Successful treatment of self-inflicted tongue trauma patient using a special oral appliance

A 7-year-old male presented with a painful ulcerative lesion on the right lateral tongue and left lower buccal mucosa due to self-inflicted trauma. Antibiotic medication and use of a mouthwash agent were not effective. We made a special oral appliance to cover the maxillary arch and teeth to protect the tongue. The patient showed immediate improvement and did not suffer from any complications. Invasive procedures such as biopsy were not needed. We believe that accurate clinical diagnosis is important and treatment with an oral appliance is effective in self-inflicted oral trauma in children.
