Family Dental 101: When Do Kids Lose Their Baby Teeth? What's Normal — and What's Not?

The first wobbly tooth is a pretty big milestone.
For children, it can mean excitement, a visit from the tooth fairy and plenty of checking in the mirror to see whether today is finally the day.
For parents, it can also bring a surprising number of questions.
Is this too early?
Why hasn't my child lost any teeth yet?
Should we pull a really wobbly tooth?
And why is the adult tooth coming through behind the baby tooth?
The reassuring answer is that there is quite a wide range of what's considered normal.
At Greenbank Family Dental, we're much more interested in how your child's teeth are developing overall than whether they lose a particular tooth at exactly the "right" age.
When Do Children Normally Start Losing Baby Teeth?
Most children begin losing their baby teeth at around 5–7 years of age, although some children will start a little earlier and others later.
The lower front teeth are commonly among the first to become wobbly, followed by the upper front teeth.
From there, baby teeth are gradually replaced by permanent adult teeth over several years.
By around 12–13 years of age, most children have lost the majority of their baby teeth.
But every child develops differently.
The order and overall pattern of tooth loss can sometimes tell us more than the exact age written on the calendar.
Why Do Baby Teeth Become Wobbly?
There's actually something pretty remarkable happening underneath.
As the permanent tooth develops and begins moving towards the mouth, the root of the baby tooth gradually dissolves — a natural process called root resorption.
That's when the famous wobble begins.
Once the tooth falls out, the permanent tooth can continue moving into its position.
It's one of the reasons we say baby teeth are much more than temporary teeth — they're part of the pathway that helps guide the developing adult smile.
Should I Pull My Child's Wobbly Tooth Out?
Usually, there's no need to rush it.
If a baby tooth is very loose and your child is comfortable wiggling it themselves, it's generally fine to let nature take its course.
Encourage gentle movement rather than force.
A tooth that's ready to come out will usually do so with very little discomfort.
If the tooth is painful, appears stuck, has broken, or you're simply unsure whether it should be coming out yet, we'd rather you ask us than turn it into a wrestling match at home!
What If My Child Loses a Baby Tooth Early?
This is where it's worth remembering something we discussed in our previous Family Dental 101 article:
Baby teeth matter.
They don't just help children eat and speak — they also help maintain space for the permanent teeth developing underneath.
A baby tooth that's lost naturally at the appropriate stage is very different from one lost years early because of decay, infection or trauma.
If a baby tooth is lost significantly earlier than expected, neighbouring teeth can sometimes move into the available space.
Depending on the tooth and your child's stage of development, your dentist may simply monitor the area or discuss whether anything else is required.
Help! The Adult Tooth Is Growing Behind the Baby Tooth
This one can look alarming.
Parents sometimes notice an adult tooth beginning to appear behind a baby tooth that hasn't fallen out yet — particularly around the lower front teeth.
You'll sometimes hear these called "shark teeth."
Despite the dramatic nickname, they're relatively common.
In many cases, once the baby tooth becomes loose and falls out, the tongue and normal growth of the mouth help the permanent tooth move towards a better position.
However, if the baby tooth isn't becoming loose, the adult tooth is continuing to erupt, or you're concerned about how things are developing, it's worth having it checked.
What If My Child Hasn't Lost Any Teeth Yet?
Children don't all follow exactly the same timetable.
If your child's friends are collecting tooth-fairy money while your child's teeth aren't moving at all, that doesn't automatically mean something is wrong.
Genetics and individual development can influence when teeth erupt and when they're lost.
Regular dental check-ups allow us to monitor that development over time rather than relying on a single age milestone.
If eruption appears significantly delayed or something doesn't look quite right, your dentist may recommend further investigation.
What If There's a Little Blood?
A small amount of bleeding when a baby tooth finally comes out is generally normal.
A clean piece of gauze or tissue with gentle pressure is usually all that's needed.
If bleeding is heavy, doesn't settle, or the tooth was lost because of an accident rather than becoming naturally loose, contact your dentist for advice.
What About Teeth Knocked Out During Sport or Play?
That's different from naturally losing a baby tooth.
If your child has an accident and a tooth is knocked out, chipped or moved, contact a dentist as soon as possible.
And importantly, don't try to put a knocked-out baby tooth back into the socket, as doing so may risk damaging the developing adult tooth underneath.
If you're unsure whether the tooth was a baby tooth or an adult tooth, call your dentist immediately for guidance.
Regular Check-Ups Let Us Watch the Whole Journey
This brings us back to something Dr Dan regularly emphasises with families at Greenbank Family Dental:
Preventive and proactive care is better than waiting until something becomes a problem.
Children's dental visits aren't only about looking for cavities.
They're also an opportunity to monitor:
Baby teeth
Developing adult teeth
Tooth eruption
Jaw development
Gum health
Cleaning and brushing
Early signs of decay
Changes that may benefit from monitoring
Sometimes the most useful thing we can tell a parent is simply:
"Everything looks exactly as we'd expect — we'll keep watching it."
That reassurance is valuable too.
From Baby Teeth to Adult Smiles
Losing baby teeth is one of those wonderful childhood milestones that happens gradually, one little tooth at a time.
There isn't a single perfect timetable every child has to follow.
What matters is that the overall development of your child's mouth is being monitored, their baby teeth remain healthy for as long as they're needed, and any unusual changes are identified early.
Because, as we explored in our previous Family Dental 101 article, baby teeth may be temporary — but the job they do is incredibly important.
At Greenbank Family Dental, our focus is simple:
preventive and proactive over reactive — helping today's little smiles become tomorrow's healthy adult smiles.
Frequently Asked Questions
What age do kids start losing baby teeth?
Most children begin around 5–7 years old, although there is normal variation between children.
Which baby teeth usually fall out first?
The lower front teeth are commonly among the first, followed by the upper front teeth.
Should I pull out my child's loose tooth?
Usually not. Letting a naturally loose baby tooth come out in its own time is generally best unless your dentist recommends otherwise.
Why is an adult tooth growing behind a baby tooth?
This can happen when the permanent tooth begins erupting before the baby tooth has fallen out. It often resolves as the baby tooth loosens, but your dentist can check it if you're concerned.
What if my child hasn't lost a tooth yet?
Development varies considerably. Regular dental visits allow your dentist to monitor whether the adult teeth are developing and erupting as expected.
Should I put a knocked-out baby tooth back in?
No. A knocked-out baby tooth should not be replanted because of the potential risk to the developing permanent tooth underneath. Contact your dentist promptly for advice.
