Do you ever get sores in your mouth that seem to appear for no reason and then disappear just as mysteriously? Chances are they’re aphthous ulcers — better known as canker sores.
These are irritating breaks in the protective lining of the mouth (oral mucosa) — akin to a blister without its dome — that are yellowish/grayish in the center surrounded by an aggravated red border. They typically develop in movable, thinner oral membranes such as the cheeks and lips, under the tongue, or the soft palate at the back of the mouth. Because they expose underlying tissues, canker sores can be quite painful, especially when eating or drinking.
Recurrent aphthous ulcers (RAS) affect up to 25% of the population, making them one the most common oral conditions. They are considered “minor” when they are smaller and “major” when they exceed 1 centimeter in diameter. Larger ones take more time to heal and may cause scarring. A less common type is herpetiform aphthae, so named because the small clusters of ulcers that characterize it are similar in appearance to those caused by the herpes simplex virus (HSV1). However, unlike herpes-related cold sores and fever blisters, canker sores in any form are not contagious. Another difference is that ulcers from the herpes virus occur more frequently on the gums and hard palate.
No Clear Cause
There is no clear cause for canker sores. They often appear during stressful periods and times when resistance is down, suggesting an immune system malfunction. They may also be an allergic reaction to ingredients in food or oral products like toothpaste or mouthwash or related to an underlying medical conditions such as gastrointestinal diseases or nutritional deficiencies.
Canker sores usually resolve on their own within seven to ten days. Various over-the-counter and prescription treatments can help facilitate healing and help minimize pain along the way. If they do not resolve within two weeks; or they increase in severity, frequency or duration; or you’re never without a mouth sore it’s important to seek dental or medical attention as they could signify a more serious condition.

Sometimes it's the little things that can be most annoying. Those occasional small sores that pop up on the inside of your mouth are a case in point. Although in most instances they won't last long and aren't anything to be alarmed about, they can still cause you some discomfort.
These small sores are called aphthous ulcers or more commonly “canker sores.” They are breaks in the skin or mucosa, the inner lining of the mouth, and occur most often on the inside cheeks, lips, tongue and occasionally on the soft palate at the back of the throat. They usually appear round with a yellow-gray center and an intensely red outer ring or "halo."
Canker sores often appear during periods of high stress or because of minor trauma, and usually last for a week or two. They often have a tingling pain that can be aggravated when you eat and drink acidic or spicy foods and beverages. About 20 to 25% of people have a form known as recurrent aphthous stomatitis (mouth inflammation) that occurs regularly with multiple sores and heightened pain.
It's possible to manage the discomfort of minor, occasional bouts with a number of over-the-counter products that cover the sore to protect it and boost healing, with some providing a numbing agent for temporary pain relief. For more serious outbreaks we can also prescribe topical steroids in gels or rinses, injections or other medications.
While canker sores don't represent a health danger, there are instances where you should take outbreaks more seriously: if a sore hasn't healed after two weeks; if you've noticed an increase in pain, frequency or duration of outbreaks; or if you're never without a sore. In these cases we may need to biopsy some of the tissue (and possibly run some blood tests) to ensure they're not pre-cancerous or cancerous.
In any event, we can work with you to reduce your symptoms and help the sores heal quickly. This particular “little thing” in life doesn't have to stress you out.
