Dental amalgam, or silver filling material, is a mixture of mercury,
and an alloy of silver, tin and copper. The release of mercury in
silver fillings is so small that it is much less than what patients
are exposed to in food, air and water. There are, however, other
materials that can be used for restorations. These include gold,
porcelain, and composite resins.
Fluoride is a compound of the element fluorine, which is found
universally throughout nature in water, soil, air and in most foods.
Fluoride is absorbed easily into the tooth enamel, especially in
children's growing teeth. Once teeth are developed, fluoride makes the
entire tooth structure more resistant to decay and promotes
remineralization, which aids in repairing early decay before the
damage is visible.
Radiographs, or x-rays, help your dentist determine the presence or
degree of periodontal disease, abscesses, and many abnormal growths
such as cysts and tumors. They can help pinpoint the location of
cavities and other signs of disease that may not be possible to detect
through a visual examination. All health care providers are sensitive
to patients' concerns about exposure to radiation. Your dentist has
been trained to prescribe radiographs when they are appropriate and to
tailor the radiograph schedule to your individual needs. By using
state-of-the-art technology, such as digital radiography, and by
staying knowledgeable about recent advances, your dentist knows which
techniques, procedures and X-ray films can minimize your exposure to
radiation.
