Are Dental X-Rays Dangerous to Your Health?

Your dentist suggests a dental X-ray and you're wondering about the health risks? This is a common question, especially among pregnant women and parents. Here's what you need to know to understand why modern dental X-rays are considered safe.

At Cabinet Dentaire Rodde et Associés in Schifflange, Dr. Paul Balducci and Dr. Camille Rodde use radiographic imaging daily to make reliable diagnoses and offer appropriate treatments, always in compliance with safety standards.

What Is the Radiation Dose from a Dental X-Ray?

The radiation dose from a dental X-ray is very low, often lower than the natural exposure we receive every day.

For comparison:

• Single tooth X-ray (periapical): approximately 0.005 mSv

• Panoramic X-ray: 0.01 to 0.02 mSv

• Dental CT scan (CBCT): 0.05 to 0.1 mSv

• Daily natural exposure: approximately 0.008 mSv

A dental X-ray therefore corresponds to less than one day of natural exposure, making it negligible from a health perspective.

Are Dental X-Rays Risky?

Thanks to current technologies, the risks are minimal, including for more sensitive individuals.

What significantly limits exposure today:

• Digital radiography (up to 80% less radiation than before)

• Precise and targeted beam

• Rectangular collimation to reduce the exposed area

• Lead apron and thyroid protection when necessary

The ALARA Principle: A Strict Rule

Dentists apply the ALARA principle (As Low As Reasonably Achievable), which aims to reduce exposure to the strict minimum.

In practice:

• An X-ray is only performed if it's useful

• The number of examinations is limited

• Settings are adjusted to obtain a reliable image with the lowest possible dose

Why Are Dental X-Rays Essential?

Certain conditions are not visible to the naked eye. X-rays allow us to detect and assess:

• Cavities between teeth

• Infections at the root level

• Bone loss related to periodontal diseases

• Impacted wisdom teeth

• Dental fractures

• Bone quantity before implant placement

Refusing an X-ray can sometimes delay an important diagnosis.

X-Rays and Pregnancy: Is It Allowed?

Yes, if the examination is medically justified.

The irradiated area is limited to the head, and the lead apron protects the abdomen. In the majority of cases, the risk is virtually zero.

As a precaution, non-urgent X-rays can be postponed until after delivery, but an untreated dental infection represents a much greater risk.

What About Children?

Dental X-rays for children are also safe. Settings are adapted to their age and allow us to:

• Detect early cavities

• Monitor the arrival of permanent teeth

• Identify growth abnormalities

• Evaluate wisdom teeth in adolescents

Frequently Asked Questions

Can I have several dental X-rays per year?

Yes, as long as they are medically justified.

Were old X-rays more dangerous?

Yes. Current technologies have significantly reduced radiation doses.
