What are Canker Sores?

Canker sores, also known as aphthous ulcers, are small, open wounds found inside your mouth. They can appear on any of the soft tissues of your mouth including the tongue, roof of your mouth, inside of your cheeks, and even along the gum line. Canker sores can be painful and can make eating, drinking, and talking uncomfortable at times. Fortunately, most canker sores disappear on their own without treatment and are not contagious.

TYPES

There are three general types of canker sores:

CANKER SORE VS. COLD SORE

Though similar in appearance at times, canker sores and cold sores are not the same. Cold sores are fluid-filled blisters caused by the herpes virus and generally appear on the outside of the mouth. Cold sores are also highly contagious, unlike canker sores.

When trying to determine at home whether you have a canker or cold sore, check the location. If it is inside your mouth it is most likely a canker sore, while a sore outside of the mouth is most likely a cold sore.

CAUSES

The precise cause of canker sores remains unknown, though research suggests that a combination of factors may contribute to outbreaks. Some possible causes of canker sores include the following:

Those with underlying health conditions that can result in a weakened immune system, nutritional deficiencies, or gastrointestinal conditions may be at an increased risk of developing canker sores regularly.

SYMPTOMS

Most canker sores are formed in the mouth, are round or oval-shaped, have a white or yellowish center, and typically have a red border. Before they appear you may notice a tingling or burning sensation. They can become inflamed and painful when irritated. In severe cases fever, fatigue, and swollen lymph nodes may also be possible signs of a canker sore.

TREATMENT

Typically, no testing is needed to diagnose canker sores as your dentist or doctor can easily confirm with a quick visual exam. As mentioned above, canker sores typically resolve on their own without treatment. However, please contact your dentist if you notice:

If your canker sore is larger, persistent, or extremely painful, several treatment options exist. Your dentist may prescribe a medicated mouth rinse to reduce pain and inflammation. If your case is severe and does not respond to other forms of treatment, oral prescription medication can be given to relieve symptoms. Cautery through dental lasers can also help to eliminate any source of pain or discomfort.

HOME REMEDIES

Home treatments are beneficial in speeding up the healing process and alleviating symptoms. Common home treatments for canker sores include:

Though there is no cure for canker sores and they can be recurring, there are some ways to reduce your risk. We recommend avoiding foods that may irritate your mouth such as citrus fruits, acidic vegetables, and spicy dishes. Brushing your teeth with a soft-bristled brush after meals and maintaining good flossing habits can help to keep your mouth free of foods that may trigger a sore. Lowering your stress levels by learning better stress management skills may also help to reduce your risk.
