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.

Digital radiography is one of the most important new advances that our profession has seen in quite some time. The capability to reduce the exposure of radiation to the patient while increasing our diagnostic proficiency has astounding implications. The reduction of the use of harsh chemicals and other waste materials associated with traditional radiography is also an added benefit to our environment. 

Dental X-rays may reveal:

• Abscesses or cysts.
• Bone loss.
• Cancerous and non-cancerous tumors.
• 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?

Digital radiography systems reduce radiation exposure to patients by up to 80 percent compared to film-based systems. Although there is no question that contemporary, film-based radiography systems are indeed exceptionally safe, digital radiography conforms to the very important ALARA principle: As Low As Reasonably Achievable. 

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.

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.
