Canker sores, what to do if they are getting bigger now?

Canker sores are a common oral disease that usually presents as small, superficial sores on the oral mucosa. Seek medical attention if mouth sores are:

1. Large ulcer area: mouth ulcers with a diameter of more than 2 cm or multiple ulcers occur at the same time.

2. Long duration of ulcers: mouth sores persist for more than two weeks and do not heal.

3. Ulcers accompanied by other symptoms: such as severe pain, fever, swollen lymph nodes, etc.

4. Recurrent canker sores: At least two or more episodes of canker sores per year.

While you wait to see your doctor, you can take the following steps to relieve symptoms and promote healing:

1. Practice good oral hygiene: Use a soft-bristled toothbrush to gently clean your mouth when brushing your teeth and rinse your mouth to reduce the risk of bacterial infections.

2. Avoid irritants: Avoid eating excessively hot, cold, and spicy foods and drinks to avoid irritating the wound.

3. Use of topical medications: Lozenges or sprays containing ingredients such as benzalkonium chloride or hydrocortisone can be purchased in pharmacies for local anti-inflammatory pain relief.

4. Vitamin B supplementation: Canker sores are associated with malnutrition, and supplementing with foods rich in vitamin B complexes or oral vitamin B supplements can help speed up healing.

Further examination and treatment under the guidance of a professional physician is necessary. Please make an appointment with a dental specialist as soon as possible and receive an appropriate treatment plan.
