Canker sores are small lesions that develop inside the mouth and can cause discomfort and pain. They are not contagious and can appear as one or multiple sores.

The exact cause of canker sores is not fully understood, but some experts believe that it could be linked to problems with the immune system, bacteria, viruses, or trauma to the mouth’s soft tissues. These sores are usually white or gray with a red border and can be painful.

Treatment

Although canker sores often heal on their own within one to two weeks, various treatments are available to relieve the pain. Over-the-counter topical anesthetics and antimicrobial mouthwashes can offer temporary relief, and avoiding hot, spicy, or acidic foods can help prevent further irritation. Occasionally, antibiotics from a dentist and oral bandages can help reduce the risk of secondary infection.

Difference Between Canker and Cold Sore

It is important to note that canker sores are not the same as cold sores, which are contagious and develop on the outside of the mouth. The herpes simplex virus is responsible for causing cold sores, which are often accompanied by blisters.

While canker sores are not contagious, they can be painful, and some people may experience frequent outbreaks. In most cases, canker sores do not require medical treatment, but if they persist or become infected, a dentist or doctor can provide further advice and treatment.

If a person experiences frequent or severe outbreaks of canker sores, they should speak to their doctor to determine the underlying cause and seek appropriate treatment. Always maintain good oral hygiene and avoid hot, spicy, or acidic foods to prevent further irritation.
