What Are Space Maintainers?
A space maintainer is a small dental device that keeps the gap open after a baby tooth is lost prematurely — to injury, decay, or other issues — holding space so the adult tooth can grow in properly. Without one, surrounding teeth drift into the gap, causing crowding, crooked teeth, and bite problems that often require braces or other treatment later.
Most are made from stainless steel or other strong, child-friendly materials, custom-fit to your child’s age, the lost tooth’s location, and their dental needs.
Fixed Space Maintainers
- Band and Loop — the most common choice for a single missing tooth: a metal band around a nearby tooth with a loop holding the space
- Distal Shoe — used when a back baby molar is lost early; guides the first permanent molar into correct position
- Crown and Loop — a crown covers the neighboring tooth with a loop holding space; ideal when extra durability is needed
- Bilateral Spacers — for older children whose front adult teeth and first molars are already in; maintains space on both sides of the mouth
Removable Space Maintainers
Removable options — typically plastic or acrylic with a wire — are used for front teeth or minor spacing, often when one or two front teeth are lost early. They’re easier to clean, but require the responsibility to wear them consistently.
The Process
- 1. Consultation — exam and X-rays determine whether a maintainer is needed and which type
- 2. Fitting — impressions for a custom fit (fixed types), or usage and care instruction (removable)
- 3. Follow-up — regular check-ups confirm fit and function and track the permanent tooth’s progress
Caring for It
- Brush and floss around the device to prevent cavities and gum issues
- Avoid sticky and hard foods — gum, caramel, and hard candies can loosen or damage it
- Call us if it feels loose or uncomfortable
- Keep regular visits for monitoring and adjustments
