The tooth and its supporting structures should be viewed as one biologic unit. An understanding of the periodontal-restorative relationship is necessary for the proper form, function, and esthetics of restoration and comfort to the patient. The dimension of the space that the healthy gingival tissue occupies above the alveolar crest is known as the biologic width. The concept of biologic width gains importance in the case of extensive caries management, subgingival margin placement, crown/root fractures, orthodontic banding, subgingival perforation and post, and core placement in endodontic therapy. Biologic width is important for the preservation of periodontal health which eventually decides the success of restorative procedures. This article discusses the anatomy, categories, evaluation, violation, and methods to correct the violation of biologic width.
