The tooth and the timing
Tell us whether the tooth was extracted, lost in an injury, or came out on its own far too early, and roughly when. Previous records are useful. Together they show how this gap fits your child’s stage of development.

“Let’s keep an eye on it” can sound vague. For a child from Puslinch with a baby tooth lost early, we explain when watching the gap is the right call, when a space maintainer makes more sense, and exactly what each check is looking for.
Parents are sometimes surprised when a dentist looks at an early gap and suggests coming back in a few months instead of fitting something. That can feel like nothing is happening. In fact, monitoring is an active choice with its own checkpoints, and for many children it is the most sensible plan.
The reason a gap is watched at all is that teeth next to a missing baby tooth may lean into the opening before the adult tooth erupts. Our job is to judge how likely that is. We consider which tooth is gone and for how long, the room that remains, the development of the permanent tooth, and your child’s oral health and needs. Some situations call for observation; others for a space maintainer or for a specialist’s view.
Should an appliance turn out to be the better choice, it comes with work: daily cleaning, agreed reviews, and a planned adjustment, replacement, or removal later. Either way, you should understand what is being checked, why, and what would make the plan change.

Whether to watch or act depends on a handful of details. You do not have to judge the gap yourself; just share what you know.

Imaging may be suggested to check the permanent tooth and nearby structures, because age cannot reliably predict eruption. Ask what an image would answer and whether it could move the plan from watching toward an appliance, or the other way.
An appliance adds surfaces to clean. Mention decay, brushing difficulty, habits, or support needs. These details sometimes make observation the more practical route, or suggest another approach entirely.
A gap from a recent fall or knock should have the injury checked before anything else. Questions about space can wait until teeth and gums have been assessed.
If monitoring is not enough, a maintainer is generally used to stop the surrounding teeth from shifting into the space. It keeps room that exists; it does not create room that has been lost. Recovering space is a separate, orthodontic goal, so ask which applies.
An appliance has its own risks. Left without review, it may loosen, break, collect plaque, irritate the gum, or get in the way of the tooth trying to come through. It does not guarantee ideal eruption, and orthodontic assessment may still come up later. That trade-off is part of why watching is sometimes preferred.
Patient information: AAPD — developing dentition and space maintenance
If the plan moves from watching to an appliance, the dentist should explain what changed and how it relates to the missing tooth and your child’s development. Ask what drift the device is intended to prevent.
Monitoring visits check spacing and eruption; appliance reviews also look at the device and its supporting teeth. Make sure you know the date of the next one and who is responsible for it. Whether there is hardware in the mouth or not, no plan should run without checkpoints.
When the picture is more complex, a pediatric dentist or orthodontist may help. Ask what a referral would add and how records will be passed along, so the plan covers the whole growing mouth.
Any appliance follows from the findings and from what your household can manage. If one is suggested, ask whether it is fixed or removable and what that means at home.
We examine the gap and neighbouring teeth, review the history, and may suggest imaging for a specific eruption question. This first look gives us something to compare against at later visits. Mention any soreness or change you have noticed.
We explain what observation would track and what a suitable appliance would aim to do, including limits and the effort involved. If space has already narrowed, an orthodontic opinion may be the better step. Either way, the next checkpoint is agreed.
Some designs need impressions or measurements first. At fitting, the clinician checks how the device rests on its anchor teeth and beside the gum. Your child can describe anything that feels odd, and before leaving you will have a number to call if soreness lingers in the following days.
Each review compares the gap, the neighbouring teeth, and eruption with the last visit, and for an appliance, its condition too. We show you how to clean around any device and explain what to do if it loosens or breaks.
Monitoring needs little more than good brushing and noticing changes. A fixed or removable appliance needs its own care, so follow the instructions you were given.
Brush the teeth around the gap well. With an appliance, use the cleaning method we demonstrated and ask about reaching bands or wires. Tell us about any spot that stays tender.
It is fine to look at the gap now and then, and to note any change for the next visit. With an appliance, discourage pushing or pulling, follow food advice, and never bend, tighten, or glue anything.
Keep each checkpoint even if nothing looks different. Mention a new tooth or a shift in the appliance. Growth changes what is needed, and any new step is decided at a review.
Every child develops differently. Ask about your own child’s gap and what is being tracked, rather than comparing with another child.
Get in touch with our Bronte Street practice to have an early gap assessed or an existing appliance checked. Bring the approximate date of tooth loss and any earlier advice so we can set a clear baseline.
Monitoring alone may be the right plan. Advice and referral depend on your child’s findings and development.
