Dentists Explain the Cause of Canker Sores (and How to Fix It)

Mouth ulcers, also known as canker sores, are small, painful sores inside the mouth that can appear on the tongue, gums, lips, or inner cheeks. They are usually white or yellow with a red border and can be triggered by stress, injury, certain foods, or nutritional deficiencies. Most heal within 1–2 weeks, but persistent or recurring ulcers should be checked by a doctor. Simple remedies like saltwater rinses, gentle oral care, and avoiding irritants can help relieve discomfort. #MouthUlcers #Cank
