Tooth Decay

Tooth decay is the disease known as caries. Unlike other diseases, however, caries is not life threatening and is highly preventable, though it affects most people to some degree during their lifetime.

Tooth decay occurs when your teeth are frequently exposed to foods containing carbohydrates (starches and sugars) like soda pop, candy, ice cream, milk, cakes, and even fruits, vegetables and juices. Natural bacteria live in your mouth and form plaque. The plaque interacts with deposits left on your teeth from sugary and starchy foods to produce acids. These acids damage tooth enamel over time by dissolving, or demineralizing, the mineral structure of teeth, producing tooth decay and weakening the teeth.

Sensitive Teeth

Tooth sensitivity is caused by the stimulation of cells within tiny tubes located in the dentin (the layer of tissue found beneath the hard enamel that contains the inner pulp). When the hard enamel is worn down or gums have receded-causing the tiny tube surfaces to be exposed-pain can be caused by eating or drinking food and beverages that are hot or cold; touching your teeth; or exposing them to cold air.

Hot and cold temperature changes cause your teeth to expand and contract. Over time, your teeth can develop microscopic cracks that allow these sensations to seep through to the nerves. Exposed areas of the tooth can cause pain and even affect or change your eating, drinking and breathing habits. Taking a spoonful of ice cream, for example, can be a painful experience for people with sensitive teeth.

Gum Disease

Gum disease (also called periodontal disease) is an infection of the tissues surrounding and supporting the teeth. It is a major cause of tooth loss in adults. Because gum disease is usually painless, however, you may not know you have it.

Gum disease is caused by plaque, a sticky film of bacteria that constantly forms on the teeth. These bacteria create toxins that can damage the gums.

In the early stage of gum disease, called gingivitis, the gums can become red, swollen and bleed easily. At this stage, the disease is still reversible and can usually be eliminated by daily brushing and flossing.

In the more advanced stages of gum disease, called periodontitis, the gums and bone that support the teeth can become seriously damaged. The teeth can become loose, fall out or have to be removed by a dentist.

Bad Breath

What you eat affects the air you exhale. Certain foods, such as garlic and onions, contribute to objectionable breath odor. Once the food is absorbed into the bloodstream, it is transferred to the lungs, where it is expelled. Brushing, flossing and mouthwash will only mask the odor temporarily. Odors continue until the body eliminates the food. Dieters may develop unpleasant breath from infrequent eating.

If you don't brush and floss daily, particles of food remain in the mouth, collecting bacteria, which can cause bad breath. Food that collects between the teeth, on the tongue and around the gums can rot, leaving an unpleasant odor. Dentures that are not cleaned properly can also harbor odor-causing bacteria and food particles.

One of the warning signs of periodontal (gum) disease is persistent bad breath or a bad taste in the mouth. Periodontal disease is caused by plaque, the sticky, colorless film of bacteria that constantly forms on teeth. The bacteria create toxins that irritate the gums. In the advanced stage of the disease, the gums, bone and other structures that support the teeth become damaged. With regular dental checkups, your dentist can detect and treat periodontal disease early.

Canker Sores

Canker sores occur inside the mouth. A canker sore (also called aphthous ulcers) is a small ulcer with a white or gray base and red border. There can be one or a number of sores in the mouth. Canker sores are very common and often recur.

Canker sores usually heal in about a week or two. Rinsing with anitmircobial mouthrinses may help reduce the irritation. Over-the-counter topical anesthetics can also provide relief.

Orthodontic Problems

An orthodontic problem is called a malocclusion, meaning "bad bite." Some examples of causes of malocclusion are crowded teeth, extra teeth, missing teeth or jaws that are out of alignment.

Most malocclusions are inherited, although some can be acquired. Acquired malocclusions can be caused by accidents, early or late loss of baby teeth, or sucking of the thumb or fingers for a prolonged period of time.
