Dental radiographs (x-rays) are essential, preventative, diagnostic tools that provide valuable information not visible during a regular dental exam. Dentists and dental hygienists use this information to safely and accurately detect hidden dental abnormalities and complete an accurate treatment plan. Without radiographs, problem areas may go undetected because they are not visible with the naked eye.
Dental radiographs may reveal:
-
Abscesses or cysts.
-
Bone loss.
-
Cancerous and non-cancerous tumors.
-
Decay between the teeth and under existing restorations.
-
Developmental abnormalities.
-
Poor tooth and root positions.
-
Problems inside a tooth or below the gum line.
Detecting and treating dental problems at an early stage can save you time, money, unnecessary discomfort, and your teeth!
Are dental radiographs safe?
We are all exposed to natural radiation in our environment. The amount of radiation exposure from a full mouth series of radiographs is equal to the amount a person receives in a single day from natural sources.
Dental radiographs produce a low level of radiation and are considered safe. Dentists take necessary precautions to limit the patient’s exposure to radiation when taking dental radiographs. These precautions include using lead apron shields to protect the body and using modern, fast film or digital radiography that cuts down the exposure time of each radiograph.
How often should dental radiographs be taken?
The need for dental radiographs depends on each patient’s individual dental health needs. Your dentist and dental hygienist will recommend necessary radiographs based on the review of your medical and dental history, dental exam, signs and symptoms, age consideration, and risk for disease.
A full mouth series of dental radiographs is recommended for new patients. A full series is usually good for three to five years. Bite-wing radiographs (radiographs of top and bottom back teeth biting together) are taken at recare (check-up) visits and are recommended once or twice a year to detect new dental problems.
