When your child loses a baby tooth earlier than expected, your first instinct might be to simply wait for the permanent tooth to grow in. After all, it can feel like a natural part of growing up. But that open gap in your child’s smile can quietly cause real problems over time if nothing is done to preserve it. Without the right intervention, neighboring teeth can slowly drift into that empty space, leaving little room for the permanent tooth to erupt correctly and potentially setting the stage for alignment issues down the road.
At Main Street Pediatric Dentistry of Belmont, Dr. Matthew Savage takes a prevention-first approach to every child’s dental care. As the only dentist at the practice, Dr. Matthew Savage follows each patient from early childhood through the college years, making consistent and well-informed decisions at every stage. When a baby tooth is lost too soon, space maintainers are one of the most effective tools available for keeping your child’s development on the right path.
What Is a Space Maintainer?
A space maintainer is a dental appliance that holds the gap left behind by a prematurely lost baby tooth. It keeps the neighboring teeth from shifting inward while your child waits for the permanent tooth to come in.
Fixed space maintainers are cemented in place and require no adjustment by the child or parent at home. The type recommended will depend on which tooth was lost, your child’s age and their overall stage of dental development.
Why Early Tooth Loss Matters More Than You Think
Baby teeth do far more than help your child chew and speak. They act as natural guides, holding space in the jaw for the permanent teeth that will follow. When a baby tooth is lost too early, whether from decay, injury, or a dental emergency, the neighboring teeth can shift into the open space. Over time, this narrowing can lead to crowding and misalignment that may require more extensive orthodontic treatment later on.
According to a 2025 systematic review published by the National Institutes of Health, dental space maintainers are highly effective at preventing dental misalignment following the premature loss of primary teeth. Early, proactive care is one of the best investments you can make for your child’s long-term oral health.
Signs Your Child May Need a Space Maintainer
Not every case of early tooth loss calls for a space maintainer but there are several situations where one is strongly recommended. Dr. Matthew Savage will evaluate your child’s specific circumstances, but common indicators include:
- A baby molar was lost before the permanent tooth was close to erupting
- The permanent tooth is not expected to grow in for a year or more
- Neighboring teeth are beginning to shift toward the gap
- X-rays show that the permanent tooth is still developing and will not emerge soon
A thorough dental exam is the best way to determine whether a space maintainer is the right step for your child. Dr. Matthew Savage will review current X-rays and factor in your child’s age and development before making any recommendations.
What to Expect During Space Maintainer Treatment
Getting a space maintainer placed is a comfortable, low-stress experience for most children. Dr. Matthew Savage takes precise measurements and impressions of your child’s mouth to create an appliance that fits just right.
Many dentists will take an impression of the area using alginate putty, however Dr. Savage uses an intraoral dental scanner. So no more gagging when taking impressions. Kids love it because they can watch the scan of their teeth show up on the computer screen, like magic. Once in place, most kids adapt to it quickly. Routine checkups allow us to monitor the appliance and make sure everything is progressing as it should.
When the permanent tooth begins to emerge on its own, the space maintainer is simply removed. In some cases, a space maintainer may also work alongside early orthodontics to address broader developmental concerns and set your child up for the best possible outcome.
