Why Your Child Might Need a Space Maintainer in Canada
When a baby tooth is lost early, nearby teeth can start drifting into the empty space. That may block the permanent tooth trying to come in later and lead to crowding. A space maintainer is a simple device that holds the gap so adult teeth can erupt in the right spot. The key to success is choosing the right type and fitting it to your child’s growth and habits through a personalized plan.
Do space maintainers help after early baby tooth loss?
Yes. A space maintainer is a small device that preserves the gap after a baby tooth is lost too soon. With a personalized plan—based on your child’s age, tooth development, and daily habits—it helps prevent shifting, crowding, and later orthodontic problems.
What is a space maintainer?
A space maintainer is a small, custom device that keeps the space open after a baby tooth is lost before its time. Think of it as a placeholder that stops the other teeth from tipping or moving into the gap. It helps adult teeth erupt in the right place, reducing the need for complex orthodontics later. If you’d like a quick refresher on why baby teeth matter so much for chewing, speech, and guiding adult teeth, see why baby teeth matter.
When might your child need one?
Your child may need a space maintainer if a baby tooth is lost months (or years) before its permanent replacement is ready. Common reasons include:
- Tooth decay or extraction
- Injury or trauma during sports or play
- Adult tooth that never formed (congenital absence)
Early tooth decay is a leading cause of premature tooth loss. If you’re noticing frequent cavities or sensitivity, take a look at these common dental problems in children and how to prevent them. In Canada, dentists also see kids who chip or lose teeth in hockey or other contact sports, which is another reason space maintainers are often needed.
Types of space maintainers (and how dentists choose)
Your child’s dentist will recommend a type based on age, which tooth is missing, bite, oral habits, and how responsible your child is with removable devices. The main options are:
Fixed unilateral
This device holds space on one side of the mouth, usually anchored to a nearby tooth. It’s a good choice if only one tooth is affected and your child would do better with a device that stays put.
Fixed bilateral
Used when more than one space needs to be maintained or when support across both sides is better for stability. These are common for back teeth losses in the lower jaw.
Removable
These look a bit like a small retainer. They can be taken out for cleaning, but they only work if your child wears them as directed. Some children love the independence; others lose them in lunch bags. Your dentist will help you decide.

Why a personalized plan matters
No two kids have the same growth pattern, eruption timing, or habits. A one-size-fits-all device can rub, break, or simply not fit well after a few months of growth. A personalized plan means:
- Better fit and fewer sore spots, which improves day-to-day comfort
- Lower risk of teeth drifting or crowding as your child grows
- Fewer emergency repairs and fewer missed school days
- Shorter future orthodontic treatment or sometimes avoiding it completely
Personalized planning also matches your child’s growth to the best time for orthodontic checks. If you haven’t scheduled one yet, most dentists suggest an early orthodontic evaluation by age 7.
Real-life example
Emma lost a lower baby molar at age six after a fall on the playground. Her dentist reviewed X-rays, checked how her top and bottom teeth met (her bite), and noted a mild thumb-sucking habit. Together, they chose a fixed unilateral space maintainer so it couldn’t be removed during the day. The dentist showed Emma how to brush around the bands, and the family used a small calendar to track care at home. Her adult tooth erupted on time, in the right place, and Emma avoided crowding that could have required braces later.
What to expect in the process
- Consult and X-rays. The dentist confirms that a spacer is needed and chooses the best style for your child’s mouth, age, and habits.
- Impressions or digital scans. These create a custom fit so the device is secure and comfortable.
- Fitting and instructions. The dentist places the device and teaches your child how to clean around it. If it’s removable, you’ll get wear-time instructions.
- Follow-ups. Short check-ins ensure the device still fits as your child grows and that no parts are rubbing or catching food.
- Removal. When the permanent tooth is ready to erupt, the space maintainer is removed in a quick, simple visit.
Care and day-to-day tips (kid-tested and parent-approved)
- Brush carefully around bands, wires, and the gumline twice a day. A small, soft-bristled brush helps get around the parts.
- Floss daily. If there’s a band, a floss threader makes it easier to get between teeth.
- Skip sticky, very hard, or chewy foods (taffy, caramels, hard candies, ice). These can bend wires or pull on bands.
- Wear a sports mouthguard for hockey, basketball, and other contact sports to protect the device and teeth.
- Watch for trouble signs: soreness that doesn’t fade in a few days, broken parts, or a loose band. Call your dentist for a quick fix.
Comfort, speech, and eating
Most kids adjust to a space maintainer in a few days. Some feel mild pressure on the first day or two. Speech may sound different for a week while the tongue gets used to the new shape in the mouth. If your child is self-conscious, remind them this is temporary—and that the device is helping their grown-up tooth come in straight.
Insurance and costs in Canada
Many Canadian dental plans include at least partial coverage for pediatric space maintainers under “basic” or “orthodontic appliance” benefits. Plans vary, so ask the office for a pre-determination. If you don’t have insurance, ask about payment options. Because maintainers can lower the need for later orthodontics, many families see them as a cost-saving step.
Prevention still matters
Even with a space maintainer, daily habits protect your child’s mouth. Keep sugar exposures low, use fluoride toothpaste, and see your dentist on time. If you’re looking for a friendly primer on kids’ dental health, this guide to common dental problems in children is a helpful place to start.
Conclusion
Space maintainers do quiet but important work. They hold the line after early baby tooth loss so adult teeth can erupt in the right place. The best results come from a personalized plan—matching the right device to your child’s growth, bite, and daily habits—plus simple care at home and regular check-ins. That’s how you protect today’s smile and tomorrow’s.
FAQ
Is a space maintainer really necessary?
Often, yes. Without it, nearby teeth can drift into the gap and block the adult tooth, leading to crowding or bite issues. A quick assessment tells you if your child needs one now or if monitoring is enough.
How long will my child wear it?
Usually until the adult tooth is close to erupting. That can be months or longer, depending on your child’s age and which tooth is missing. Your dentist will check progress at routine visits.
Does it hurt or affect speech?
The fitting isn’t painful. Children may feel mild pressure for a day or two. Speech can sound different briefly while the tongue adapts. Most kids adjust within a week.
How do we clean it, and what can my child eat?
Brush around the bands and gumline twice a day and floss daily. Avoid sticky, very hard, and chewy foods that can bend wires or loosen bands. Rinse after snacks. Removable devices should be brushed and stored in their case.
What if it breaks or comes loose?
Call your dentist soon. Save any broken parts if possible. Do not try to bend or fix the device at home. Quick repairs help prevent shifting.
How much does it cost in Canada, and is it covered?
Costs vary by device type and clinic. Many Canadian plans cover part of the cost under basic or orthodontic appliance benefits. Ask your dentist for a pre-determination so you know your coverage before starting.
