X-rays, also called radiography, are 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 abcesses.
There are three kinds of X-rays:
- Bitewings are the most conventional kind of dental X-rays and are used to spot cavities and decay.
- Periapical 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 abcesses.
- 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
There is no reason to be concerned about the health effects of dental X-rays. Most people receive more radiation from sunlight in one day than in one sitting for dental X-rays.
Exposure to radiation is brief and minimal. Safety precautions such as high-speed film minimize exposure time, and lead aprons prevent exposure to surrounding areas of the body.
