Average Age to Lose the First Tooth: What's Normal?

Children typically lose their first baby tooth around age 6, though the normal window stretches from about age 4 on the early end to age 7 on the later end. Some perfectly healthy children don't lose a tooth until they're 7 or even 8, while others start as early as 4 or 5.

A helpful rule of thumb dentists use: baby teeth tend to fall out in roughly the same order they came in. So a child who got their first tooth early as a baby often loses their first tooth early, too, and a "late teether" tends to be a "late loser." If your child got their first tooth at four months, don't be surprised if they're an early loser; if they didn't get teeth until they were over a year old, a later first loss is expected.

By the time most children are around 6 to 7 years old, they've usually lost their first tooth or two, and the process of swapping all 20 baby teeth for adult teeth continues gradually until about age 12 or 13.

In the vast majority of children, the bottom two front teeth (the lower central incisors) are the first to go. These are usually the first teeth to erupt in infancy, so it makes sense they're also first to be replaced.

After the lower front teeth, the typical order is:

• Lower central incisors (bottom front two) — usually first, around age 6


• Upper central incisors (top front two) — soon after, around age 6–7


• Lateral incisors (the teeth on either side of the front teeth) — around age 7–8


• First molars (back teeth) — around age 9–11


• Canines (the pointed "eye" teeth) — around age 9–12


• Second molars — usually last, around age 10–12

This order isn't rigid, and plenty of children swap a couple of teeth out of sequence. What dentists like to see is symmetry — teeth being lost in a roughly matched pattern on the left and right sides, rather than one side racing ahead while the other stays untouched for a long time.

It can look dramatic when a tooth comes loose, but losing baby teeth is a normal, well-organized biological process — not damage.

Baby teeth (also called primary or milk teeth) are essentially placeholders. They help your child chew and speak, and they hold space in the jaw for the larger adult teeth forming underneath. When an adult tooth is ready to come in, it begins pushing up toward the surface.

As it does, a natural process called root resorption kicks in: the body gradually dissolves the roots of the baby tooth above it. With its roots dissolving away, the baby tooth loses its anchor, starts to wiggle, and eventually falls out — often with very little blood and little or no pain. The adult tooth then erupts into the empty space over the following weeks.

This is why a baby tooth that falls out naturally usually has little or no root attached — the root has already been resorbed. A baby tooth knocked out early by injury, by contrast, may still have its root, which is one reason accidental early loss is handled differently.

Yes — there's a wide normal range, and timing alone rarely signals a problem. Several harmless factors influence when your child loses that first tooth:

• Genetics: This is the biggest factor. If you or your partner lost teeth early or late as kids, your child often follows a similar pattern.


• When they first got teeth: Early teethers tend to be early losers, and vice versa.


• Sex: On average, girls tend to lose teeth slightly earlier than boys.


• Overall growth: Children who are taller or heavier for their age sometimes lose teeth a bit earlier.

A child losing a first tooth at 4 or not until 7 is usually just normal variation. The key thing dentists look for is steady, symmetrical progress over time rather than one specific "correct" age.

While most timing differences are normal, a few situations are worth a professional check:

Losing a tooth very early (before age 4)
A baby tooth lost noticeably early — especially from decay, infection, or an injury rather than naturally — deserves attention. Baby teeth hold space for adult teeth, and losing one too soon can let neighboring teeth drift into the gap, potentially crowding the adult tooth that's meant to come in. The dentist may recommend a small space maintainer to preserve room.

No teeth lost by age 7–8
If your child reaches 7 or 8 with no loose or lost teeth at all, it's reasonable to ask the dentist to take a look. Usually it's just late timing and an X-ray confirms everything is developing normally. Occasionally it can point to issues like missing adult teeth, crowding, or extra teeth blocking the way — all easier to manage when caught early.

An adult tooth coming in behind a baby tooth ("shark teeth")
Sometimes the adult tooth erupts behind a baby tooth that hasn't fallen out yet, creating a double row. This is common and often resolves on its own as the baby tooth loosens, but if the baby tooth doesn't come out within a couple of weeks, the dentist may help it along.

Signs of decay, pain, or infection
Loosening should come from a normal erupting adult tooth — not from cavities or gum problems. Toothache, swelling, a dark or discolored baby tooth, or a pimple-like bump on the gum are reasons to see a dentist regardless of your child's age.

When that first tooth finally comes out, the process is usually simple and not very messy. Here's how to handle it:

1. Let loose teeth fall out naturally. Encourage gentle wiggling with clean hands, but avoid yanking. Pulling a tooth before its root has fully dissolved can hurt and cause unnecessary bleeding. It will come out on its own when it's ready.
2. Manage minor bleeding. A little blood is normal. Have your child bite down on a clean, damp piece of gauze or a tissue for a few minutes, and the bleeding should stop.
3. Rinse gently. A rinse with cool water (or mild salt water for older kids who won't swallow it) keeps the area clean.
4. Keep brushing. Your child can keep brushing as usual, just gently around the new gap.
5. Celebrate the milestone. This is where the tooth fairy tradition can make the experience fun and positive, especially for a nervous child.

If a tooth is knocked out early by an accident rather than coming loose naturally, see a dentist — unlike a permanent tooth, a knocked-out *baby* tooth is generally not re-implanted, but a dentist should still check for damage to the gums and the developing adult tooth underneath.

For some kids, a wobbly tooth is exciting; for others, it's alarming. A few simple things help:

• Explain what's happening in simple terms: a new "big-kid" tooth is pushing the little one out, and it's supposed to happen.


• Reassure them it won't really hurt — most baby teeth fall out with little or no pain.


• Don't force it. Let your child be in control of wiggling so they feel safe.


• Make it positive with a small reward or the tooth fairy tradition.


• Read a story about losing teeth — there are many children's books that normalize the experience.

Keeping the tone calm and matter-of-fact helps your child see tooth loss as the exciting growing-up milestone it is, rather than something to fear.
