Mouth ulcers are small, painful sores that appear inside the mouth. Most ulcers are caused by minor trauma, such as accidental biting of the cheek, sharp edges of teeth, or irritation from dental appliances. They generally heal on their own within one to two weeks without specific medical treatment. During this period, it is helpful to avoid spicy or acidic foods that can increase discomfort.
While most ulcers are harmless, some may indicate underlying health issues. Recurrent ulcers could be linked to nutritional deficiencies, particularly a lack of vitamin B12, iron, or folic acid. Stress and hormonal changes can also trigger these sores in some individuals. If ulcers appear frequently or in large numbers, it is advisable to consult a dental professional to rule out systemic causes.
There are specific warning signs that require immediate attention. If a mouth ulcer is unusually large, persists for more than three weeks, or is painless, it must be examined by a registered dentist. Other concerning symptoms include ulcers that bleed or are accompanied by a high fever. Early assessment is crucial to ensure that more serious conditions are not overlooked.
Managing mouth ulcers involves maintaining good oral hygiene despite the discomfort. Using a soft-bristled toothbrush and avoiding harsh mouthwashes can help prevent further irritation. If pain is severe, a dentist may recommend protective gels to coat the ulcer. Regular dental check-ups allow for the early detection of sharp tooth surfaces that might be causing repeated injury to the delicate mouth lining.
