Baby teeth matter more than most parents realize
There is a common misconception that losing a baby tooth early is no big deal. It is just a baby tooth, after all. The permanent one will come in eventually.
The problem with that thinking is timing. Baby teeth are not just placeholders in name. They actively hold space in the jaw, guide the permanent teeth that are developing underneath, and keep neighbouring teeth in their correct positions. When a baby tooth is lost before the permanent tooth is ready to take over, the surrounding teeth do not stay put and wait. They drift toward the gap.
Once that drifting starts, the permanent tooth has less room to erupt. It may come in crowded, rotated, or at an angle. In some cases, it becomes impacted entirely, stuck beneath the gum line because there is no longer enough space. What started as a routine early tooth loss can become a complex orthodontic problem that takes years to correct.
Space maintainers and early orthodontic appliances exist specifically to prevent this chain of events.
What is a space maintainer?
A space maintainer is a small custom-made appliance placed in a child’s mouth after a baby tooth is lost prematurely. Its job is passive: it sits in the gap and stops the adjacent teeth from drifting into it. It does not move teeth. It does not apply pressure. It simply holds the space open until the permanent tooth is ready to emerge.
Most space maintainers used for young children are fixed, meaning they are cemented to adjacent teeth and cannot be removed by the child. This is generally preferred because fixed appliances work continuously without requiring the child to remember to wear them. Removable versions, which look similar to retainers, are sometimes used for older children who can reliably manage them.
The type of space maintainer recommended depends on:
- Which tooth was lost and in which part of the arch
- The child’s age and how long until the permanent tooth is expected to erupt
- Whether one tooth or multiple teeth are involved
- The overall state of the developing bite and jaw
A dental X-ray is typically taken to assess how close the permanent tooth is to erupting and whether the space is at risk of closing. Not every early tooth loss requires a space maintainer. Front baby teeth that are lost early usually do not need one. Back molars are the higher-risk area because molar drift happens quickly, and the consequences for spacing are significant.
Other early appliances: what they are and what they do
Space maintainers are the most commonly placed early appliance, but they are part of a broader category of interceptive orthodontic tools. Depending on what is happening in a child’s developing bite, an orthodontist in Kelowna may recommend other appliances during the mixed dentition phase when both baby and permanent teeth are present.
Palatal expanders widen the upper jaw to create more room for permanent teeth and correct crossbites. The upper jaw is made of two bones that have not yet fully fused in children, which means expansion is far more efficient and comfortable at a younger age than it would be in an adult. Addressing a narrow arch early can reduce or eliminate the need for tooth extraction later.
Habit-breaking appliances are used when habits like prolonged thumb-sucking or tongue thrusting are affecting how the teeth and jaws develop. These habits, if continued past age four or five, can create an open bite or push the front teeth forward. A simple appliance that discourages the habit during sleep can prevent the need for more involved treatment down the road.
Partial braces or limited orthodontic treatment on specific teeth are sometimes placed early to address a developing crossbite, an individual tooth that is erupting into the wrong position, or to guide jaw growth at a time when growth modification is most effective.
The goal of all of these appliances is the same: to act when the problem is small, when the jaw is still growing and responsive, and when the solution is simpler than it would be later.
When does early treatment make sense?
Not every child needs early orthodontic treatment. Many children benefit from monitoring, which means the orthodontist tracks jaw and tooth development over time and recommends starting treatment when the window is right.
The Canadian Association of Orthodontists recommends that children have a first orthodontic assessment around age seven. At this age, enough permanent teeth have come in to give the orthodontist a clear picture of how the bite is developing. Jaw growth patterns, crowding, crossbites, and bite relationships can all be evaluated before they become harder to manage.
Early assessment does not automatically mean early treatment. In many cases, the orthodontist identifies concerns to monitor and establishes a plan. In others, a short phase of early treatment at age seven to ten can meaningfully reduce what would otherwise be a more complex correction in the teenage years.
The situations most likely to benefit from early intervention include:
- A crossbite where the upper teeth bite inside the lower teeth
- A significantly narrow upper arch
- A developing underbite where the lower jaw is growing forward relative to the upper jaw
- Premature baby tooth loss in the molar region
- Persistent habits affecting bite development
- Significant crowding that may require careful management of eruption timing
If none of these are present, the orthodontist will typically recommend a monitoring schedule and reassess when more permanent teeth have come in.
What happens if you skip early treatment?
The honest answer is that for some kids, not much. Not every orthodontic problem worsens significantly if left until the teenage years. A thorough early evaluation can identify which issues genuinely benefit from early action and which are best managed later.
But for the cases that do benefit from early intervention, the cost of waiting is real. Space that closes cannot always be recovered without tooth extraction. A crossbite that persists can create jaw asymmetry over time. A narrow arch that could have been expanded easily at age eight becomes a more involved procedure at age fourteen.
The question is not whether early treatment is always necessary. It is whether your child should be assessed early enough that the right decision can be made at the right time.

We recommend an initial evaluation around age seven so that developing issues can be identified early. Our approach is honest and conservative: we recommend treatment when there is a genuine benefit to acting, and monitoring when waiting is the better strategy. We do not recommend unnecessary appliances, and we take the time to explain exactly what we are seeing and why we are recommending what we are.
