Losing baby teeth is one of the more memorable events in early childhood, but the timeline varies considerably between children, and the range of what’s normal is wider than most parents expect.
This guide sets out when each baby tooth is typically lost, what that process should look like, and when the timing is unusual enough to warrant a dental review. If you’re a parent in the Woking area wondering whether your child is on track, the information below should give you a clear picture.
Why Baby Teeth Are Lost
Baby teeth, properly called primary teeth or deciduous teeth, are pushed out by the adult teeth forming beneath the gum. As the adult tooth develops, it resorbs the root of the primary tooth above it. The root gradually dissolves, the tooth becomes loose, and eventually it falls out or is removed by the child with a little wiggling.
This is a natural, orchestrated process. But it does occasionally go off-course, which is why knowing the expected sequence matters.
The Baby Tooth Loss Timeline
Children have 20 primary teeth in total: 8 incisors, 4 canines, and 8 molars. They are typically all present by around age three. Loss begins around age six and continues through to roughly age twelve, following a broadly predictable order.
| Tooth Name | Position | Typical Eruption Age | Typical Age of Loss |
|---|---|---|---|
| Central incisors | Front teeth, upper and lower | 6–12 months | 6–7 years |
| Lateral incisors | Either side of the central incisors | 9–16 months | 7–8 years |
| First molars | Back teeth, first set | 13–19 months | 9–11 years |
| Canines | Corner teeth (pointed) | 16–23 months | 9–12 years |
| Second molars | Back teeth, second set | 23–31 months | 10–12 years |
The lower central incisors tend to go first, often around six to seven. The upper central incisors follow shortly after. Most children find the process exciting rather than frightening when they know what to expect. The pattern we notice is that children whose parents have explained tooth loss in advance rarely find it distressing.
When a Tooth Is Lost Early
Early loss is usually caused by decay, trauma, or, occasionally, a developing adult tooth pushing upward before the primary root has fully resorbed. When a baby tooth is lost significantly before its expected time, the surrounding teeth can drift into the gap.
This matters because the primary teeth hold space for the adult teeth forming beneath them. If the space closes prematurely, the adult tooth may come through crowded, rotated, or impacted. In our experience, early loss of primary molars in particular is a common trigger for crowding problems that might otherwise have been avoided.
A space maintainer is a simple appliance that can be fitted to hold that gap open until the adult tooth is ready to erupt. Not every case needs one, but it’s worth a dental review fairly promptly if a back tooth is lost several years earlier than expected.
When a Tooth Is Lost Late
Some children are simply later developers. Variation of a year or even two years from the averages above is not automatically a cause for concern. But if a primary tooth is still firmly in place and the child is well past the upper end of the expected range, an X-ray is worth taking to check whether the adult tooth is developing normally beneath it.
Occasionally, adult teeth are missing entirely. Around one in fifty people are missing at least one permanent tooth, a condition called hypodontia. The wisdom teeth are most commonly absent, but any tooth can be affected. This tends to be identified during routine check-up X-rays in late childhood or early adolescence, and there are well-established options for managing it.
If your child still has a baby tooth at an age where most of their peers have lost it, bring them in. That said, don’t panic: most late teeth sort themselves out without any intervention.
What Happens When an Adult Tooth Doesn’t Arrive
You might be wondering what to do if a baby tooth falls out and weeks pass without any sign of an adult tooth coming through. In most cases, patience is appropriate. The gum tissue takes time to clear, and adult teeth often take several months to visibly erupt after the primary tooth is gone.
If six months have passed with no eruption, it’s worth returning for a check-up and an X-ray. The adult tooth may be blocked by a retained piece of primary root, by a cyst, or by a neighbouring tooth. These are all manageable situations when identified in good time.
But significant delays are relatively uncommon. For most children, the process is uneventful even if the timing doesn’t match textbook averages precisely.
The Tooth Fairy and Managing the Experience
The tooth fairy tradition exists in some form across most of the English-speaking world, and there’s nothing wrong with using it to mark the occasion positively. Some children are anxious about losing teeth, particularly the first one. Framing it as something worth celebrating, and something that every adult around them has already experienced, tends to help.
A loose tooth that hasn’t yet fallen out shouldn’t be pulled forcibly unless the adult tooth is already visibly erupting behind it and the primary tooth is causing the adult tooth to come in at an angle. In that situation, bring the child in and we can assess whether a simple removal is appropriate.
Keeping Us Involved During the Transition Years
The years between six and twelve are some of the most important in dental development. Regular check-ups during this period allow us to monitor the eruption sequence, identify crowding early, and address any problems before they become more complex.
We offer children’s dentistry in West Byfleet on a private basis, with appointments structured to allow enough time to track development properly. If you have specific concerns about your child’s tooth development, or if you’d like to book a check-up, Coniston Dental Practice in West Byfleet is here to help. Call our team on 01932 343675.
