What We Saw When a Young Child Came in With Two Baby Molars Too Decayed to Keep
A young child came in to us with two back baby teeth that were past saving. Both had broken down with decay that, on the X-rays, had reached the nerve. As our Brisbane paediatric dentist explains, teeth in that state can turn sore and infected, and at this age, an early baby tooth loss like this still leaves years to go before the adult teeth are due to come through. Dr Ellie Nadian continues to explain that timing was the real issue. Baby molars hold the space for the adult teeth coming in behind them, so losing two this early can let the neighbouring teeth drift into the gap the adult tooth was meant to fill. Protecting that space is where our plan for this child began.
What an Early Baby Tooth Loss Does to the Adult Tooth Waiting Underneath
According to our Kids’ dentist, an early baby tooth loss can crowd, or even block, the adult tooth that is still forming underneath it. Under each baby molar an adult tooth is waiting, and it will not be ready to come through for years. The baby molar holds its place. Lose it too soon and the teeth on either side, along with the large adult molar that arrives at the back around age six, tend to tip and drift forward into the gap. That narrows the room the adult tooth was counting on. Without the right management, this kind of space loss can cause problems for the tooth meant to replace it. It may come through crowded, out of line, or even stuck. Putting that right can mean orthodontic treatment down the track. How much of this happens varies from child to child. It depends on which tooth was lost, which jaw it was in, the child’s age, and how soon the gap is looked after. For this young child, with two teeth gone from the lower jaw and years of waiting ahead, that was a real enough risk to plan around.
Why We Held the Space the Same Day We Removed Those Two Teeth
We held the space during the same operation for two connected reasons: to spare a young child a second anaesthetic, and to protect the gap before it had a chance to close.
One sleep, not two: the child was already asleep, so we did the planned space holding in the same sitting rather than bringing a young child back for another anaesthetic. Each general anaesthetic carries some risk, so the better plan is to finish the needed treatment in one visit rather than repeat it.
One plan from the start: the extractions and the space holding were mapped out together, so it made sense to do both while we were already there.
The timing was right: with two baby teeth gone from the lower jaw and the adult teeth still years off, this was the kind of gap that tends to close if it is left, so holding it early protected the room those adult teeth would need.
The cost of waiting: leaving it would have meant watching the space shrink, then most likely stepping in later anyway.
This was the right call for these teeth and this timing. It is not the right call for every gap, which is what the next section is about.
When We Hold the Gap and When We Deliberately Leave It Alone
Whether a gap needs holding after an early baby tooth loss comes down mostly to which tooth went and which jaw it was in. We hold some gaps and, just as deliberately, leave others alone.
Front teeth, almost always left: when a baby front tooth is lost early, we rarely hold the gap. The adult front teeth tend to find their way through on their own, and the space seldom causes a problem. For front teeth, holding the space is not usually needed unless it is purely for appearance.
Lower back teeth, often held: the lower jaw is where these gaps are most likely to close, so this is where we step in most often. Even so, it is not automatic: we weigh your child’s age, how crowded the mouth already is, and how close the adult tooth is before deciding. When a gap here does need holding, that is the job of a space maintainer.
Upper back teeth, weighed case by case: less room tends to close in the upper jaw, so we do not hold it automatically. We look at the individual mouth and the timing before deciding.
How close the adult tooth is: if the adult tooth underneath is nearly ready to come through, holding the gap adds little, so we may simply keep watch instead.
When there is no room to protect: if a child is already very crowded, holding a space may not help, and that points us toward a different plan.
For this young child, it was two lower back teeth with years still to wait, which put the case squarely in the hold-it column. But the cleanest way to sidestep the question altogether is to keep the natural tooth where we can, which is what the next child’s story is about.
A Different Child, a Different Call: When We Worked to Save the Tooth Instead
Not every badly decayed baby tooth has to come out. An older child came to us with a deeply decayed upper back baby tooth. Rather than remove it and hold the gap, we tried to keep it with a baby root canal and a crown, taking it out only if it could not be saved. A child’s own tooth holds space better than any appliance, so keeping it is the better goal. When it works, there is no gap to hold. It does not always work.
What the Months Afterwards Were Actually Like for This Family
The first few days were the quiet part. Soft food, while the numbness wore off, and a gap that felt strange in the mouth for a little while before this child stopped noticing it at all. After that, the months were mostly uneventful, which is what we want. At the checks that followed, we watched a few simple things: that the gum stayed healthy, that the space stayed open, and that the adult tooth underneath was developing on track.
It is not always that smooth. Appliances like this can work loose, come off, or be lost, and a few children find them irritating for a while. If one comes out, the gap can begin to close again, so we ask families to keep it and call us soon rather than wait. Holding the space does the one job it is there for, which is to stop the neighbouring teeth drifting in, and that reduces the chance of more involved orthodontic treatment later.
It is not a promise that the adult tooth will arrive perfectly placed, and it does not replace braces if they turn out to be needed. This child settled well, and the space has held. We would still rather a family hear that honest range than a tidy story, because not every mouth behaves the same way.
What If My Child Needs a Tooth Extraction But Is Scared of the Dentist?
A frightened child who needs a tooth out is one of the most common reasons families come to us, and there are two gentle ways we can help: happy gas and sleep dentistry in Brisbane under general anaesthesia.
Happy Gas: Taking the Edge Off, While Your Child Stays Awake
Happy gas is a blend of nitrous oxide and oxygen that your child breathes through a small nose mask. They stay awake and breathing on their own, just calmer and a little floaty, and it clears within minutes once the mask comes off. It is recognised in paediatric dentistry as a safe and effective way to ease milder anxiety and make shorter, simpler visits more comfortable. We see that play out in the chair. An older child who had just managed a calm check-up with us was a good candidate to try gas for the lighter work. The honest part is that happy gas is gentle, not strong. It leans on a child being able to settle and stay still, so for a very anxious child, an awkward tooth, or a long list of treatments, it may not be enough to finish comfortably. Sometimes we start with gas, and a child still needs sleep dentistry Brisbane.
Sleep Dentistry Through General Anaesthesia: When It Is Kinder to Do It All While Asleep
For a young child, a very frightened child, or one who needs several things done, including an extraction that would be hard to manage awake, the kindest and most predictable path is often to do everything in one visit while they are fully asleep under general anaesthesia. This happens in a hospital, with a specialist anaesthetist looking after the sleep side while we complete the dental treatment. Your child will not remember anything afterwards. Our young child was exactly this kind of situation, too young and with too much to do for an awake extraction, so the two teeth came out, and the gap was held in one visit. Gentle options like happy gas reduce, but do not remove, the need for general anaesthesia, and for these children, it remains the right tool. It is a bigger step than gas, with its own preparation, and it is a decision we make together with you. Most children wake up with the hard part behind them, and because it is still treatment under anaesthetic, we talk it through with you properly first.
Frequently Asked Questions
Does every baby tooth lost early need the gap held?
No. Whether a gap needs holding comes down to which tooth was lost, which jaw it sits in, and how close the adult tooth underneath is to coming through. Front baby teeth lost early usually need nothing held, because the adult front teeth tend to find their own way in. Lower back teeth are where room is most often lost, so they are the ones we are most likely to hold, which stops the neighbouring teeth drifting into the gap; when the adult tooth is nearly through, or a child is already crowded, we often just keep watch instead. In our chairs, plenty of early losses need nothing more than watching, which is why we weigh it tooth by tooth rather than by a blanket rule.
Does holding the space hurt him?
No. Fitting it does not hurt; in this child’s case, it was placed while they were already asleep for the extractions, so there was nothing to feel, and even when one is fitted at a normal visit, there is no needle and no drilling. For a few days afterwards, it can feel strange or a little bulky, and the tongue keeps finding it, then most children stop noticing it is there, as these fixed appliances are generally well tolerated. If it ever rubs or feels sharp, that is worth a quick check, but day to day it should not be sore.
How long does the gap need holding?
There is no set timeframe; the gap is held only until the adult tooth underneath is close to coming through, and that point differs a lot from child to child. For a young child like this one, the adult tooth that replaces a baby molar often does not arrive until around ten to twelve, so the gap can need holding for several years; for an older child whose adult tooth is already close, it may be only a year or so. We keep an eye on it at the regular checks and take it out once the adult tooth is nearly through, because by then it has done its job.
What if the space maintainer comes loose or my child loses it?
If the space maintainer comes loose or falls out, keep it if you can find it and call us soon. Once it is out, the neighbouring teeth can begin drifting into the gap within a few weeks, which is exactly what it was placed to stop, so the sooner we see your child, the better. In many cases, we can simply re-fit the same appliance; if the gap has already narrowed, we may need to regain the space first, which is a bigger job, and that is the honest reason we ask you not to wait.
Will this mean my child avoids braces later?
No. Holding the gap prevents one specific problem, the neighbouring teeth drifting in and crowding or blocking the adult tooth, and in doing so it reduces the chance of more involved orthodontic treatment from this one early loss. It does not fix the other things braces address, such as crowding from jaw and tooth size or a bite that does not meet well. So if your child would have needed orthodontics anyway for a separate reason, they still may; what holding the gap does is stop this one early loss from adding an avoidable problem on top.
What did it cost, and did Medicare or CDBS help?
It varies with how much treatment is needed, so we give you a written quote up front; for treatment under general anaesthetic, there are usually three separate fees: our dental fee, the hospital fee, and the anaesthetist’s fee. The Child Dental Benefits Schedule (CDBS) can help eligible children with basic chair-based items such as check-ups, fillings and extractions up to a capped amount over two calendar years, but it does not cover dental work done in a hospital or under general anaesthetic. Medicare usually covers part of the anaesthetist’s fee rather than the dental treatment itself, and any private health fund rebate depends on your level of cover, so it is worth checking all three with us and your fund before you book.
Can we just leave the gap and watch?
Sometimes, yes, and watching is a deliberate choice rather than a shortcut. Which way we go turns on three things: which tooth and jaw it was, how close the adult tooth underneath is, and whether there is room worth protecting. We tend to watch when drift is unlikely, such as a front tooth, an adult tooth nearly through, or a mouth already so crowded that holding would not help and a different plan is needed; we tend to hold when drift is likely, such as a lower back tooth in a young child with the adult tooth still years away. Either way, it is a call we make from the X-rays and keep under review.

This article is general information, not personal dental or medical advice, and it cannot account for your child’s specific situation. Every child’s mouth, bite and stage of development is different. No outcome is guaranteed, and the right call for your child can only come from an in-person examination and the appropriate X-rays with a registered dental practitioner. If your child has dental pain or swelling, or a knocked-out or badly broken tooth, please treat it as something to act on promptly and book in or seek urgent care.
Is Your Child’s Gap One to Hold, or One to Watch?
Most early losses turn out fine with nothing more than watching. A smaller number genuinely need the gap held, and the only way to know which is your child’s is an X-ray and a proper look. We will tell you straight, hold the space only when it earns its place, and never push an appliance your child does not need.
According to Brisbane Dental Sleep Clinic, for anxious patients, those with additional needs, or those facing lengthy treatment, completing care in a single visit under general anaesthesia can be a gentler option. If that suits your situation, we will discuss it with you first.
