Space Maintainers
When baby teeth are lost before the permanent teeth erupt, the space may need to be filled with a space maintainer. Primary teeth are not only used for chewing and speech development, but they also guide permanent teeth into the spaces where they belong, preventing shifting and protecting the mouth from crowding and future orthodontic problems. Space maintainers are removed when the new tooth erupts.​
Does every gap need to have a dental space maintainer?
Not every space needs to be filled:
-
The four upper front teeth spaces will stay open on their own. 
-
If a permanent tooth is ready to erupt, your child may not need a space maintainer. 
-
But if space is already a problem, a space maintainer may be necessary
According to the American Academy of Pediatric Dentistry, measurable space loss can occur within 6 months after premature loss of a primary molar — especially in younger children.
That means waiting “just to see what happens” can sometimes allow significant drifting before the next routine visit.
​Research in pediatric dentistry also shows that losing even 2–4 millimeters of space in a child’s dental arch can affect how permanent teeth erupt. In a child’s mouth, a few millimeters can be the difference between:
Straight eruption,
Crowding,
Or the need for future extractions during orthodontic treatment
Small space. Big impact.​
The American Association of Orthodontists emphasizes that early monitoring of tooth eruption and spacing can reduce the severity of future orthodontic problems.
Preserving space early may:
-
Reduce crowding
-
Lower the likelihood of impacted teeth
-
Decrease the need for more complex orthodontic correction later
What are dental space maintainers made of?
Space maintainers are made of stainless steel or plastic and come in two forms:
-
Fixed – cemented onto the teeth on either side of the space
-
Removable – looks like a retainer, used primarily for cosmetic space filling
