Can Stress Cause Canker Sores?

Canker sores can be a real pain, literally. These sores, which have a white appearance with a red border can occur out of nowhere and be extremely painful. They are not contagious and as of yet, there is no definite reason for their appearance. One common denominator that has been noticed, however, is stress. There is no treatment or prevention for these sores, simply staying away from acidic foods, watching your stress levels and washing your mouth out with an antimicrobial mouthwash can help to ease the pain.
