A primary tooth is sometimes lost prematurely because of injury or tooth decay. If that happens before the permanent tooth is fully developed and ready to emerge, the nearby teeth can shift or “tip” into the space formerly occupied by the primary tooth. When the permanent tooth tries to grow into the spot, there may not be enough room. The new tooth may be unable to erupt or emerge lopsided, leading to crooked teeth. A space maintainer holds open the spot left by a primary tooth until the permanent tooth is ready to emerge. Generally it is a device that is permanently cemented in the mouth. The dentist will later remove the spacer once the permanent tooth is in its proper position.-Courtesy of the American Dental Association
