Are Dental X-Rays Safe for Kids?

Yes — dental X-rays are safe for kids when they are taken for a clinical reason, with modern digital equipment, and only as often as needed. I get this question almost every week, and I understand it. You are a good parent for asking. Here is exactly how I think about it in my office.

An X-ray lets me see what my eyes cannot: decay hiding between teeth, infections at the root, extra or missing teeth, and how adult teeth are developing underneath. But here is my rule — I take radiographs only when they are clinically useful, never automatically. If your child's exam is healthy and low-risk, I do not order images just because a schedule says so. Every image has to earn its place by changing what I would do for your child.

How small is the dose, really

We use digital sensors, which need far less radiation than old film X-rays. A set of small bitewing images exposes your child to about the same radiation as a short airplane ride or a day of natural background exposure. We also use a lead apron with a thyroid collar for every image, and the beam is aimed precisely so nothing extra is exposed. I would not take an image on my own patients — or recommend one for yours — if the benefit did not clearly outweigh that tiny dose.

What X-rays help us catch early

The biggest win is catching decay between teeth while it is still small. An early spot might be treatable with gentle, non-drilling options like SDF or Curodont instead of a filling later. X-rays also show me whether there is enough space for incoming adult teeth and whether a wiggly tooth has a problem brewing underneath. That is individualized prevention — the right image, for the right child, at the right time — and it is part of every checkup decision I make.

If you ever want to talk through whether your child needs images at a visit, ask me — I will show you exactly what I am looking for and why. We are at 54 Warren Street, open Monday through Friday 8am–7pm and weekends 9am–4pm. Call 212-561-5303.

Frequently Asked Questions

How often does my child need dental X-rays?

Only as often as clinically useful. A low-risk child with healthy exams may go longer between images; a child with a history of decay needs them more often. I decide at each visit, not by a fixed schedule.

Are digital X-rays really lower dose than film?

Yes, substantially. Digital sensors need a fraction of the exposure that film required, and we add a lead apron with thyroid collar on top of that.

Can I refuse X-rays for my child?

You can always ask questions and decline. I will explain what I would be unable to see without them so you can make an informed choice.

Do you X-ray toddlers?

Only if there is a specific reason — trauma, suspected decay, or a developmental question. Routine images on a healthy toddler are not our practice.
