Patient: How to treat recurrent oral ulcers? Han Jinyou, Department of Stomatology, Liaocheng People’s Hospital: Recurrent oral ulcers are the most common clinical oral mucosal disease with a prevalence of 10-30%, regardless of age and gender. There are three clinical types: mild stomatitis, inflammatory stomatitis, and periglandular stomatitis. Because the etiology is unknown, its treatment is mainly a combination of removing the causative factors, treating related diseases, vitamin supplementation, enhancing immunity, local anti-inflammatory symptomatic treatment and avoiding mental tension and reducing fatigue. For mouth ulcers that do not heal, you should go to the hospital in time for examination and, if necessary, pathological examination to make a clear diagnosis and then give the appropriate treatment. Since your condition is described too simply, we suggest you go to the Department of Oral Medicine or the Department of Mucosal Diseases of Bin Medical Hospital for consultation and treatment.
