Mouth Ulcers
Small sores with a big impact; we help you understand, manage, and heal mouth ulcers with expert care and targeted treatment.
What are Mouth Ulcers?
Mouth ulcers are small, painful sores that develop inside the mouth, such as on the tongue, gums, or inner cheeks. They can be caused by a range of factors including stress, injury, or a reaction to certain foods or medications.
Mouth ulcers usually heal on their own within one to two weeks, but they can be quite uncomfortable in the meantime. In some cases, recurring or large ulcers may require professional attention to rule out underlying conditions.
What Causes Mouth Ulcers?
Mouth ulcers can develop due to a variety of reasons. Understanding the root cause is the first step toward effective management.
1 Physical Injury & Irritation
Accidental biting of the cheek or tongue, sharp foods like chips, dental work, or ill-fitting dentures can physically damage the soft tissue inside the mouth, triggering an ulcer at the injury site.
2 Stress, Hormones & Nutrition
Elevated stress levels, hormonal fluctuations, and nutritional deficiencies (particularly of iron, vitamin B12, and folic acid) are among the most common internal triggers for recurring mouth ulcers.
! Infections & Medical Conditions
Viral or bacterial infections, allergic reactions to certain foods or oral care products, and underlying medical conditions such as autoimmune disorders or gastrointestinal diseases can also cause or worsen mouth ulcers.

Post-Treatment Care for Mouth Ulcers
1 Watch Your Diet
Avoid spicy, acidic, or salty foods that can irritate the ulcer and delay the healing process. Stick to soft, soothing foods like yogurt, soup, and mashed vegetables until healing is complete.
2 Rinse & Keep Clean
Rinse your mouth with warm salt water or an antiseptic mouthwash to keep the ulcer clean and reduce the risk of secondary infection. This also creates a soothing environment for faster tissue repair.
✓ Manage Pain & Lifestyle
Apply a topical oral analgesic gel directly to the ulcer to relieve discomfort. Use a soft-bristled toothbrush and avoid tobacco products, which delay healing. Managing stress through rest and relaxation can also significantly speed up recovery.

Frequently Asked Questions
Common aphthous mouth ulcers (canker sores) are not contagious; you cannot pass them to someone else through contact. However, cold sores caused by the herpes simplex virus are contagious, so it's important to distinguish between the two.
Most minor mouth ulcers heal on their own within 1–2 weeks without any treatment. Major ulcers can take up to 4–6 weeks. If your ulcer persists beyond two weeks or keeps recurring frequently, it's important to see a dentist for evaluation.
You should seek professional advice if the ulcer does not heal within two weeks, if you develop unusually large or painful ulcers, if you experience frequent recurrences, or if the ulcer is accompanied by fever, difficulty swallowing, or other systemic symptoms.
