tissue and of the anterior teeth. Thus, the procedure was always performed prioritising the demands and satisfaction of the patient, generating excellent clinical results.
