Are dental x-rays safe?
We are all exposed to natural radiation in our environment. The amount of radiation exposure from a full mouth series of x-rays is equal to the amount a person receives in a single day from natural sources.
Dental x-rays 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 x-rays. These precautions include using lead apron shields to protect the body and using modern, fast film that cuts down the exposure time of each x-ray.
How often should dental x-rays be taken?
The need for dental x-rays depends on each patient’s individual dental health needs. Your dentist and dental hygienist will recommend necessary x-rays 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 x-rays is recommended for new patients. A full series is usually good for three to five years. Bite-wing x-rays (x-rays of top and bottom teeth biting together) are taken at recall (check-up) visits and are recommended once or twice a year to detect new dental problems.
