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 X-rays, problem areas may go undetected.

Dental X-rays may 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 early can save you time, money, unnecessary discomfort, and teeth!

​

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.
