Most children lose their first baby tooth around age 6, though some kids start as early as 5 or as late as 7. The process then continues for several years, with the last baby teeth typically falling out by age 12 or 13. If your child is in that window and you’ve noticed a wobbly tooth, everything is likely right on schedule.
Why Baby Teeth Fall Out
Baby teeth don’t just loosen on their own. The process starts when the permanent tooth developing beneath the gum begins pushing upward. As it does, the body sends specialized cells to gradually dissolve the root of the baby tooth above it. This root-dissolving process uses the same biological system the body relies on to remodel bone throughout life. Over weeks or months, the root gets shorter and shorter until there’s almost nothing anchoring the baby tooth in place. That’s when your child feels it start to wiggle.
This is also why a baby tooth that falls out naturally looks hollow at the bottom. The root has been almost entirely reabsorbed by the time it comes loose.
The Order Teeth Fall Out
Baby teeth tend to fall out in roughly the same order they came in. The bottom front teeth (lower central incisors) are almost always first, loosening between ages 6 and 7. The top front teeth follow, typically between 7 and 8. From there, the pattern moves outward and backward through the mouth over the next several years.
Here’s the general timeline based on data from the American Academy of Pediatric Dentistry:
- Lower central incisors: 6 to 7 years
- Upper central incisors: 7 to 8 years
- Lower lateral incisors: 7 to 8 years
- Upper lateral incisors: 8 to 9 years
- Lower canines: 9 to 11 years
- Upper first molars: 9 to 11 years
- Lower first molars: 10 to 12 years
- Upper canines: 11 to 12 years
- Upper second molars: 9 to 12 years
- Lower second molars: 11 to 13 years
These ranges overlap quite a bit, and individual kids vary. A child who got their baby teeth early often loses them early too. Girls also tend to lose teeth slightly ahead of boys. The key thing to watch is whether teeth are falling out symmetrically: if the lower left central incisor falls out, the lower right one should follow within a few months.
What to Do With a Loose Tooth
Once a tooth starts wiggling, the best approach is usually patience. Most baby teeth come out on their own within a few weeks of getting noticeably loose. Your child can gently wiggle it with their tongue or clean fingers, and that’s perfectly fine. Encouraging them to wiggle it helps the process along without forcing anything.
What you want to avoid is pulling a tooth that isn’t ready. If it takes real force to remove, the root probably hasn’t dissolved enough yet, and yanking it can cause unnecessary pain, bleeding, or damage to the surrounding gum tissue. A tooth that’s truly ready to come out will need barely any effort. If a tooth has been loose for more than a couple of months without progressing, or if it’s causing your child significant discomfort, a dentist can evaluate whether it needs a little help.
When Early or Late Tooth Loss Is a Concern
There’s a wide range of normal. Some 5-year-olds lose a tooth, and some 7-year-olds haven’t lost any. Neither scenario is automatically a problem. Late tooth loss often just means the permanent teeth are developing on a slower timeline, which a dentist can confirm with an X-ray.
Very early tooth loss is more worth paying attention to. A child losing teeth before age 4, especially without any trauma like a fall, warrants a dental visit. Premature loss of baby teeth can occasionally signal underlying health conditions affecting bone metabolism or immune function. These situations are uncommon, but early evaluation matters because some of the conditions involved need prompt treatment. A tooth knocked out by an injury is a different story and isn’t a sign of any systemic issue, though you should still have a dentist check that the permanent tooth beneath it wasn’t affected.
Protecting the New Permanent Teeth
The permanent teeth that replace baby teeth are the ones your child will have for life, and they’re most vulnerable right after they come in. Newly erupted teeth have thinner enamel that hasn’t fully hardened yet, making them more cavity-prone during their first year or two in the mouth.
One of the most effective protective steps is dental sealants, a thin coating applied to the chewing surfaces of the back molars. The American Dental Association recommends sealants on both primary and permanent molars for all children. Studies involving nearly 2,000 participants found that kids who received sealants had a 73% lower risk of developing new cavities on those surfaces compared to kids who received fluoride varnish alone. Sealants can even stop early, non-cavitated decay from progressing.
The first permanent molars come in around age 6, often before any baby teeth have fallen out. These molars erupt behind the existing baby teeth rather than replacing them, so parents sometimes don’t realize they’re permanent. They’re prime candidates for sealants as soon as they’ve fully emerged. The second set of permanent molars arrives around age 12 and benefits from the same treatment.
The Awkward In-Between Stage
Between roughly ages 6 and 13, your child will have a mix of baby teeth and permanent teeth in their mouth at the same time. This “mixed dentition” phase is completely normal and explains why kids’ smiles often look a little uneven during elementary school. Permanent teeth are larger and slightly more yellow than baby teeth, so the contrast can be striking when they’re sitting side by side.
It’s also common for permanent teeth to come in slightly crooked or crowded, especially the upper front teeth. In many cases, the teeth straighten on their own as the jaw grows and neighboring teeth emerge. Orthodontic evaluation is typically recommended around age 7, not necessarily to start treatment, but to identify any issues that would benefit from early intervention versus those that will resolve with growth.
