Canker Sores and Common Mouth Sores

Mouth sores occur for many different reasons. Often they are because of infection or bacteria in the mouth. Canker sores are among some of the most common mouth sores. It’s a common misconception that canker sores are contagious. While it’s not completely clear what causes them it’s believed by some professionals that they are caused by an immune system reaction or by bacteria in the mouth. They’re often white or gray with bright red surrounding them, and very painful and can unfortunately return. The only treatment for canker sores is over-the-counter topical anesthetics.

Cold sores are another common type of mouth sore that is caused by the herpes virus. They’re incredibly contagious and very painful. These small blisters manifest in a single area outside the mouth and not because of the common misconception that these cold sores are caused by a cold or the flu. They are a flare of the herpes virus and an immune reaction to it that could be triggered by another illness or virus attacking your body at the same time. There is no cure for permanently getting rid of a cold sore. Once you have them you can always get them. Treatment includes antivirals or over-the-counter topical treatments.

Candidiasis, also known as thrush mouth, is caused by a fungal infection in the mouth and is common among those with diabetes, dentures or even those who use asthma medications. Good oral hygiene is the only way to prevent candidiasis. Often these sores manifest all over the mouth and need to be diagnosed by a professional to truly be able to treat them.
