Preparing Your Child's Mouth For The Future

Dental Space Maintainers

When baby (primary) teeth are lost before the permanent teeth erupt, the space may need to be filled with a space maintainer (spacer). Not only are primary teeth used for chewing and speech development, they guide permanent teeth into the spaces where they belong.  If a spacer is not placed, shifting of the teeth can occur.  If this shifting is not controlled, the baby teeth may become crowded and cause future orthodontic problems. Spacers are removed when the new tooth erupts.

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 spacer.
  • But if space is already a problem, a spacer may be necessary.

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

Regular brushing and good oral hygiene are especially important. During your child’s regular dental check-ups, we will inspect the spacers and follow the progress of the incoming permanent teeth.
