I often get a mouth ulcer. What is the reason for this?

Hi,

Welcome to icliniq.com.

As per your complaint, you are suffering from recurrent aphthous ulcers which is causing you the eruption of ulcers on the tongue. It can be caused due to a number of reasons like stress, nutritional deficiency (iron, vitamin B12, and Folic acid), hormonal changes, acid reflux, tongue trauma due to some sharp teeth or tongue biting habit, excessive intake of sour and citrus foods, uncontrolled diabetes and other immunocompromised conditions. You need to consult an oral physician or a general dentist in this regard to get evaluated and treated. For aphthous ulcer, you can do warm saline gargles. Gargles with 1:1 solution of Benadryl and milk of magnesia can help. Apply numbing gel over the sore for relief from pain especially during eating. Take a multivitamin tablet for a period of 15 days. Avoid spicy, sour, and acidic foods.
