Infolding of the inner enamel epithelium and Hertwig’s epithelial root sheath create a groove called as Labiogingival groove which extends to a varying depth into root. It is basically a congenital dental anomaly. The aim of this report is to present the management of a case affecting periodontal attachment apparatus due to the presence of a labiogingival groove. A 30-year-old male reported with the complaint of dull, gnawing, intermittent pain along with pus discharge with respect to upper front teeth since 3 months. Intraoral examination revealed purulent discharge to maxillary left central incisor. A provisional diagnosis of localized gingival abscess in relation to maxillary left central incisor was given, and required surgical procedure was carried out. A labiogingival groove was noticed on exposure of tooth which could have been a contributing factor for the progression of the condition. Keywords: Labiogingival groove, periodontitis, dental plaque
