Oral ulcers are a very frequent complaint of patients reporting to dental professionals, of which traumatic ulcers are the most common They are very painful and troublesome while the patient speaks, masticates, or brushes. Various treatment modalities, such as topical analgesics and topical or systemic antibiotics, are used conventionally.
