What is a Spacer?
Spacers or space maintainers are appliances that are placed when children prematurely lose a baby tooth or are missing a permanent tooth. Spacers prevent the unwanted movement or “drift” of both baby and permanent teeth. They maintain the ideal space for the developing permanent tooth, thus limiting future orthodontic problems.
Another type of spacer called a “lower lingual holder arch” or LLHA may be indicated in children with crowed lower teeth. A LLHA can help prevent further crowding and is an important aspect in early orthodontic intervention.
