X-Rays
|
|
When X-rays pass through your mouth during a dental exam, more X-rays
are absorbed by the denser parts (such as teeth and bone) than by soft
tissues (such as cheeks and gums) before striking the film. This creates
an image on the radiograph. Teeth appear lighter because fewer X-rays
penetrate to reach the film. Cavities and gum disease appear darker
because of more X-ray penetration. The interpretation of these X-rays
allows the dentist to safely and accurately detect hidden abnormalities.
How often dental X-rays (radiographs) should be taken depends on the
patient`s individual health needs. It is important to recognize that
just as each patient is different from the next, so should the
scheduling of X-ray exams be individualized for each patient. Your
medical and dental history will be reviewed and your mouth examined
before a decision is made to take X-rays of your teeth.
The schedule for needing radiographs at recall visits varies according
to your age, risk for disease and signs and symptoms. Recent films may
be needed to detect new cavities, or to determine the status of gum
disease or for evaluation of growth and development. Children may need
X-rays more often than adults. This is because their teeth and jaws are
still developing and because their teeth are more likely to be affected
by tooth decay than those of adults. |
