Oral Health Considerations for Geographic Tongue

By Cassandra Penning, RDH, BS, JoAnn Gurenlian, RDH, MS, PhD, AFAAOM, Leciel Bono, RDH-ER, MS


Geographic tongue (GT) is a benign oral mucosal lesion that usually affects the dorsal and lateral surfaces of the tongue.1 This condition was first described by Rayer2 in 1831 as a wandering rash of the tongue, and has since been known by other names including benign migratory glossitis, erythema migrans, and annulus migrans.3 The disease is characterized by alternating activity, remission, and reactivation at various locations of the tongue. This article will review the clinical features of GT, etiology and pathogenesis, treatment, and oral health considerations. A clinical case of GT will be presented to familiarize oral health professionals with this unique pathosis.
