Space Mainainers
Why a Space Maintainer Is Often Needed
Baby teeth aren’t just temporary chewing tools. Each one acts as a natural “guide” that holds the space for the permanent tooth growing underneath. When a baby tooth is lost prematurely (often months or years before its natural shedding time), the surrounding teeth start drifting into the empty space — sometimes within weeks.
- That drift causes:
- Loss of the space the permanent tooth needs to come through
- Crowding of the permanent teeth
- Permanent teeth that erupt in the wrong position or get trapped (impacted)
- Orthodontic treatment later that could have been entirely avoided
- A simple space maintainer fitted promptly after early tooth loss prevents all of the above — at a fraction of the cost and complexity of later orthodontics
When We Recommend a Space Maintainer
- After early loss of a baby molar (the most common reason)
- After trauma resulting in baby tooth loss
- After extraction of a non-restorable baby tooth
- In children whose permanent tooth eruption is delayed
- In children whose permanent tooth eruption is delayed
- Not every early tooth loss needs a space maintainer — sometimes the permanent tooth is close to erupting and would come through before drift becomes a problem. A small X-ray tells us exactly what's needed.
Why Treating Baby Teeth Matters
Assessment:
After a baby tooth has been lost (or before its planned extraction), we examine the area and take a small X-ray to check the development of the permanent tooth underneath. This tells us how long the space needs to be maintained — and which type of appliance is most appropriate.
Impression or digital scan:
A quick, comfortable impression of the area (or digital scan). No drilling, no anaesthesia, no discomfort.
Laboratory fabrication:
The appliance is custom-made in a paediatric dental laboratory. Typical turnaround: 7–10 days.
Fitting:
At the fitting visit, the band is sized and gently cemented (for fixed appliances) or fitted comfortably (for removable). Painless, takes about 20–30 minutes.
Monitoring:
We check the appliance at every 6-monthly check-up to make sure it's still well-fitted, intact and doing its job.
Removal:
When the permanent tooth begins to erupt, the space maintainer is removed in a quick, painless appointment
Caring for a Space Maintainer
- Brush carefully around the appliance, paying special attention to where the band meets the tooth
- Avoid hard or sticky foods that could dislodge it (toffees, chewing gum, ice, hard sweets)
- Don't push or pull at the wire with the tongue (children can be tempted to fiddle)
- Come in immediately if the appliance feels loose or becomes uncomfortable
- Continue routine 6-monthly check-ups
Types of Space Maintainers
Band-and-Loop (Fixed) — Most Common
A small stainless-steel band fits around a neighbouring tooth, with a smooth wire loop that holds the space open. Comfortable, virtually invisible, and impossible for the child to lose. Used for single-tooth space loss — typically the most common situation.
- Best for:
- Single baby molar lost too early
- Cooperative or less-cooperative children alike (it's not removable)
- Long-term placement until the permanent tooth erupts
Lingual Arch (Fixed)
A thin wire that runs along the inside (tongue side) of the lower teeth, anchored to bands on the back molars. Used when multiple baby teeth have been lost in the lower jaw, or when both sides need protection at once.
Nance Appliance (Fixed, Upper Jaw)
Similar to a lingual arch but for the upper jaw, with a small acrylic pad that rests against the roof of the mouth. Used when multiple upper baby teeth have been lost.
Distal Shoe (Fixed)
A specialised appliance used when a baby second molar is lost before the permanent 6-year molar has erupted. The appliance has a small extension that guides the unerupted permanent molar into the right position as it comes through. Particularly important — without it, the 6-year molar often erupts in the wrong place.
Removable Space Maintainer)
An acrylic plate similar to a small retainer with artificial teeth or wire loops. Used in selected cases —particularly when multiple teeth are missing or when aesthetic concerns matter (e.g. lost front teeth). Depends on the child wearing it consistently.
- Best for:
- Older, cooperative children
- Cases where appearance matters (lost front teeth)
- Situations where a fixed appliance isn't suitable
How Long Will It Stay In?
That depends entirely on when the permanent tooth is ready to erupt. Sometimes a space maintainer is in place for just a few months; sometimes for several years. We monitor with periodic X-rays so we know exactly when to remove it — usually just as the permanent tooth is about to come through.
Everything You Need to Know
Frequently Asked Questions (FAQ)
My child lost a baby tooth too early — do they definitely need a space maintainer?
Not always — it depends on which tooth, the child’s age, and how close the permanent tooth is to erupting. A small X-ray tells us exactly what’s needed. If the permanent tooth is coming through within 3–6 months, a space maintainer may not be necessary. If it’s still a year or two away, one is usually a very good idea.
Will the space maintainer hurt or feel uncomfortable?
No. The fitting is painless, and most children adapt within 2–3 days. There may be a brief feeling of “something new” in the mouth, but it doesn’t hurt and doesn’t interfere with eating or speaking.
How long does a space maintainer stay in?
Typically from a few months to a few years — depending on how far the permanent tooth has to develop and erupt. We monitor with periodic X-rays and remove the appliance the moment the permanent tooth is ready to come through.
What if the appliance breaks or comes loose?
Call us immediately. A loose or broken space maintainer needs to be repaired or refitted quickly, because the surrounding teeth can start drifting again within weeks. Re-cementing or repair is usually quick and simple.
Does it affect speech, eating or sports?
Almost never. Most children eat, speak and play sports completely normally with a fixed space maintainer. Soft foods are recommended in the first few days while the child adapts.
Are space maintainers covered by insurance?
Many insurance providers cover space maintainers — they’re considered preventive care that avoids more expensive orthodontic treatment later. We provide detailed receipts and any paper work needed for reimbursement.
Could my child have had a space maintainer and avoided needing braces later?
Sometimes — yes. Many later orthodontic problems can be traced back to early baby tooth loss without proper space management. This is exactly why we recommend space maintainers proactively whenever a baby tooth is lost prematurely.
