The Story on Canker Sores

Canker sores are quite literally stomatitis. Why do they appear, and what can be done about them? Anyone who’s ever had mouth sores can attest to the fact that they are painful, but simply suffering through them does you no good.

Because they are similar in name and can appear within fairly close proximity of each other, canker sores are often confused with cold sores. An easy way to tell the difference right off the bat is by checking to see if it’s on the inside or outside of your mouth. Cold sores, which are viral and highly contagious in nature, will appear outside of the mouth, on or close to the lip area. Canker sores, on the other hand, are not contagious and emerge along the insides of your cheeks, gums and the roof of your mouth. If you spot an inflammation with a white center and red border inside your mouth, and it causes sensitivity or soreness when talking or eating, it’s most likely a canker sore.

Considering that stomatitis is often chronic, those who experience canker sores due to an injury, or eating something overly acidic, might actually consider themselves lucky. Otherwise, recurring flare-ups can be expected, especially if your case is connected to underlying conditions such as:  stress, menstruation, HIV and other blood disorders, food allergies, Crohn’s disease, Lupus, genetics, immune disorders, fatigue, orthodontic treatment, vitamin deficiencies, and chemotherapy.  It is also worth noting that canker sores tend to be more common in teens, young adults and women.

On average, canker sores usually last between 7 and 10 days. While there is no way to rid yourself of a canker sore once it emerges, there are plenty of things you can do to alleviate the discomfort until it heals, such as: 1. try an over-the-counter gel or painkiller for immediate relief. 2. steer clear of spicy, acidic and/or hot foods to avoid aggravating open sores. 3. rinse with water or mouthwash regularly to keep the sores free of food particles.  4. brush and floss with extra care to prevent unnecessary contact and/or added trauma.

Understanding what caused the outbreak can also help you take preventative measures to minimize the chance of future flare-ups. If sores are food or allergy related, for example, simply steering clear of triggers can keep stomatitis at bay.
