Dental space maintainers are devices used to leave enough space open for permanent teeth to grow in after baby teeth are lost prematurely. Space maintainers help to maintain the space previously occupied by the missing tooth and works to avoid further space loss. A fixed space maintainer is a semi-permanent tooth fixture that keeps enough space open for the adult tooth to grow in. After the permanent tooth has grown in, the maintainer can be removed. A removable space maintainer can be a good option if your child’s tooth is almost ready to grow in. Space maintainers are made of stainless steel or plastic, and they can be removable or fixed with dental cement. Space maintainer guides the permanent teeth into their proper position, preventing the teeth from shifting into a space reserved for other teeth.
