Due to the ability of radiographs (X-Rays) to show cavities between teeth and deep beneath the pits in teeth, they are used routinely in dental care. Without x-rays, dentists can’t always spot decay. The decay is often hidden by the tooth’s shape. In fact, x-rays can detect more than cavities. Dentists also use dental radiographs to check for incorrectly erupting teeth, tumors in the skull or jaw, to examine the health of the jaw bones, to detect fractures of teeth or jaws and for planning orthodontic treatment. They can allow dentists to survey erupting teeth, examine teeth injuries, diagnose bone diseases and treat other health problems. If problems are found soon enough, the treatment and care is more affordable and more comfortable. The American Academy of Pediatric Dentistry recommends a child gets x-rays and cleanings every six months, especially if they have a high risk for tooth decay. Most pediatric dentists only x-ray once a year. A complete set of x-rays are recommended at least every three years (including panoramic and bitewings or periapicals and bitewings). Most pediatric dentists are very careful to minimize the exposure to radiation when your child is x-rayed. The amount of radiation exposure is very small with common safeguards used in the dental office. In fact, the risks associated with x-rays are minute compared to risks associated with untreated dental problems. Lead aprons and shields will help protect patients being x-rayed and new equipment helps filter out unneeded x-rays. Thus, the system is effective and efficient.
