Mucosal fenestrations are rarely encountered in clinical practice, and as such their management is not often reported. Their treatment might be further complicated due to a communication with the oral environment, making them more susceptible to accumulation of debris, plaque, and calculus, thereby reducing the probability of mucosal renewal. The aim of the present case report is to highlight one such rare clinical scenario and its apt and effective management. Surgical management of an uncommon presentation of concomitant gingival recession with an isolated mucosal fenestration in an atypical location, with an allograft matrix is presented here with 2 years' follow-up. A review of the literature reveals no previous application of AlloDerm graft for the management of a similar situation.
