X-Rays Are Safe for Your Kids!

Posted in Digital X-Rays

X-rays work based on the fact that body tissues absorb the energy in different ways. X-rays easily pass through skin and muscle, but teeth and bone show up because they are much harder.

This makes x-rays extremely useful in dentistry. Dental patients of all ages need x-rays from time to time.

But given the fact that radiation poses the risk of cancer, are x-rays really safe for kids?

Why Your Dentist Needs X-Rays

Why take this risk at all?

X-rays help out by:

  • Revealing key anatomical details
  • Showing cavities in-between teeth
  • Planning effective dental treatment
  • Tracking and predicting tooth development
  • Checking for bone diseases

Without x-rays, your dentist may as well work on your child’s teeth blindfolded.

Precautions Are a Must!

Kids are given the lowest and most infrequent doses of x-rays possible. They are also required to wear a heavy lead apron with a collar to protect their bodies from unnecessary exposure.

How Often Are X-Rays Necessary?

As long as x-ray exposure is kept to a minimum, then routine x-rays pose no harm. The small risk is outweighed by the massive benefits that x-rays provide.

The smaller the body, the lower the exposure should be. Your dentist may wait to take x-rays on your child until:

  • A serious problem or emergency arises
  • He or she is old enough to sit still for their first routine dental x-ray examination
  • It’s time to check on tooth development progress

After that, your dentist may want to take x-rays every 1 or 2 years to watch for cavities. Office policies differ, so check with your dentist on the standards and procedures in your local dental office.

Your Child’s First Dental X-ray

When you take your son or daughter to the dentist for the first time, you might be a bit surprised if an x-ray needs to be taken. After all – aren’t x-rays just for diagnosing cavities? Not necessarily.

Your child’s x-rays show the dentist many important pieces of information that impact your son or daughter’s future smile. For example, the x-rays are used to inspect the eruption patterns of their adult teeth.

Even at a very young age, the adult teeth are beginning to develop. If a tooth is missing, proactive steps can be taken to extend the life of the temporary baby tooth.

Sometimes things such as cysts or tumors may be seen in and around the mouth with diagnostic x-rays. Although these aren’t quite as common, routine radiographs can identify the concern well before other types of symptoms ever develop.

Of course, x-rays are also used to screen for cavities. Although baby teeth fall out and are eventually replaced with permanent teeth, they still need to last for several years. Unfortunately cavities spread very quickly through primary teeth, because they are not as dense as adult teeth. This allows a small cavity in one tooth to quickly become large, create a dental abscess, spread to adjacent teeth, or even infect the underlying adult tooth.

Most children benefit from routine radiographs every 6 to 12 months, depending on the child’s age and their current oral health. The size and number of x-rays will also vary. In most cases, x-rays are usually taken beginning around age 2.

If your child has never had dental x-rays taken, it’s time to schedule a check-up!
