A new therapy for Riga-Fede's disease is reported. It is well-known that the ulceration at the sublingual surface in infants is caused by mechanical stimulation of neonatal teeth or early eruption of anterior deciduous teeth. In many clinics tooth extraction or smo-othing incisal edge was usually performed to remove the stimulation. However, primary denti-tion and occulusion would be influenced by extraction of an anterior deciduous tooth.
In the present case, a soft and long artificial nipple, which is generally used after cleft lip operation, was employed to modify tongue movements during feeding. This method made the tongue movement smaller, and mechanical stimulation to tongue was reduced. After two weeks the ulcer completely disappeared. This therapy seems to be of very simple, effective and conservative approach for treating Riga-Fede's disease.
