Drooling in children with neurological dysfunction indicates neurogenic failure to coordinate the muscles of the tongue, soft palate, and face which act in the first stage of swallowing. This causes excessive pooling of saliva in the anterior part of the mouth and consequent overspill. Treatment for drooling includes behavioral, pharmacological, and surgical modalities. Correcting a malocclusion has also been reported to help eliminate drooling. This paper describes the treatment of a child with neurofibromatosis, psychomotor, developmental, and neurologic retardation, and difficulty with speech. The patient was referred to our clinic to correct his drooling. Simple orthodontic treatment succeeded in eliminating the drooling and improving his speech.
