Space Maintainers

When a baby tooth is lost too early, whether from decay, injury, or extraction, the surrounding teeth can shift into the empty space before the permanent tooth is ready to come in. A space maintainer is a small custom-fitted appliance that holds that space open, giving the adult tooth room to erupt where it belongs. At Brighton Family Dentistry in Brooklyn, NY, space maintainers are offered as part of a broader focus on children's dentistry.

When a Space Maintainer May Be Needed

Early tooth loss — a baby tooth is lost well before the permanent tooth beneath it is due to erupt.
Crowding prevention — neighboring teeth are at risk of drifting into an open gap.
Extraction follow-up — a tooth has been removed due to decay or injury and the space needs to be preserved.

Types of Space Maintainers

Fixed unilateral — a small band and wire attached to a tooth on one side of the gap.
Fixed bilateral — a wire spanning both sides of the arch, often used after several teeth are lost.
Removable — a retainer-like appliance that can be taken out for cleaning.

What to Expect

Placing a space maintainer is typically a straightforward, comfortable visit. Regular checkups help confirm the appliance is fitting properly and that the permanent tooth is progressing as expected, alongside routine cleanings and exams.
