What Is Canker Sore?
Canker sores (aphthous ulcers) are a common oral condition marked by shallow, painful ulcers that form on the soft tissues inside the mouth, including the inner cheeks, lips, tongue, and gums. They can cause significant discomfort during eating, speaking, and swallowing. With the right treatment and support, most canker sores heal within one to two weeks and recurrences can often be reduced.

Frequently asked questions
The exact cause of canker sores is not fully understood, but common triggers include minor mouth injuries, stress, hormonal changes, certain foods, and nutritional deficiencies such as low vitamin B12, folate, or iron. Some people have a genetic predisposition to recurrent aphthous ulcers.
Minor canker sores, which are the most common type, usually heal on their own within 7 to 14 days. Major aphthous ulcers can take several weeks to heal and may leave scarring. Treatment can help relieve pain and may speed the healing process.
No. Canker sores are not contagious and cannot be spread through saliva, kissing, or sharing utensils. They are distinct from cold sores, which are caused by the herpes simplex virus and are contagious.
You should seek medical evaluation if a sore is unusually large (greater than 1 cm), lasts more than two weeks, is extremely painful, recurs frequently, or is accompanied by fever, swollen lymph nodes, or difficulty swallowing. These may indicate a need for prescription treatment or further workup.
Over-the-counter options such as topical anesthetics, antiseptic mouthwashes, and protective oral gels can help relieve pain and protect the ulcer. Avoiding spicy, acidic, or rough-textured foods can also reduce irritation during healing.
Yes. Deficiencies in vitamin B12, folate, zinc, and iron have been linked to an increased frequency of canker sores. A physician can assess whether supplementation or dietary changes may help reduce recurrences.
