Cold Sores and Canker Sores

Mouth sores such as cold and canker sores that develop in and around the mouth can cause significant discomfort. They can be caused by orthodontic wire scraping against the mouth, a broken or sharp tooth, biting the inside of the mouth, and infections caused by fungus, bacteria or virus. 

Mouth sores can also be a symptom of a systemic disorder or disease, so if the pain is severe or sores last longer than two weeks, contact Dr. Walters. 

Canker Sores

Canker sores are one or several small white or gray lesions with a red border that develop inside the mouth. They are not contagious and usually heal on their own after one or two weeks. Avoid hot, spicy, or acidic foods to prevent the sores from becoming more irritated. 


Cold Sores

Cold sores, or fever blisters, are fluid-filled blisters that form in groups around the lips, nose or chin. They are caused by the herpes simplex virus and are very contagious. Once a person is infected, the virus remains in their body and causes occasional cold sore outbreaks. Cold sores will generally heal by themselves within a week. 

If you are in extreme discomfort or if the canker or cold sore lasts longer than two weeks, call Dr. Walters for treatment options: 614-662-2082.
