Space Maintainers & Palatal Expanders Cost in 2026
A space maintainer costs about $200-$800 and holds the gap when a baby tooth is lost early, preventing far costlier orthodontics later. A child's palatal expander costs $1,000-$3,000 and widens a narrow upper jaw between ages 7 and 10. The chart below puts both on one scale.

These appliances differ widely in price because they do very different jobs — a simple band-and-loop holds one gap, while an expander remodels the jaw. The ranges below reconcile 2024-2026 fee data against AAPD guidance and FAIR Health.

Space maintainers: the place-holder
A space maintainer looks like a small metal band with a loop. It saves the spot left by a baby tooth so the adult tooth can erupt straight:
The procedure — two visits (impressions, then cementing), no injections.
Comfort — painless; it feels like food caught between teeth for a day or two.
Duration — it stays until the permanent tooth starts to poke through, often 1-3 years.
Why it saves money: skip it and the molars shift, trapping the adult tooth. Fixing an impacted tooth later means surgical exposure ($1,500) plus full braces ($6,000) — roughly $7,500 versus a few hundred dollars now.
Palatal expanders: the jaw-widener
A child's expander is "Phase 1" orthodontics:
The window — best between ages 7 and 10, while the mid-palatal suture is soft. After about age 12 it fuses and expansion needs miniscrews or surgery.
The routine — a parent turns a small screw nightly for about two weeks.
The sign — a temporary gap opens between the upper front teeth. That is good: it shows the bone is widening, and braces close the gap later.
Insurance and how to save
Space maintainers — usually well covered (often 100% under code D1510 for children under 14) because they are preventive.
Expanders — generally classed as orthodontics, so they fall under the limited ortho rider (about 30%-50%, lifetime cap), not full preventive coverage.
HSA/FSA — both are IRS-eligible expenses, so pre-tax dollars lower the real cost.
Confirm the code — ask whether the appliance is billed as preventive (D1510) or orthodontic before treatment, since that decides your coverage.
Frequently asked questions
How much does a space maintainer cost?
A band-and-loop space maintainer for a single lost baby tooth costs about $200-$500. A bilateral lingual arch that holds space across the lower jaw runs roughly $400-$800. Both are far cheaper than the orthodontics needed later if a baby molar is lost early and the adult tooth becomes blocked.
How much does a child's palatal expander cost?
A rapid palatal expander (RPE) for a child typically costs $1,000-$3,000, depending on the design and region. It is most effective between ages 7 and 10, while the mid-palatal suture is still soft. After about age 12 the suture fuses and expansion usually requires miniscrews or surgery, which costs far more.
Does insurance cover space maintainers and expanders?
Most dental plans cover space maintainers well — often 100% for children under 14 under code D1510 — because they are preventive. Palatal expanders are usually classified as orthodontics, so they fall under the limited ortho rider (about 30%-50%, lifetime cap) rather than full preventive coverage. Always confirm the code before treatment.
Why does my child need a space maintainer?
When a baby molar is lost early to decay or trauma, the neighboring teeth drift into the gap and block the adult tooth from erupting. A space maintainer holds that spot until the permanent tooth comes in. Skipping it can lead to an impacted tooth needing surgical exposure plus braces — easily $7,000+ versus a few hundred dollars now.
Does a space maintainer hurt to place?
No. Placement takes two short visits — one for impressions, one to cement the appliance — and needs no injections. Children usually describe it as feeling like food stuck between teeth for a day or two. It is one of the least invasive procedures in pediatric dentistry.
How long does a child wear a palatal expander?
Active turning lasts about 2-4 weeks, but the expander stays in for several more months so new bone can fill and stabilize the widened suture before it is removed. A temporary gap between the upper front teeth during this time is the expected, healthy sign that the jaw is widening.
What happens if my child loses a front baby tooth?
Usually nothing that needs a spacer. Front baby teeth (incisors) don't drift the way back molars do, so a space maintainer is rarely required for them. Space maintainers matter most for primary molars, where drifting reliably blocks the permanent tooth.
How do you clean around a space maintainer?
Brush gently around the band and avoid sticky candy (gummies, taffy, caramel) that can pull the appliance loose. If it ever feels loose, call the dentist promptly — a partly detached spacer can press on the gum and cause irritation or infection. Routine soft-brush cleaning is otherwise enough.
