Your third set of molars are no different than any other tooth, save for the fact that they are the last to erupt, or grow, into the mouth. Because they typically do so at around the age of 18 to 20, when adolescents are close to turning into adults, these teeth are commonly referred to as "wisdom teeth."
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.
