Understanding Canker Sores
Canker sores, also known as aphthous ulcers, are small, painful sores that can occur inside your mouth, on your tongue, lips, or cheeks. They are not contagious and usually heal on their own within one to two weeks. Canker sores are often round or oval with a white or yellowish center and a red, inflamed border. While the exact cause of canker sores is unknown, certain factors can contribute to their development.
Causes of Canker Sores
The exact cause of canker sores remains unknown, but several factors are believed to contribute to their occurrence. Some common triggers include injury or trauma to the mouth tissues, such as accidental biting, dental procedures, or rough toothbrushing. Hormonal changes, certain medications, and underlying medical conditions like autoimmune diseases or nutritional deficiencies can also increase the risk of developing canker sores.

Symptoms of Canker Sores
The primary symptom of canker sores is a painful sore inside your mouth. Other common symptoms include a tingling or burning sensation before the sore develops, difficulty in eating or drinking, swollen lymph nodes, and a general feeling of discomfort. Canker sores can vary in size and can occur as a single sore or in a cluster. It’s important to note that if you experience any unusual symptoms or severe pain, it’s best to seek medical advice.
