Dental X-Rays
Why have Dental X-Rays?
Dental radiographs (x-rays) are essential, diagnostic tools that provide information not visible during a dental exam. Dentists and dental hygienists use this information to accurately detect hidden problems and complete an accurate treatment plan. Without x-rays, problem areas may go undetected.
What they can Reveal
- Abscesses or cysts
- Bone loss
- Cancerous and non-cancerous tumours
- Decay between the teeth
- 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 x-rays safe?
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.
Dentists take precautions to limit the exposure to radiation when taking dental x-rays. These include using a lead apron and using, fast film that cuts down the exposure time of each x-ray.
How often should dental x-rays be taken?
The need for 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.
