Baby Teeth Not Falling Out? When to See a Pediatric Dentist

Quick Answer: Some variation is normal, but a baby tooth that hasn’t loosened well past its usual age — or a permanent tooth erupting behind a baby tooth that won’t budge (“shark teeth”) — is worth a check. Causes range from a missing permanent tooth underneath to crowding or an obstruction. A pediatric dentist can take an X-ray, find the reason, and decide whether the baby tooth needs help coming out.

Most baby teeth fall out right on schedule, but every so often one overstays its welcome — or a permanent tooth shows up behind it. At Islands Pediatric Dentistry in Gilbert, parents ask us about this often. Here’s how to tell what’s normal and when it’s time for a visit.

What’s the Normal Timeline?

Children usually start losing baby teeth around age 6 and finish by about 12, in roughly the order the teeth came in. There’s plenty of normal variation — a few months either way is no cause for concern. The question is when a tooth is clearly behind schedule.

“Shark Teeth”: A Common Cause

Sometimes a permanent tooth erupts behind a baby tooth that hasn’t fallen out yet, creating a temporary double row — often called “shark teeth.” It looks alarming but is common, and the baby tooth usually loosens and falls out on its own within a few weeks. If it doesn’t within a month or two, we should take a look.

Why a Baby Tooth Might Not Fall Out

  • A permanent tooth erupting off to the side instead of straight up (“shark teeth”)
  • A missing permanent tooth underneath, so nothing pushes the baby tooth out
  • Crowding that blocks the permanent tooth’s path
  • An obstruction such as an extra tooth or, rarely, a cyst
  • A baby tooth fused to the bone (ankylosis)

When to See a Pediatric Dentist

Schedule a visit if a baby tooth is well past its expected loss age with no permanent tooth in sight, a permanent tooth has come in behind a baby tooth that won’t loosen after a month or two, you notice crowding or a tooth erupting in the wrong spot, or there’s pain or swelling. As pediatric specialists, we can take an X-ray to see what’s happening underneath and recommend the right step.

What We Might Do

Often the answer is simply to monitor and let nature take its course. When needed, we may gently remove an over-retained baby tooth so the permanent tooth can move into place — a quick, comfortable procedure. An X-ray guides the decision so we only intervene when it truly helps. Routine preventive visits let us track eruption as it happens.

Frequently Asked Questions

Is it normal for baby teeth not to fall out on time?

A few months’ variation is normal. But a baby tooth well past its usual loss age — or a permanent tooth erupting behind one that won’t budge — is worth a dental check.

What are shark teeth?

It’s when a permanent tooth erupts behind a baby tooth that hasn’t fallen out, creating a brief double row. It’s common and usually resolves on its own, but call us if the baby tooth doesn’t loosen within a month or two.

Why won’t my child’s baby tooth fall out?

Possible reasons include a permanent tooth erupting off to the side, a missing permanent tooth underneath, crowding, an obstruction, or a baby tooth fused to the bone. An X-ray reveals the cause.

When should I take my child to the dentist about a retained baby tooth?

If it’s well past the expected age with no permanent tooth showing, a permanent tooth is in behind it after a month or two, there’s crowding or a misplaced tooth, or there’s pain or swelling.

Will the baby tooth need to be pulled?

Often no — we monitor and let it fall naturally. When needed, we can gently remove an over-retained baby tooth so the permanent tooth can move in. An X-ray guides the decision.
