Hello, Welcome to Chat Doctor forum. Recurrent ulcers on tongue usually occurs due to-poor oral hygiene, vitamin deficiency, intake of too much of spicy, allergic foods. I would advise you to maintain oral hygiene well. Avoid smoking, spicy foods. Usually corticosteroids along with vitamin B complex tablets has to be administered. If symptoms persists, please do visit a dentist. Take care.
