Overview
Baby teeth hold space for the adult teeth coming behind them. If one is lost too early, the neighbouring teeth can drift into the gap.
A space maintainer is a small, custom device that keeps the gap open. This helps the adult tooth come through in the right place.
What to know
- Holds space after early baby-tooth loss
- Stops other teeth drifting into the gap
- Custom-made and removed when no longer needed
- Can reduce the need for braces later
Common questions
Why is the space important?
If teeth drift into the gap, the adult tooth may not have room to come through.
Is it uncomfortable?
It may feel odd for a day or two, then most children forget it is there.
How is it cared for?
Brush around it gently and avoid sticky foods that could pull it loose.
When does it come out?
Your dentist removes it once the adult tooth is ready to appear.
