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 can be very painful! The exact cause of canker sores is not entirely certain, although several different factors including stress, certain spicy/acidic foods, or vitamin deficiencies can be associated with them. They are also associated with some autoimmune or gastrointestinal conditions such as Crohn's disease or celiac disease. Canker sores typically resolve within a week or so, although aggravating factors such as spicy foods or mechanical trauma can make them take longer to heal. The fact that your canker sores have persisted for over 3 weeks is an indication that you should return for evaluation with either your dentist or your oral surgeon.
