Tooth decay and periodontal disease are the most common causes of tooth loss. Tooth decay takes place when most of the tooth’s mineral makeup has been dissolved away and a hole (cavity) has formed. While tooth decay primarily affects children, periodontal disease, or gum disease, affects mostly adults. Periodontal disease is an infection of the gums caused by the buildup of plaque, and its earliest stage is known as gingivitis.

Most dental professionals recommend that you brush your teeth at least twice a day. Brushing after every meal (and flossing at least once a day) is also a good way to maintain dental health.

A child should have his first dental appointment no later than his third birthday. Many dentists recommend a child have his first appointment when his first tooth comes in.

Tobacco (cigarettes, pipes, cigars, chewing tobacco, and snuff) is the most common cause of oral cancer. Combining tobacco use with heavy drinking can also foster the development of oral cancer. Bad hygiene, prolonged irritation of the oral cavity, and extended exposure to strong sunlight on the lips are among other causes of the disease. Many dentists believe vitamins A and E can help prevent the acquisition of oral cancer.

Early symptoms of oral cancer include: a sore on the lip, in the mouth, or in the throat that does not heal; a lump on the lip, in the mouth, or in the throat; a red or white patch found anywhere in the mouth; unusual pain or bleeding in the mouth; swelling of the mouth; and any difficulty or discomfort felt in chewing or swallowing.
