Dental Examinations

Teeth are an important part of any holiday celebration. After all, it's difficult to enjoy a meal without them. So let's talk about dental health.

Dentists say people should have their mouth examined every six months to make sure their teeth are healthy. But dentists look for more than holes in teeth and problems with the gums (десны). Examinations are also important because they can show medical problems in other parts of the body.

For example, a dentist can see in a patient's mouth the beginning of diseases such as measles (корь) or mumps (свинка). The doctor can also diagnose diabetes. And a person whose gums are too red may not get enough vitamin D. It may cause a disease called rickets (рахит).

Experts say early signs of more than forty health problems can be seen in a person's mouth or on the tongue. These include the deadly disease AIDS and a lack of many different vitamins. When dentists recognize possible signs of a disease, they send the patients for medical tests, or to a doctor for treatment.

Some dentists organize programs to help people to stop smoking. Smoking cigarettes can cause mouth, lung and throat cancer.

Finally, as any dentist will tell you, teeth need daily care. This means not only brushing them, but also using dental floss (зубная нить) to prevent gum infections.
