X-rays, also called radiography, provide an important tool that shows the condition of your teeth, roots, jaw, and overall facial bone composition. X-rays can reveal the advanced nature of periodontal disease, as well as tumors and abscesses.
There are three basic kinds of X-rays:
- Bite wings are the most conventional kind of dental X-rays and are used to spot cavities and decay.
- Peri-apical X-rays are broad pictures of an entire tooth structure and are used to spot deep tooth problems, such as impacted teeth, bone loss, and abscesses.
- Panoramic X-rays are designed to capture an entire mouth, and have been used to spot tumors and cysts, as well as wisdom teeth.
Radiation Concerns
Patients have little reason to be concerned about the health effects of dental X-rays; chances are you receive more radiation from sunlight in one day than one sitting involving dental X-rays.
Exposure to radiation is extremely brief and minimal. Safety precautions such as highly sensitive digital sensors minimize exposure time, and lead aprons prevent exposure to surrounding areas of the body such as the head, neck and upper chest.
Why X-rays are needed
Without current x-rays it is virtually impossible to detect decay between the teeth, abscesses involving the teeth or jaws, locating teeth impacted in the jaw, following the development of primary or permanent teeth, and many other conditions of the jaws and dentition.
