What Is a Space Maintainer? Treatment After Early Baby Tooth Loss

What Is a Space Maintainer?

A space maintainer is a passive orthodontic appliance — fixed in the mouth or removable — that preserves the gap left after a child loses a baby tooth early, ensuring the underlying permanent tooth has enough room to erupt. It is also referred to as a "baby tooth space maintainer" or simply "dental spacer".

Baby teeth act as natural space maintainers for the permanent teeth. When one is lost early — through extraction, trauma or decay — neighbouring teeth tilt into the gap and the opposing tooth in the upper or lower arch over-erupts. The result: insufficient space for the underlying permanent tooth and orthodontic problems later.

Following American Academy of Pediatric Dentistry (AAPD) and Turkish Society of Pediatric Dentistry (TPD) guidance, a space maintainer should be considered whenever a baby tooth is lost more than six months before the permanent tooth is expected to erupt.

When Is a Space Maintainer Necessary?

A space maintainer is not required after every tooth loss; the pediatric dentist decides based on the child's age, which tooth was lost and the radiographic assessment. The following are typical indications:

1) Baby tooth loss after trauma: Cases where a baby tooth is lost due to a fall, impact or sports injury — especially anterior incisors and molars.

2) Extraction due to early childhood caries: Baby teeth that have decayed beyond restoration and must be extracted. This is the most common indication.

3) Congenital missing tooth: In some children the permanent tooth never forms; in this case the space maintainer is used long-term, until orthodontic treatment or implant age.

4) Early loss of primary molars: Especially loss of the lower second baby molar (the "E" tooth) tends to allow the first permanent molar (the 6-year molar) to drift forward — a classic space-maintainer indication.

Types of Space Maintainers

Space maintainers fall into two main groups by mode of use and the number of missing teeth: fixed and removable. The pediatric dentist decides which type is appropriate based on clinical exam, radiographs and the child's compliance potential.

Fixed space maintainer: Bonded to a neighbouring tooth in the mouth and not removable by the child. The two most common fixed types are band-and-loop and lingual arch. A band-and-loop is used after a single tooth loss, with a band around the neighbouring primary molar and a wire loop preserving the gap. A lingual arch, used in the lower jaw when multiple teeth are lost, is banded to lower molars with a wire passing along the inside of the arch.

Removable space maintainer: An acrylic plate, sometimes containing a prosthetic tooth, that the child can take in and out. It is preferred when multiple teeth are missing or when aesthetics are a concern. Because it requires the child's compliance, it is not recommended under the age of 4.

Distal shoe (a special type): Used in rare cases where the second baby molar is lost before the 6-year molar has erupted. This treatment requires significant clinical experience.

How Is a Space Maintainer Placed? The Clinical Process

In modern pediatric practice, a space maintainer is typically placed in two appointments and is painless for the child.

Appointment 1 — Examination and impression: The pediatric dentist evaluates the need for a space maintainer through clinical exam and a panoramic radiograph. If indicated, an intra-oral impression is taken from the area of the lost tooth. For a fixed appliance, the band fit on the neighbouring primary molar is also verified.

Appointment 2 — Fabrication and fitting: The space maintainer made in the dental laboratory (typically in 7-10 days) is placed in the child's mouth. A fixed type is cemented with dental adhesive; a removable type is seated as an acrylic plate.

After placement the child usually adapts within 2-3 days. Parents are advised that the child should not bite hard on the appliance (especially the removable type) and should continue daily dental hygiene.

Follow-up: After placement, six-month check-ups are recommended. Once the permanent tooth begins to erupt, the space maintainer is removed by the pediatric dentist.

Are There Any Risks Associated with Space Maintainers?

When properly indicated and placed by an experienced pediatric dentist, a space maintainer is a safe treatment. No long-term adverse effects have been demonstrated in the scientific literature. There are some minor considerations:

Gum irritation: The band of a fixed space maintainer sits close to the gingiva, which may cause mild irritation in the first weeks. Regular brushing and oral care resolves this.

Caries risk: Plaque can accumulate between the banded tooth and the band of a fixed space maintainer. For this reason it is important that the child brushes twice a day and is followed up with professional cleaning at check-ups.

Loosening or breakage: A fixed space maintainer can rarely loosen or break; if so the pediatric dentist should be contacted promptly. With removable maintainers, the most common issue is the child taking it out and losing it.

Aspiration risk: For a fixed maintainer this is extremely rare; for a well-fitting removable type it is also minimal.

The belief that "space maintainers are harmful" is a misconception; the orthodontic problems that arise without one (crowded teeth, extraction-based orthodontic treatment) are far more significant.

Space Maintainer Pricing

In Turkey, the price of a space maintainer depends on the type used (fixed or removable), the area of the mouth, the laboratory fee and the clinic's fee schedule. The Turkish Dental Association (TDB) publishes a minimum-fee schedule each year; clinics charge in line with or above this schedule.

Important note: Under regulation, private dental fees may not be advertised. For pricing on a space maintainer it is recommended to contact the clinic directly and request a written treatment plan after examination.

Some private health insurance plans partially or fully cover pediatric dentistry treatments (including space maintainers). The Turkish public-insurance scheme (SGK) does not cover space maintainer treatment.

Space Maintainer Treatment in Ataşehir

At our clinic in Flora Residence, space maintainer treatment is planned with an experienced pediatric dentistry approach. At the first visit, a panoramic radiograph is used to assess the gap, the neighbouring teeth and the development of the permanent tooth.

The appropriate type of space maintainer (fixed or removable) is selected according to the child's age, the area of tooth loss and compliance capacity. The entire process — from laboratory fabrication to follow-up appointments — is managed within a single clinic.

If your child has experienced an early baby tooth loss, the right time for assessment is before the permanent tooth begins to erupt. You can contact us for an appointment.
