You may wake up one morning and without any warning, you see a small sore along the inside of your mouth or lip. Most likely this is a common canker sore, is not contagious, and typically resolves on its own or by administering simple home remedies. However, it can provide some discomfort and can get irritated further by foods you eat. Anyone can develop a canker sore, and in fact, they affect 20% of the population at one time or another. They tend to be more common in people ages 10-20 and are more prevalent in Caucasians.
