A. Being tongue-tied means your child's frenulum (the membrane that attaches the tongue to the floor of the mouth) is too short, which interferes with proper movement and mobility of the tongue. Some kids with tongue-tie can talk normally, but many have trouble with certain sounds. The best thing to do is take your child to an ENT (ear, nose, and throat specialist); he or she will assess whether it would be appropriate to clip the frenulum (a simple in-office procedure) to free up the tongue and improve speech. Sometimes the procedure works immediately and the child speaks clearly almost overnight, but in other cases, some speech therapy is needed to help your child adjust and improve on any language skills he may be lacking because of the problem.
