X-Rays

Dental X-rays (also called radiographs) are pictures of the teeth and mouth that show the condition of your teeth, roots, jaw, periodontal status, and overall bone composition. X-rays are useful in the diagnosis of dental diseases, injury, and many abnormal growths (cysts or tumors) and are used to identify the following:

The number, size, and position of teeth
Unerupted or impacted teeth
The presence and extent of dental caries
Bone damage from periodontitis
Abscessed teeth
Fractured jaw
Malocclusion of teeth
Other abnormalities of the teeth and jaw bones

Each type of radiograph is used to see different things, and therefore, may be needed at different intervals. Bitewing x-rays are used to help diagnose cavities (decay) between the teeth and are usually taken every 12 months. Periapical x-rays show the entire tooth, including the root and surrounding bone. These are useful in diagnosing abscesses, impacted teeth or bone loss from periodontal disease and are taken as needed. Panoramic x-rays allow Dr. Hopgood to see a broad view of the entire structure of your jaw in a single image. They are particularly useful for visualizing wisdom teeth, orthodontic needs, dental implant treatment planning, and diagnosing pathology. Panoramic x-rays are taken once every three to five years (depending on the age of the patient and dental procedure). All new patients are required to take a Full Mouth series (also called an FMX) which is taken every three to five years based on periodontal need. An average FMX is 18-22 films depending on the number of teeth in the mouth and is made up four bitewing x-rays and approximately 18 periapical films. It is used to see a combination of bone levels, apical pathology, as well as interproximal decay. It is a comprehensive view of the mouth essential for new patients. Like other aspects of your dental care, dental X-rays are scheduled on an individual basis and may vary with your age, risk for disease, and signs of disease.

X-Rays & Radiation

We only take radiographs when necessary to limit your exposure to radiation, and all patients wear a lead apron to avoid unnecessary radiation to other parts of the body. Not all patients need x-rays at the same intervals, and some need to have x-rays taken more frequently to address suspected problems in their teeth, jaw, and gums. Seeing how children's mouths grow and change rapidly, they tend to need radiographs more often than adults. The American Academy of Pediatric Dentistry recommends x-rays every six months for children with a history or high risk of tooth decay while children with no history require x-rays less frequently and on the advice of their dentist.

With new technology and the advancement of digital x-rays, the amount of radiation received from dental machines is insignificant. The benefits from dental radiographs far outway the hazards. Without dental x-rays we could miss finding decay, periodontal disease, cysts, or tumors.
