Do I really need X-Rays? Yes, X-Rays are necessary for proper diagnosis and treatment planning. They are needed for diagnosing:
- Abscesses and infection
- Decay between the teeth and under existing restorations
- Periodontal (gum) disease
- Cysts & tumors
- Root Canal treatment
- Dental Implant placement
The tables below give dose estimates in millirems (mrem) for typical diagnostic radiology exams. The annual maximum allowable radiation dosage for healthcare workers is 5000 millirems. Dental x-rays are at the lowest end when it comes to effective dose.

Finally, here is the dosage received for dental x-rays. As you can see, dental x-rays have the lowest dosage, by far, when compared to the above tables.

A few other facts on random sources of radiation include:
- The average U.S. resident receives 360 millirems every year from background sources.
- If you live in a brick house instead of a wood house, you receive an extra 10 millirems per year due to radioactive materials in the masonry.
- Flying cross country in an airplane exposes you to 5 millirems due to increased altitude.
Dr. Eric Meeker gains valuable information from x-rays to aid in keeping your mouth healthy. It is not in your best interest to refuse dental x-rays due to the very small amount of radiation you receive from them. |
