Cold sores are a cluster of blisters that first appear clear then become cloudy. First infection may be inside the mouth, but cold sores generally appear outside the mouth on the lips. Canker sores are gray or white sores surrounded by a red inflamed area.old sores typically result from a viral infection called herpes simplex virus (HSV). Cold sore blisters can occur on many different parts of the body but are most common on or around the lips, cheeks, or nose and also (on rare occasions) in the eye.
Canker sores are not a form of herpes, however, they are often confused and mistaken as herpes. Canker sores are not considered to be contagious. Cold sores and mouth herpes on the other hand are caused by the herpes simplex virus and can be very contagious. Canker sores usually occur inside the mouth, are gray in color and have a distinct edge. The sores will usually heal within 10 to 14 days, without treatment.
