<bot>: Hello:)Thank you for choosing Chat Doctor. You did not mention if he is under medication for general health.(Check with the physician reg. This if any). Some Chat Doctor. A clear cause for ulcers has not been given yet, however poor oral hygiene, stress, deficiencies can attribute. He can use a lidocaine based gel like GEMSTONE before food(this makes the area little numb, for temporary relief). Gargle thrice daily with warm saline water. Use a soft tooth brush. Have a tobacco free, non-alcoholic, stress-free lifestyle. Check if any sharp tooth causes this ulcer, if so it should be rounded. Regards.
