Space Maintainers

If a baby tooth is lost early, the neighbouring teeth drift into the gap and the permanent tooth underneath is left without room. A space maintainer holds that room open.

Average duration40 minutes

Baby teeth are not only for chewing; they also hold the place for the permanent tooth beneath. The gap left by a baby molar lost early starts to narrow within months — and years later that shows up as crowding and a need for orthodontics.

The process

  1. Examination and X-ray: seeing where the permanent tooth is
  2. Taking an impression
  3. The maintainer is made in the laboratory and fitted
  4. Check-ups every six months; removed when the permanent tooth starts to come through

When it is not needed

If the permanent tooth is close to erupting, no maintainer is fitted — the X-ray shows that. The decision follows root development on the film, not the child's age.

This page is general information and does not replace a dental examination. Whether the treatment suits you, and the method and duration, are decided only after an intraoral examination and radiographic assessment.

After treatment

There is a settling-in period of a few days; avoid sticky and very hard food. Brush around the maintainer as well. A check-up every six months is essential.
