Your child’s dental care wouldn’t be the same without x-ray imaging. It’s one of our best tools for finding and treating tooth decay.
But since x-rays emit radiation, is your child in any danger when they’re exposed?
X-rays, an invisible form of electromagnetic energy, will form images on exposed film after passing through the body. Because it takes longer for x-rays to pass through dense tissue like teeth and bones, the corresponding areas appear lighter on the film than less dense tissue like the gums. We can detect decay because the diseased tooth structure is less dense and thus appears darker against healthier tooth structure.
The downside of x-rays, though, is the radiation they emit could potentially alter cell structure and increase the risk of future cancer, especially with children. That’s why we follow a principle known as ALARA when using x-ray imaging. ALARA is an acronym for “as low as reasonably achievable,” meaning the doses for an x-ray session will be as low as possible while still gaining the most benefit.
Advances in technology, particularly the development of digital processing, has helped reduce the amount of radiation exposure. We’re also careful with what types of x-rays we use. The most common type is the bitewing, a device with the film attached to a long piece of plastic that the child holds in their mouth while biting down.
Depending on the number of our patient’s teeth, we can usually get a comprehensive view with two to four bitewings. A typical bitewing session exposes them to less radiation than what they’re receiving from natural environmental background sources each day.
Keeping the exposure as low and as less frequent as possible greatly reduces health risks while still getting the full benefit of early decay detection. Still, if you have concerns about your child’s x-ray exposure, we’ll be happy to discuss our approach and all the precautions we take using x-ray imaging.

Like any parent you want your child to grow up healthy and strong. So be sure you don't neglect their dental care, a crucial part of overall health and well-being.
The most important part of this care is prevention — stopping dental disease and other problems before they do harm. Proactive prevention is the best way to keep their teeth and gum growth on the right track.
Prevention starts at home with a daily habit of brushing and later flossing. In the beginning, you'll have to brush for them, with just a smear of toothpaste on the toothbrush. As they get older, you can teach them to brush for themselves, graduating to a pea-sized dose of toothpaste.
It's also important to begin regular dental visits around their first birthday. Many of their primary (baby) teeth are coming in, so regular cleanings and checkups will help keep tooth decay in check. Early visits will also get them used to seeing the dentist and hopefully help stimulate a lifelong habit.
These visits have a number of purposes. First and foremost is to monitor dental development and early detection of any emerging problems, like a poor bite. Catching problems early could help reduce or even eliminate future treatment.
Some children are also at greater risk for tooth decay and could benefit from applications of topical fluoride, a mineral that strengthens tooth enamel, or a sealant to help protect the teeth. This is especially helpful in preserving primary (baby) teeth: early loss of a primary tooth could disrupt the permanent tooth's eruption and cause a poor bite.
Your child's dental visits could also benefit you as their caregiver. You receive regular feedback on how well your child's teeth and gums are developing, and the effectiveness of their oral hygiene. You also get answers to your questions about their oral health: the dentist's office is your best source for advice on teething, diet and other issues.
Together, you and your dentist can provide and maintain the best conditions for your child's dental development. The result will be the healthiest mouth they can have as they enter their adult years.
