Canker Sores

Possibly caused by issues with a person's immune system, canker sores can develop in several places, including inside the cheeks, gums, lips, tongue and on the roof of the mouth. The round or oval sores are white or yellow with a red border and can be triggered by particular foods, stress and hormonal shifts.1‘Canker Sores (Mouth Ulcers): Overview.’ /[Internet/].

Healing typically takes two weeks. Patients can eat bland foods in the meantime to avoid irritation, and dentists sometimes prescribe a pain killing gel.
