Aphthous stomatitis

Aphthous stomatitis, commonly known as canker sores, is a condition characterized by the recurrent formation of benign, non-contagious mouth ulcers. While the exact cause is not fully understood, it is linked to a T cell-mediated immune response and can be triggered by factors such as nutritional deficiencies, local trauma, stress, and hormonal changes, often healing on their own with symptom relief from gels and mouthwashes.
