Let’s delve into a topic that might not top the list of dinner table discussions: mouth sores. While not the most pleasant subject, they are quite common. Familiarizing yourself with their potential causes can help you identify what’s happening when a sore appears in your mouth.

Mouth sores can manifest anywhere in or around the mouth, including the gums, inner cheeks, tongue, lips, or roof of the mouth.

Regular check-ups with your health professional are essential, especially if you suspect a chronic or acute oral issue.

There are various types of mouth sores. Different mouth sores come with different symptoms and potential risks; some are simply bothersome, while others may necessitate professional treatment.

The development of mouth sores isn’t attributed to one singular cause, and susceptibility may vary from person to person. With that in mind, here’s a brief overview of some of the most prevalent factors leading to mouth sores:

Certain Medical Conditions: Some conditions affecting the intestines, like Crohn’s disease, food sensitivities, and ulcerative colitis, may increase the likelihood of developing mouth sores. This correlation aligns with the growing body of research linking oral health to gut health. Mouth sores may also be a result of allergies, autoimmune disorders, bleeding disorders, a weakened immune system, or, in rarer cases, oral cancer. Cold sores, on the other hand, are caused by the herpes simplex virus.

Certain Foods or Beverages: Consuming acidic, salty, and/or spicy foods or drinks can lead to irritation in the mouth, which in turn, may result in mouth sores. (More on this below.)

Chewing Tobacco: Using chewing tobacco is strongly associated with an increased susceptibility to mouth sores. Another compelling reason to kick the habit!

Hormonal Changes: Natural hormonal fluctuations occur in individuals of all genders throughout each month, potentially heightening the likelihood of developing mouth sores. The same applies to hormonal shifts during pregnancy.

Infection: Many mouth sores are a consequence of bacterial, fungal, or viral infections. In these instances, the infection triggers inflammation and an immune system response, often leading to swelling at the site of the sore.

Irritation: Persistent irritation in a specific area of the mouth (perhaps due to sharp braces, an ill-fitting denture, a rough edge from a filling, consuming certain types of foods, or accidental cheek or tongue biting) can give rise to the formation of a mouth sore.

Nutritional Deficiencies: A diet lacking essential vitamins and minerals can heighten the chances of developing mouth sores. Vitamin B12 and folate deficiencies are two common culprits.

Stress: While it may seem unexpected, stress induces inflammation throughout the body. When inflammation is present, it increases the likelihood that minor infections or irritations may develop into sores.

In many instances, mouth sores will resolve on their own within a couple of weeks. However, if a mouth sore persists, is associated with an infection, or is accompanied by symptoms like fever or difficulty swallowing, it’s time to seek advice from a dentist.
