Digital radiography (digital x-ray) is the latest
technology used to take
dental x-rays. This technique uses an electronic sensor
(instead of x-ray film) that
captures and stores the digital image on a computer.
This image can be instantly viewed
and enlarged helping the dentist and dental hygienist
detect problems easier. Digital
x-rays reduce radiation 80-90% compared to the already
low exposure of traditional dental
x-rays.
Dental 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 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
may save you time, money, unnecessary discomfort, and your teeth!
Are dental x-rays safe?
We are all exposed to natural radiation in our
environment. Digital x-rays produce a significantly lower level of radiation compared to
traditional dental x-rays. Not only are digital x-rays better for the health and safety of the
patient, they are faster and more comfortable to take, which reduces your time in the
dental office. Also, since the digital image is captured electronically, there is no need to
develop the x-rays, thus eliminating the disposal of harmful waste and chemicals into the
environment.
Even though digital x-rays produce a low level of
radiation and are considered very safe, dentists still take necessary precautions to limit the
patient’s exposure to radiation. These precautions include only taking those x-rays that
are necessary, and 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 upon the review of your medical and dental history, a dental
exam, signs and symptoms, your age, and risk of 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.
