What is Mouth Ulcers (Canker Sores)?
Mouth ulcers, also known as canker sores or aphthous ulcers, are small, painful lesions that develop on the soft tissues inside the mouth � on the inner cheeks, lips, tongue, gums, or the floor of the mouth. They appear as round or oval sores with a white or yellowish center surrounded by a red, inflamed border.
Most mouth ulcers are minor and heal on their own within 1-2 weeks without treatment. However, they can be extremely uncomfortable, making eating, drinking, and speaking painful. Some people experience recurrent ulcers that keep coming back, which may indicate nutritional deficiencies or immune system issues.

Causes
Understanding the root causes helps in both prevention and determining the right treatment plan. Here are the primary factors that contribute to this condition.
Accidental Biting
Biting the cheek, lip, or tongue while eating is one of the most common triggers for ulcers.
Stress & Anxiety
Emotional stress is a well-documented trigger for recurrent mouth ulcers.
Nutritional Deficiency
Low levels of iron, vitamin B12, zinc, or folic acid are linked to frequent ulcers.
Harsh Toothpaste
Toothpaste containing sodium lauryl sulfate (SLS) can irritate the oral mucosa.
