The American Dental Association (ADA) guidelines provide dentists with the flexibility to make decisions about the frequency of dental x-rays. According to the ADA, those with recurrent tooth decay and other complicated issues should have x-rays taken once or twice a year, while those with optimal dental health may only need them every two to three years. Additionally, full x-rays are often taken prior to certain dental procedures, such as extractions and root smoothing. The frequency of dental x-rays depends on your medical and dental history, as well as the current condition of your mouth.
Some people may need x-rays every six months, while those with excellent oral health may only need them every three years. Panorex x-rays are typically scheduled every 5 to 7 years, depending on your medical and dental history. These x-rays are used to detect impacted teeth, bone abnormalities, cysts, solid growths (tumors), infections, and fractures. The cost of dental x-rays is influenced by the type of x-ray needed, your location, and your dentist's experience.
X-rays are necessary to identify hidden tooth decay in areas between the teeth or under old fillings and crowns. Dr. Gordon Bell uses dental x-rays to get a comprehensive view of his teeth, bones, and gums, as well as to detect small problems before they become major issues. The amount of radiation you receive from dental x-rays is relatively small compared to the radiation you absorb from natural sources in a day.
Provincial regulations require dental offices to follow certain procedures when imaging is taken, such as placing lead aprons and neck collars on patients. Professional dental organizations publish general guidelines on when x-rays should be taken to help dentists make informed decisions.
