Hereditary gingival fibromatosis is a rare benign oral condition which is characterized by slow and progressive enlargement of the maxillary and mandibular arches covering the teeth to various extents. The condition may occur as an isolated disorder or as a part of a syndrome. This condition negatively affects the quality of life. This paper presents a case of 18 year old male with generalized hereditary gingival fibromatosis involving both the dentitions and covering the teeth upto incisal/occlusal third. The excess gingival tissue in this case was removed by sextant wise conventional external bevel gingivectomy under local anaesthesia. The post-operative result was uneventful and the patient’s appearance improved considerably, also improving his mastication, oral hygiene practice and oral health related quality of life as assessed by the reduction in Oral Health Impact Profile (OHIP)-14 scores . After treatment regular recall visits are necessary to evaluate the stability of the treatment.
