Space Maintainers Q & A

What are space maintainers?

A dental space maintainer is a fixed or removable device that helps protect your child's bite and alignment when they have missing baby teeth. These devices hold space in the gums and bone for permanent teeth when your child has missing baby teeth due to:

  • Severe decay
  • Congenital defect
  • Oral trauma
  • Periodontal disease


RyeSmiles Pediatric Dentistry practices phase one interceptive orthodontics, which means they offer early intervention for children with significant dental issues. They utilize various fixed appliances, including, spring-loaded appliances, and space maintainers, in addition to other orthodontic services.

Why are space maintainers essential to my child's oral health?

Under normal conditions, an adult tooth is ready to erupt and fill in the gap immediately when a baby tooth is lost. When your child loses a baby tooth prematurely, adult teeth aren't ready to come in yet. When there is significant time between tooth loss and when an adult tooth erupts, your child's teeth move and shift to fill the gap.

This natural movement can cause significant alignment issues later, including:

  • Impacted teeth
  • Jaw problems
  • Crooked teeth
  • Misalignment issues
  • Speaking or eating problems


Space maintainers keep surrounding baby teeth in place by keeping pressure on the teeth, not allowing them to shift as your child grows. They keep the gap open for their permanent teeth to develop and avoid problems and expensive dental work later.

What are the different types of space maintainers?

RyeSmiles Pediatric Dentistry offers both fixed and removable space maintainers.

Fixed space maintainers

Customized fixed space maintainers are semi-permanent; they hold space for an extended time until an adult tooth begins to grow. The dental team removes the device when the permanent tooth erupts, and the appliance is no longer needed. Different types of fixed devices include band and loop, distal shoe, bilateral and unilateral appliances. Each holds space for an adult tooth in a slightly different way using wires and other materials.

Removable space maintainers

Removable space maintainers are also customized to fit your child and may include a false tooth. These are typically acrylic and removable to help maintain good oral hygiene. They are ideal for short-term treatments and older children and may not be as effective as a fixed device for some patients.

RyeSmiles Pediatric Dentistry discusses the most effective option and helps determine which device fits your child's needs best.
