If your child’s tooth has come out too soon because of decay or an accident, it is important to maintain the space to prevent future space loss and dental problems when permanent teeth begin to come in. Without the use of a space maintainer, the teeth that surround the open space can shift, impeding the permanent tooth’s eruption. When that happens, the need for orthodontic treatment may become greater.
Types of Space Maintainers
Space maintainers can be made of stainless steel and/or plastic, and can be removable or fixed (cemented to the teeth).
A removable space maintainer looks much like a retainer with plastic blocks to fill in where the tooth is missing. If your child is older and can reliably follow directions, a removable space maintainer can be a good option.
Fixed space maintainers come in many designs.
A band-and-loop maintainer is made of stainless steel wire and held in place by a crown or band on the tooth adjacent to the empty space. The wire is attached to the crown or loop and rests against the side of the tooth on the other end of the space.
A lingual arch is used on the lower teeth when the back teeth on both sides of the jaw are lost. A wire is placed on the lingual (tongue) side of the arch and is attached to the tooth in front of the open space on both sides. This prevents the front teeth from shifting into the gap.
Caring for Your Child’s Space Maintainer
There are four general rules for taking care of your child’s appliance.
- Your child should avoid sticky foods, including candy and chewing gum.
- Encourage your child not to push or tug on the space maintainer with the fingers or tongue.
- Keep your child’s space maintainer clean through effective brushing and flossing.
- Your child should continue to see the pediatric dentist for regular dental visits.
