Mouth ulcers, sometimes called canker sores, are small but painful spots that can develop inside the mouth. While many ulcers heal on their own, frequent or severe sores may indicate an underlying issue that needs attention.
What causes mouth ulcers?
Common causes include minor injuries from biting the cheek, irritation from dental appliances, stress, hormonal changes, or sensitivity to certain foods. In some cases, nutritional deficiencies or immune-related conditions may play a role.
Are mouth ulcers contagious?
No. Unlike cold sores, mouth ulcers are not caused by a virus and cannot be passed from person to person.
How long do mouth ulcers usually last?
Most mouth ulcers heal within one to two weeks without treatment. During this time, discomfort can often be managed by avoiding spicy or acidic foods and keeping the area clean.
When should you see a dentist?
If mouth ulcers last longer than two weeks, keep returning, or are extremely painful, a dental exam can help determine the cause. Persistent sores may require further evaluation to rule out more serious conditions.
