Canker and 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.
