Are Dental X-Rays Safe for Kids? How They Help Oral Health

Dental X-rays are an important part of monitoring your child’s oral health. They enable us to observe how teeth are developing beneath the surface, detect potential problems that are not visible to the naked eye, and ensure that permanent teeth are positioned to erupt correctly. Understandably, many parents have questions about the safety and necessity of dental X-rays for children.

At the Center for Pediatric Dental Health, your child’s health and well-being are our top priority. We take every precaution to minimize exposure while making sure we gather the information needed to provide safe and effective care.

Dental X-Ray Machines: What They Really Do

When people think of X-rays, they often picture large machines found in hospitals or depicted in movies. Dental X-rays are very different. The equipment is small, open, and designed specifically for comfort and precision in a dental setting. Modern machines allow us to position the device carefully so that only the necessary area is exposed.

Are Dental X-Rays Safe for Kids?

One of the most frequently asked questions we receive is whether radiation from dental X-rays can harm a child. The short answer is that radiation exposure from dental X-rays is very low, particularly when compared to many familiar everyday sources.

Dental X-Ray Radiation Compared to Everyday Exposure:

A dental X-ray typically uses 0.5–4 millirems, depending on the type and number of images taken.
A chest X-ray uses about 10–15 millirems.
The average person is exposed to approximately 620 millirems per year from both natural and man-made sources in the environment.

Another way to think about it: a single dental X-ray may expose your child to about the same radiation as they would get on a short airplane flight.

We also employ protective measures, such as lead aprons and thyroid shields, to further reduce exposure. While no medical procedure can ever be considered entirely risk-free, dental X-rays are considered a safe and effective tool when used appropriately.

How Often Should Kids Get Dental X-Rays?

The American Dental Association (ADA) and American Academy of Pediatric Dentistry (AAPD) recommend that X-rays be prescribed based on each child’s individual needs. Factors such as age, cavity risk, and dental development all play a role in determining the likelihood of cavities.

Children who are more prone to cavities may benefit from X-rays every 6 months.
Children at lower risk may only need X-rays every 1–2 years.
On average, many children receive X-rays every 12–18 months.

Your child’s dentist will recommend a schedule that balances safety with the need for careful monitoring.

At What Age Should a Child Start Getting X-Rays?

Children typically begin having dental X-rays around age 5–6, when permanent teeth are starting to develop under the gums. In some cases, X-rays may be recommended earlier if there are specific concerns, such as possible decay or an infection.

Types of Dental X-Rays

There are several types of dental X-rays, and each serves a different purpose:

Bitewing – Shows the crown of the tooth and surrounding bone. Helps detect cavities, weakened enamel, and infection.
Periapical – Shows the entire tooth from root to crown, as well as the surrounding bone.
Occlusal – Shows an entire arch of teeth to check how they fit together.
Panoramic – Provides a broad view of all teeth, jaws, and surrounding structures.
Cephalometric – Shows the profile of the teeth and jaw in relation to the head.
Cone Beam CT (CBCT) – Creates a 3D image of the teeth and jaws, used for more advanced treatment planning and diagnosis.

FAQs About Dental X-Rays for Kids

Does my child need dental X-rays?

X-rays enable dentists to visualize teeth that are still developing below the gums, assess alignment, and detect issues such as cavities or weak enamel that may not be visible otherwise.

Do dental X-rays cause cancer?

Current research shows that when dental X-rays are used appropriately and in moderation, the risk is considered extremely low. Radiation exposure from modern dental X-rays is minimal compared to the radiation from everyday environmental sources.

Do kids still need X-rays if they get 3D dental scans?

Yes. Digital scans help map the surfaces of teeth and gums, but they cannot show what is happening beneath the surface, which is where X-rays are important.

Can I refuse dental X-rays for my child?

Yes. As a parent, you always have the right to ask questions or decline treatment. We will gladly discuss your concerns, explain why we may recommend X-rays, and work with you to find the safest approach for your child’s care.
