Most children lose their first baby tooth around age 6, and the process continues until roughly age 12 or 13 when the last baby molars fall out. The whole journey spans about six to seven years, with teeth falling out in a fairly predictable order that mirrors the sequence they originally came in.
The Typical Timeline, Tooth by Tooth
The lower central incisors, the two front teeth on the bottom, are almost always first to go, usually between ages 6 and 7. The upper central incisors follow close behind at 7 to 8. From there, the lateral incisors (the teeth flanking the front ones) shed next: lower laterals at 7 to 8, upper laterals at 8 to 9.
After that, there’s often a lull of a year or so before the back teeth start loosening. The first molars typically come out between ages 9 and 12, followed by the canines (the pointy teeth) at 9 to 12 on the bottom and 11 to 12 on top. The second molars, the ones farthest back, are last to go, falling out between 10 and 13 depending on whether they’re upper or lower.
Here’s the general sequence:
- Central incisors: 6 to 8 years
- Lateral incisors: 7 to 9 years
- First molars: 9 to 12 years
- Canines: 9 to 12 years
- Second molars: 10 to 13 years
These ranges come from the American Dental Association and the American Academy of Pediatric Dentistry, but both organizations note that many healthy children fall outside them. Some kids lose their first tooth at 5, others not until 7, and both can be perfectly normal.
Why Baby Teeth Fall Out
Baby teeth don’t just pop loose on their own. When a permanent tooth is ready to come in, specialized cells called odontoclasts begin dissolving the root of the baby tooth above it. This process happens in cycles of active dissolving and resting, gradually eating away at the root until there’s almost nothing anchoring the baby tooth in place. By the time your child wiggles it out, the root is largely gone, which is why baby teeth look hollow at the bottom when they fall out.
This is also why baby teeth loosen gradually over several weeks rather than all at once. The root resorption isn’t continuous. It alternates between periods of breakdown and brief repair, slowly tipping the balance until the tooth is ready to shed.
The “Extra” Molars That Don’t Replace Anything
One detail that confuses a lot of parents: around age 6 to 7, children get their first permanent molars in the very back of the mouth. These don’t push out a baby tooth. They erupt behind the last baby molar into space that was previously empty gum. Because they arrive without a dramatic wiggling-and-falling-out event, they’re easy to miss. A second set of permanent molars comes in around age 12 the same way. These are entirely new additions to the jaw, not replacements.
What Normal Loosening Looks Like
A baby tooth that’s ready to come out will wiggle more and more over a few weeks with no real pain. The gums around it should look pink and healthy, and you may even be able to see or feel the edge of the permanent tooth pushing through underneath. Kids can gently wiggle the tooth with their tongue or clean fingers, but forcing a tooth that isn’t ready can damage the gum tissue or the incoming permanent tooth.
Mild bleeding when the tooth finally comes out is normal and usually stops within a few minutes with light pressure from a piece of gauze or a damp washcloth.
When the Timing Is Off
Losing a baby tooth before age 4 is considered premature and worth a dental visit. Early loss from decay or injury can cause real problems down the line. Baby teeth hold space for the permanent teeth developing beneath them. When one disappears too soon, the neighboring teeth can drift into the gap, leading to crowding, crooked eruption, or permanent teeth that get trapped under the gum. Dentists often place a device called a space maintainer to keep the gap open until the permanent tooth is ready. Early tooth loss can also affect a child’s speech development and, for older kids, their confidence in social settings.
On the other end, some children reach age 8 without losing a single tooth. This is usually just a slower developmental pace and not a concern, but it’s reasonable to mention it at a regular dental checkup so X-rays can confirm the permanent teeth are forming normally underneath.
Signs That Something Isn’t Right
Most loose baby teeth need zero intervention, but a few situations call for professional attention:
- Pain or swelling: Significant pain, swollen or red gums, pus, or facial swelling can signal an infection rather than normal shedding.
- Trauma: A tooth knocked loose by a fall or sports injury should be evaluated even if it looks fine. The impact can damage the permanent tooth developing underneath.
- Shark teeth: Sometimes the permanent tooth erupts directly behind the baby tooth instead of pushing it out, creating a second row. If the baby tooth stays firmly in place after the permanent tooth has fully come through, it may need to be removed.
- Months of wobbling: A tooth that’s been loose for several months without progressing toward falling out may need an X-ray to see what’s going on beneath the gum line.
Fever, persistent bad breath that doesn’t improve with brushing, or discharge around a loose tooth are also signs that warrant a call to the dentist rather than a wait-and-see approach.
