The case of sublingual ulceration associated with erupted primary mandibular incisors in a 1-year-old child is presented. Sublingual ulceration is termed as Riga-Fede disease if the patient is less than 2 years old. Generally, the treatment methods for Riga-Fede’s disease are discing and extraction of the traumatised teeth. Here, the child was treated with photo-polymerised composite resin coverage of the incisal edges of erupted mandibular incisors. The photo-polymerised resin coverage proved to help in the rapid healing of the ulcerations.
