Most children lose their first baby tooth around age 6, though it’s perfectly normal for the process to start as late as age 7. From that first wiggly tooth to the last one, the full timeline spans roughly six years, with the final baby teeth falling out between ages 11 and 13.
Why Baby Teeth Fall Out
Baby teeth don’t just loosen on their own. When a permanent tooth is ready to come in, its dental follicle (the tissue surrounding it) moves toward the root of the baby tooth above it. Specialized cells then gradually dissolve the baby tooth’s root from the bottom up. As the root gets shorter and thinner, the tooth loses its anchor in the gum and starts to wobble. Eventually there’s almost no root left, and the tooth falls out with minimal effort.
This process is deliberate and well-timed. Each permanent tooth triggers root dissolving only in the baby tooth it’s meant to replace, which is why children lose their teeth in a predictable order rather than all at once.
The Typical Order and Timeline
Children have 20 baby teeth total, and they tend to fall out in roughly the same order they came in. The bottom two front teeth (lower central incisors) are usually first, followed closely by the top two front teeth. Here’s the general pattern:
- Ages 6 to 7: Lower and upper central incisors (the four front teeth)
- Ages 7 to 8: Upper and lower lateral incisors (the teeth flanking the front four)
- Ages 9 to 11: Lower canines and first molars
- Ages 10 to 12: Upper canines and remaining molars
- Ages 11 to 13: Second molars, the very last baby teeth to go
One detail that surprises many parents: the first permanent molars, which appear around age 6, don’t replace any baby teeth at all. These four molars erupt behind the existing baby teeth, in empty space at the back of the jaw. So your child gains new teeth and loses old ones at the same time during this stage.
What’s Normal and What’s Not
There’s a wide window of normal. Some children lose their first tooth at 5, others not until nearly 8. Girls tend to start slightly earlier than boys. If your child got their baby teeth early as an infant, they’ll often lose them on the earlier side too.
Losing a baby tooth before age 4 or 5, however, usually isn’t part of the natural process. The most common causes of premature loss are tooth decay and injury. Early loss matters because baby teeth hold space for the permanent teeth developing underneath. When a baby tooth disappears too soon, neighboring teeth can drift into the gap, potentially crowding the permanent tooth when it’s ready to come in. A dentist may recommend a space maintainer, a small device that keeps the gap open until the adult tooth arrives.
On the other end, some baby teeth hang on longer than expected. A baby tooth that stays well past the age when it should have fallen out is considered “over-retained.” This sometimes happens because the permanent tooth beneath it is missing entirely, is developing slowly, or is erupting at an angle that misses the baby tooth’s root. Routine dental X-rays can reveal what’s happening below the gumline and whether intervention is needed.
“Shark Teeth” and Other Surprises
Sometimes a permanent tooth starts pushing through the gum before the baby tooth has fallen out, creating a second row that looks a bit like shark teeth. This is especially common with the lower front teeth. It happens when the permanent tooth erupts slightly behind or in front of its intended position instead of directly beneath the baby tooth.
In most cases, this resolves on its own. About two-thirds of these misaligned eruptions self-correct by age 7 as the tongue naturally pushes the new tooth forward and the baby tooth loosens. If the baby tooth shows no signs of loosening after several weeks, a dentist can remove it to clear the path.
Handling a Loose Tooth at Home
The urge to help a dangling tooth along is strong, for kids and parents alike. Gentle wiggling with a clean finger or the tongue is fine and can even help the process. But pulling or forcing a tooth that isn’t truly ready can tug on sensitive root tissue that hasn’t fully dissolved yet, causing unnecessary pain and bleeding.
The best approach is patience. A tooth that’s barely hanging on will typically come out on its own during eating or brushing. When it does fall out, have your child rinse their mouth with clean water. A small amount of bleeding is normal and usually stops within a few minutes. If bleeding is heavier than expected, pressing a piece of clean gauze gently against the socket for a few minutes helps it clot.
Protecting Teeth During the Transition
The years between 6 and 13 are a vulnerable time for teeth. Newly erupted permanent teeth have thinner enamel than fully mature adult teeth, making them more susceptible to cavities during the first couple of years after they appear. This is one reason why consistent brushing and limiting sugary snacks matters so much during elementary school years.
Sports injuries are another concern during this stage. A knocked-out baby tooth generally doesn’t need to be replanted, but a knocked-out permanent tooth is a dental emergency. If your child loses a permanent tooth to an impact, place it in milk or saliva and get to a dentist as quickly as possible. The faster it’s replanted, the better the chance of saving it.
Regular dental checkups, ideally every six months, let a dentist track whether permanent teeth are developing on schedule and catch potential crowding or alignment issues early. X-rays taken during this period reveal the positions of teeth still hidden in the jaw, giving a clear picture of what’s coming next and whether anything needs attention.
