Recently The Dr. Oz show ran a program on the increase in thyroid cancer and how the increase in thyroid cancer has increased as we have increased our radiation exposure.

Dental x-rays are radiation exposure. As in all dental recommendations at Cliff Lake Dental Care, Dr. Rauchwarter and his staff look at your individual needs for dental x-rays. We do not use dental x-rays unless we feel that the benefits of taking them for cavity detection, gum disease detection, cyst detection, abscess detection, sinus and jaw joint issues outweigh the risks of not having x-rays. The following is a list of reasons we do take x-rays:
-Show areas of decay that the doctor may not be able to see with just a visual examination, such as areas of decay that might occur between teeth
-Find decay that is developing underneath an existing filling
-Find cracks or other damage in an existing filling
-Detect possible bone loss associated with periodontal (gum) disease
-Reveal problems in the root canal, such as infection or death of the nerve
-Help your doctor plan: partial implants, orthodontic treatments, dentures, or other dental work
-Reveal abnormalities such as cysts, cancer and changes associated with metabolic and systemic diseases (such as Paget’s disease and lymphoma)
-For children, radiographs are used to watch for cavities and to monitor tooth growth and development. The doctor will use periodic X-rays to see whether a space in the mouth to fit all the new teeth, whether primary teeth are being lost quickly enough to allow permanent teeth to erupt properly, whether extra (supernumerary) teeth are developing or whether any teeth are impacted (unable to emerge through the gums). Often, major problems can be prevented by catching small developmental problems early and then making accommodations.
So what are the risks? As Dr. Oz mentioned, increasing our radiation exposure could be leading to an increase in thyroid and other cancers. However, dental x-rays pose very low exposure to radiation in comparison to other types of radiation that we are exposed to everyday. The following chart shows amounts and comparisons of radiation exposure.
The table below compares our estimated exposure to radiation from dental x-ray with other various sources. A millisievert (mSv) is a unit of measure that allows for some comparison between radiation sources that expose the entire body (such as natural background radiation) and those that only expose a portion of the body (such as x-rays).
| Source | Estimated Exposure (mSv) |
| Dental X-rays Bitewing radiographs | 0.038 |
| Medical X-rays Lower gastrointestinal tract radiography Upper gastrointestinal tract radiography Chest radiograph |
4.060 2.440 0.080 |
| Natural Cosmic (Outer Space) Radiation
Average radiation from outer space In Denver, CO (per year) |
0.510 |
| Earth and Atmospheric Radiation Average radiation in the U.S. from Natural sources (per year) | 3.000 |

As you can see, dental x-rays expose you to much less radiation than natural sources. Also, at Cliff Lake Dental Care we use digital x-ray technology. Digital dental x-rays have been shown to produce up to 80% less radiation then the traditional type of dental x-rays. We have been using digital x-rays since 2007! Since 2007 he have not been routinely using lead shield aprons during the taking of digital images due to the minimal exposure. Although this type of protection was very important in the old days of high-scatter x-ray machines, today the lead aprons offer more peace of mind than actual protection because stray radiation from modern dental x-ray machines is almost nonexistent. However, we do have lead aprons available if you would like us to use them for you, please ask!
