Why Pediatric Dental X-Rays Matter: What Parents Should Know

 Did you know that tooth decay is the most widespread childhood disease? According to the World Health Organization, about 43% of the world’s children have decay in their baby teeth. It's an alarming number that shows just how quickly cavities can start in a young mouth.

 At Hendricks Dental Specialists, our team's goal is to keep your child's smile healthy and pain-free. While we always start with a careful visual exam, there's only so much we can see with the eye. That's where diagnostic imaging comes in.

 We know parents often have questions about the safety and necessity of imaging for their little ones. Here's what you should know about why we use this technology and how we keep your child safe during their visit.

 Are dental X-rays safe for my child?

Yes, modern dental imaging is safe. We use digital X-ray technology, which is a huge leap forward from the old-fashioned film used years ago. Digital sensors actually reduce radiation exposure by up to 90% compared to traditional film.

 To put the numbers in perspective, a single digital dental image typically exposes a child to between 0.2 and 5 microsieverts of radiation. 

That's roughly the same amount of radiation your child naturally absorbs from the environment just by living on Earth for one day. It's also significantly less radiation than they'd receive during a standard cross-country airplane flight.

 Our team follows the ALARA principle, which stands for "As Low As Reasonably Achievable." This means we only take the images that are absolutely necessary for your child's specific health needs, and we "child-size" the settings to ensure the lowest possible dose.

Why can't the dentist just look at the teeth?

A visual exam is great for checking the surfaces of the teeth, but it can't see through enamel or look between the teeth. Many childhood cavities start in the gaps between molars where toothbrush bristles can't reach.

 According to the Centers for Disease Control and Prevention, nearly 1 in 5 children aged 6-8 years have untreated tooth decay. Because baby teeth have thinner enamel than adult teeth, a tiny cavity can turn into a painful infection quickly if it isn't caught early.

 Beyond looking for cavities, these images help our team at Hendricks Dental Specialists monitor how permanent teeth are growing in. We can spot missing teeth, extra teeth, or alignment issues long before they become a problem. 

This early look is a vital part of our pediatric dentistry approach. 

New safety standards for your peace of mind

You might notice some changes during your next visit. 

In a surprising 2024 update, the American Dental Association (ADA) noted that heavy lead aprons and thyroid collars are no longer recommended for dental imaging. Modern machines are now so precise that the radiation these aprons were meant to block is nonexistent.

 In fact, bulky collars can sometimes get in the way of the beam, which might result in a blurry image that has to be taken again. By following these updated guidelines, we're able to get the clearest picture possible the first time, keeping your child's total exposure to a minimum.

We're here to make sure your child feels comfortable. If you're concerned about your child's oral health or if it's time for a checkup, our team is ready to help.
