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. |
