Space Maintainers

Primary (baby) teeth do more than help children chew. They act as placeholders that guide the developing permanent teeth into the right position as they come in. When a primary tooth is lost too early, whether from decay, injury, or an extraction, the teeth on either side may gradually drift into the empty space.

If that happens, the permanent tooth meant to fill that spot may not have enough room to come in normally. The result can be crowding, misalignment, or an impacted permanent tooth, all of which may need more involved treatment later.

A space maintainer is a passive appliance. It does not move teeth. It simply holds the gap open so the neighbouring teeth cannot drift. It is custom-made to fit your child's mouth and is removed once the permanent tooth is ready to come into that space.

No. Whether a space maintainer is needed depends on several things: which tooth was lost, your child's age, how much the jaw has already developed, and how close the permanent tooth is to coming in. The dentist uses x-rays to see where the permanent tooth is and makes a recommendation based on what they show.

For example, if a primary tooth is lost close to when it would have fallen out on its own, and the permanent tooth is near the surface, a maintainer may not be necessary.

Space maintainers are checked at each regular dental appointment to make sure they are still in the right position. They are removed once the permanent tooth begins to come into the space.

Care at home means brushing carefully around the appliance and avoiding sticky or chewy foods. Caramel, gummy candies, and similar treats can loosen or bend the appliance. If the maintainer feels loose or uncomfortable, call the office at 780-432-3430 so the dentist can check it.
