Space Maintainers

When baby teeth are lost prematurely, it is usually necessary to hold the teeth on either side of the space created by the premature loss so it does not close up. If the space is not maintained, the space will close and the permanent teeth will be unable to come in properly. The replacement of primary anterior teeth for esthetics, or possibly to facilitate normal speech development, may also be indicated.

If a tooth is lost on one side of the jaw, a unilateral (one-sided) space maintainer is used. If teeth or a tooth is lost on both sides of the upper or lower arch, a bilateral (two-sided) space maintainer is used. These are described as a NANCE HOLDING ARCH for the upper teeth, or a LOWER LINGUAL HOLDING ARCH for the lower teeth.

Regular six-month checkups are recommended to make sure the appliance is still fitting properly or become loose. If you notice the new tooth erupting improperly under, or around the space maintainer, see us as soon as possible.

To avoid the cost and time of replacement, please avoid sticky foods, popcorn and chewing on ice. At night, please be certain to carefully clean around all wires, bands and other areas of the appliance, as it tends to trap food. After cleaning, please inspect the appliance carefully for damage.
