Sleep Study for Kids: What to Expect

A sleep study — the medical term is polysomnography — is an overnight test that records what happens in your child's body while they sleep: breathing, oxygen levels, heart rate, brain waves, and body movements. Nobody is asking your child to perform or fall asleep on command. The goal is simply to watch a normal night and capture the data.

As a pediatric dentist with an airway-focused approach, I refer children for sleep studies when the signs point that way: loud habitual snoring, pauses in breathing, restless sleep, mouth breathing all night, or daytime behavior that suggests poor sleep quality. Snoring in children is often a sign of a restricted airway, and a sleep study is how the medical team measures exactly what is happening.

What the night actually looks like

You go to a sleep lab in the evening — many are set up like a plain bedroom, not a hospital room. A technician places small sensors on your child's scalp, face, chest, and legs with gentle adhesive; there are no needles and nothing goes inside the body. You stay overnight in the room with your child. Most kids fall asleep a little later than usual because it is new, and that is fine — the technicians are used to it. In the morning the sensors come off and you go home.

How we use the results in my office

The sleep physician interprets the study and sends a report. If it shows a breathing-related sleep issue, the pediatrician or ENT leads the medical plan. My job starts where theirs overlaps with dentistry: I track jaw growth, bite development, and tongue posture at every checkup, because the airway shapes the arches and the arches shape the airway. When orthodontic guidance is part of the picture, our in-house orthodontist and I plan it together.

If your child snores regularly or you are worried about their sleep, bring it up at the next visit — do not wait for it to resolve on its own. We are at 54 Warren Street, open Monday through Friday 8am–7pm and weekends 9am–4pm. Call 212-561-5303.

Frequently Asked Questions

Does a sleep study hurt?

No. The sensors stick to the skin with gentle adhesive — no needles, no pain. Most kids say the worst part is feeling a little silly with all the wires.

Can I stay with my child overnight?

Yes. A parent stays in the room for the whole night at pediatric sleep labs. Bring pajamas, a favorite stuffed animal, and whatever makes bedtime feel normal.

Who orders the sleep study?

Usually your pediatrician, sometimes the ENT. I refer and coordinate from the dental side, but the medical team orders and interprets the study.

What if the study comes back normal?

That is useful information too. It tells us the airway is likely not the issue, and we keep looking — sometimes at habits, allergies, or bedtime routines.
