Dental X-rays

Dental X-rays may reveal:

• Abscesses or cysts.
• Bone loss.
• Cancerous and noncancerous tumors.
• Decay between the teeth.
• Developmental abnormalities.
• Poor tooth and root positions.
• Problems inside a tooth or below the gumline.

Detecting and treating dental problems at an early stage can save you time, money, unnecessary discomfort, and your 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 digital equipment that minimizes exposure time.

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, current symptoms, and risk factors.

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 (checkup) visits and are recommended once or twice a year to detect new dental problems.
