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.

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. 

Fluorosis is a condition in which your body has been exposed to too much fluoride. In normal doses (typically found in a safe drinking water system and an ADA-approved toothpaste), fluoride is a healthy compound that promotes strong teeth, which has the ability to fight cavities and other problems.

Saliva is one of your body's natural defenses against plaque because it acts to rinse your mouth of cavity-causing bacteria and other harmful materials. Dry mouth (also called Xerostomia) is a fairly common condition that is caused by diminished saliva production.

People living with diabetes are vulnerable to a host of systemic problems in their entire body. Unfortunately, the mouth and teeth are not immune from such problems, and many diabetics with oral problems go undiagnosed until conditions become advanced.

Oral cancer is one of the most common cancers today and has one of the lowest survival rates, with thousands of new cases being reported each year. Fewer than half of all people diagnosed with oral cancer are ever cured. Moreover, people with many forms of cancer can develop complications.

Any kind of cut to your face and the delicate soft tissues inside your mouth should be addressed immediately in order to prevent further tissue damage and infection.

If a traumatic injury involves a broken facial bone such as the jaw, nose, chin or cheek, maxillofacial surgery may be required.

People who grind their teeth can sometimes develop a serious problem with their jaw, which left untreated, can adversely affect the teeth, gums and bone structures of the mouth. One of the most common jaw disorders is related to a problem with the temporomandibular joint, the joint that connects your lower jaw to your skull, and allows your upper and lower jaw to open and close and facilitates chewing and speaking.

Gingivitis is the medical term for early gum disease, or periodontal disease. In general, gum disease can be caused by long-term exposure to plaque, the sticky but colorless film on teeth that forms after eating or sleeping. Gum disease originates in the gums, where infections form from harmful bacteria.

Teeth grinding, also called bruxism, is often viewed as a harmless, though annoying, habit. Some people develop bruxism from an inability to deal with stress or anxiety. However, teeth grinding can literally transform your bite relationship and worse, severely damage your teeth and jaws over long periods of time.

If you wince with pain after sipping a hot cup of coffee or chewing a piece of ice, chances are that you suffer from "dentin hypersensitivity," or more commonly, sensitive teeth. Hot and cold temperature changes cause your teeth to expand and contract.

Plaque is a film of bacteria that forms on your teeth and gums after eating foods that produce acids. These foods may include carbohydrates (starches and sugars), such as candy and cookies, and starchy foods such as bread, crackers, and cereal. Tooth decay, commonly known as cavities, occurs when plaque remains on your teeth for an extended period of time, allowing the bacteria to ‘eat away’ at the surfaces of your teeth and gums.

An abscessed tooth is a pocket of pus, usually caused by some kind of infection and the spread of bacteria from the root of the tooth to the tissue just below or near the tooth. In general, a tooth that has become abscessed is one whose underlying pulp (the tooth's soft core) has become infected or swollen.
