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.
