Space Maintainer

Sometimes, due to tooth decay or a traumatic injury, a child may lose a primary tooth early, before the permanent one underneath is ready to come into place.

When this happens, the dentist will consider the best way to hold the space left by the baby tooth in order to maintain a clear path for the succeeding adult tooth. While not every situation where a baby tooth is lost early needs an intervention to maintain the space, many times a small dental appliance known as a space maintainer is required to make sure the permanent tooth does not become crowded out of the dental arch or impacted by shifting adjacent teeth.

Once the permanent tooth begins to emerge, a space maintainer is no longer necessary.
