A mouth ulcer that does not heal after two weeks requires urgent evaluation by a dentist or doctor. Please do not try further self-medication. Persistent ulcers can indicate underlying health issues, including severe nutritional deficiencies, autoimmune conditions, or, in rare cases, oral cancer, which may require a biopsy to diagnose. Avoid spicy, acidic, or hot foods that irritate the ulcer. Your priority should be getting a professional examination to find the exact cause and receive targeted prescription therapy. Please schedule an appointment with a healthcare provider as soon as possible.

Frequent mouth ulcers may occur if the mouth lining is easily irritated or if the body lacks certain nutrients. Try to maintain good oral hygiene and include foods rich in vitamins such as fruits, vegetables, eggs, and whole grains. Avoid biting the inside of the mouth and limit very spicy or acidic foods. If the ulcers keep recurring, consult a doctor to rule out nutritional deficiencies or other causes.
