Ankyloglossia and other oral ties have been recognized for centuries, but interest in and literature on these topics has recently increased. This article presents the latest evidence on the diagnosis and management of tongue-tie and outlines some of the controversies and gaps in the existing evidence. Anterior tongue-tie is accepted in most clinical practices as a potential risk for breastfeeding difficulty, and good evidence exists that division of an anterior tongue-tie leads to improved breastfeeding outcomes. Posterior tongue ties and upper lip-ties are being studied more intensively to provide sound, evidence-based recommendations on their diagnosis and treatment.
