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.

BULIMIA NERVOSA

People with eating disorders can suffer from oral health problems as well. This is because many of the behaviors associated with anorexia nervosa and bulimia nervosa such as binge eating, self-induced vomiting, and use of diuretics or laxatives cause changes in the mouth.

For example, repeated episodes of vomiting, which is common in people with bulimia, release harmful stomach acids that pass through the mouth and can erode tooth enamel, causing cavities, discoloration and tooth loss.  Other problems, such as poorly fitting fillings and braces, are another byproduct of such eating disorders.

Brushing after episodic vomiting is actually more harmful than one would think. The best practice is to rinse thoroughly with a neutral solution such as baking soda and water.
