Gingival hyperplasia or enlargement is usually a secondary manifestation of underlying systemic diseases or drug induced or part of a syndrome. In certain cases if the causative factors of gingival enlargement are unknown, then it should be categorized as idiopathic gingival hyperplasia. We are presenting a case report of idiopathic gingival hyperplasia with the chief complaints of generalized gingival hyperplasia with supernumerary teeth mimicking Zimmermann Laband syndrome. The management of patients with idiopathic gingival hyperplasia should be thoroughly examined to rule out the known cause and blood samples should be taken to exclude blood dyscrasias.
