Canker/Cold Sores
People sometimes confuse canker sores and cold sores, but they are
completely unrelated. Both can be painful, but knowing the differences
can help you keep them in check.
A canker sore is typically one that occurs on the delicate
tissues inside your mouth. It is usually light-colored at its base and
can have a red exterior border.
A cold sore or fever blister, on the other hand, usually
occurs on the outside of the mouth, usually on or near the nose or
lips. A cold sore is contagious because it is caused by the herpes
simplex virus, and it is usually painful and filled with fluid.
In most cases, patience is the best medicine for treating
canker sores. A healthy diet and good oral hygiene are usually the best
remedy, but some special rinses and anesthetics can help. Cold sores
can be treated effectively with some over-the-counter topical creams;
sometimes, an antiviral medication will be prescribed by your doctor.
