What are Canker Sores?
A canker sore, also known as an aphthous ulcer, looks like a small, round or oval lesion that has a white or yellowish center surrounded by red. They tend to be indented, like a crater, rather than raised, like a bump.
It’s easy to confuse cold sores and canker sores. Unlike a cold sore, a canker sore is not contagious, and it appears on the inside tissues of the mouth rather than the outer surface of the lip (which is where cold sores appear).
Causes of Canker Sores
The exact cause of canker sores remains uncertain, but possible factors include an allergic reaction to bacteria in the mouth, a minor injury to the inside of the mouth due to dental work or poorly fitting dental appliances, food allergies or health problems, such as celiac disease and inflammatory bowel diseases.

What Do Canker Sores Look Like?
Canker sores most often appear on the inside of the cheeks and lips or at the base of the gum. Canker sores are not usually associated with bleeding gums, so if you are experiencing bleeding gums you should see your dental professional to be evaluated for possible gum disease. The majority of canker sores are mild. Mild canker sores are less than one-third of an inch long and usually heal on their own after a few weeks.
But major aphthous ulcers, defined as larger than 10mm in size, can take more than a month to heal and can cause scarring when they finally do heal. So, it’s important to visit your doctor or dental professional if you have a canker sore that has persisted for more than a few weeks. These large ulcers are most common in young adults after puberty, and they are more likely to recur than smaller sores. Older adults are more prone to lesions, in which dozens of tiny lesions group together to form a large ulcer.
Canker Sores Treatments
Although most canker sores resolve on their own, if you have a large or stubborn lesion, your dental professional may prescribe an antibiotic mouth rinse, topical paste to apply to the lesion, or a nutritional supplement if poor nutrition may be the cause of the canker sore.
Keep Up with a Good Oral Care Routine
Whether or not you suffer from canker sores, it’s important to maintain a thorough oral care regiment to ensure your teeth and gums stay healthy:
- Brush teeth at least twice a day with the Oral-B iO Series 9 Rechargeable Toothbrush . Its dentist-inspired round brush head expertly cleans with micro-vibrations to remove more plaque than a manual brush.
- Pair the Oral-B iO with a toothpaste containing Stannous Fluoride like Crest Gum Detoxify, its activated foam formula removes plaque bacteria in hard-to-reach areas to better reverse gingivitis.
- Floss at least once a day to remove more plaque and debris from tight spaces. The Oral-B Pro-Health Advanced Floss slides up to 50% more easily in tight spaces than other types of floss. To further improve your gum health, supplement your regular flossing routine with the Oral-B Water Flosser Advanced, its unique Oxyjet Technology helps eliminate more plaque bacteria* for healthier gums.
- Swish with an alcohol-free mouthwash that’s designed to cleanse sores and minor wounds like the Oral-B Mouth Sore Special Care Oral Rinse . It’s scientifically formulated for a gentle yet effective clean for canker sores, cheek bites, braces, and denture irritations.
*Helps reduce plaque bacteria and inflammatory components associated with gingivitis, when used as an adjunct to brushing, flossing and regular professional care.
