Recurrent Tongue Ulcers — Which Doctor Should I See?

Common causes include minor injuries from dental work or sharp foods, nutritional deficiencies (B12, zinc, folate), stress, certain medications, viral infections, or oral conditions like aphthous stomatitis. Some autoimmune diseases can also trigger them.

Seek medical attention if ulcers are very large, extremely painful, persist beyond 3 weeks, occur frequently, interfere with eating/drinking, or are accompanied by fever or swollen lymph nodes. These may indicate underlying conditions needing treatment.

Avoid irritating foods, practice good oral hygiene, use a soft toothbrush, manage stress, ensure adequate nutrition, avoid mouth injuries, and limit spicy/acidic foods. Staying hydrated and using protective mouthwash may also help reduce occurrence.
