Space Maintainers in Las Vegas & Henderson
A small appliance that prevents a large problem. If your child lost a baby tooth ahead of schedule, this is the cheapest orthodontics you will ever pay for.
They are placeholders as much as teeth
Baby teeth do two jobs. The obvious one is chewing. The less obvious one, and arguably the more important, is holding the exact amount of space the permanent tooth underneath will need when it eventually arrives.
Teeth do not sit still. Left with a gap next to them, neighbouring teeth drift and tip into it — steadily, over months. This is exactly the same biological process orthodontics uses deliberately; it simply happens without anyone directing it.
So when a baby molar comes out at six instead of eleven, the permanent tooth beneath has five years of drift to contend with before it emerges. Often it finds no room at all, and either erupts badly out of position or becomes impacted.
A space maintainer holds that gap open. It is a small fixed appliance, it costs a fraction of the braces or the exposure surgery it prevents, and it is one of the genuinely uncontroversial interventions in paediatric orthodontics.
When a space maintainer is recommended
A baby molar lost to decay
The most common reason by a distance. Back baby teeth are the ones that hold the most critical space, and they are also the ones most often lost to decay.
A tooth knocked out
Playground falls, sport, bicycles. If a baby tooth is lost to trauma well ahead of schedule, the space question applies just the same.
A tooth extracted
Where a baby tooth has to be removed for infection or damage, we would rather plan the space maintainer at the same time than address drift six months later.
A permanent tooth that is missing
Where a permanent tooth is congenitally absent, holding the space preserves options — an implant later, or a planned orthodontic closure.
Crowding already developing
Where space is tight to begin with, even a small amount of drift matters more. Maintainers are recommended sooner in these children.
When one is not needed
If the permanent tooth is nearly through anyway, or a front baby tooth is lost close to its natural time, often nothing is required. We will tell you when that is the case.
Timing matters more than most parents realise. Most drift happens in the first six to twelve months after a tooth is lost. A maintainer placed within a few months of the loss prevents the problem entirely; one placed two years later is closing a stable door. If your dentist has just extracted a baby tooth, ask about this now rather than at the next check-up.
Types of space maintainer
Which is used depends on where the gap is, how many teeth are missing, and whether the permanent molars are through yet.
Band and loop
The workhorse. A metal band cemented around the tooth behind the gap, with a wire loop extending across to rest gently against the tooth in front. Simple, small, and used for a single missing baby molar — which covers most cases.
Lingual holding arch
A wire running along the inside of the lower teeth, anchored to bands on both lower molars. Used where teeth are missing on both sides of the lower arch, or where the lower molars need holding as a group.
Transpalatal arch or Nance
The upper equivalents — a wire crossing the palate between the upper molars, sometimes with a small acrylic button resting against it. Holds upper molars in position where space needs preserving on both sides.
Distal shoe
Used in a narrower situation: when a second baby molar is lost before the permanent first molar has erupted. It has a small extension that sits below the gum to guide that molar into the correct position as it comes through.
What to expect once it is fitted
Fitting takes one short appointment
A scan or impression first, then the appliance is cemented at a follow-up visit. No anaesthetic. Most children barely register it.
A few days of feeling odd
Mild awareness rather than pain. Children adapt within days — considerably faster than with an expander or braces.
Avoid the usual foods
Sticky and chewy things pull maintainers loose: caramel, taffy, toffee, chewing gum. Hard sweets and ice can bend the wire. Same list as braces.
Brush around it carefully
Food collects around the band, and decay under a cemented band is the main thing that goes wrong. Brush thoroughly, keep six-month dental cleanings, and use a water flosser if your child will.
Call if it loosens
A loose band is not holding the space, and it traps food underneath. This needs re-cementing promptly rather than at the next scheduled visit.
Removal at the right moment
We monitor and remove it once the permanent tooth is coming through. Left in too long, it can obstruct the very tooth it was protecting — which is why the periodic checks matter.
Space maintainer FAQ
Does my child really need a space maintainer?
It depends on which tooth was lost and how early. A back baby molar lost well ahead of schedule is the clearest case for one. A front baby tooth lost near its natural time often needs nothing at all. We will tell you honestly which situation you are in — and sometimes the answer is that nothing is required.
How soon after losing a tooth should one be fitted?
Within a few months ideally. Most drift happens in the first six to twelve months after a tooth is lost, so a maintainer placed promptly prevents the problem entirely while one placed two years later has far less to preserve. If your dentist has just extracted a baby tooth, raise it now.
Does a space maintainer hurt?
No. Fitting requires no anaesthetic and most children report mild awareness for a few days rather than pain. They adapt considerably faster than with an expander or braces.
How long does it stay in?
Until the permanent tooth underneath is ready to come through, which can be anywhere from months to several years depending on the child’s age and which tooth was lost. We monitor at periodic visits and remove it at the right moment — leaving one in too long can obstruct the tooth it was protecting.
What can my child not eat?
The same list as braces. Sticky and chewy foods pull maintainers loose — caramel, taffy, toffee, chewing gum. Hard sweets and ice can bend the wire. Everything else is fine.
What if it comes loose or falls out?
Call us and keep the appliance if it came out entirely. A loose band is not holding the space and traps food underneath, which risks decay. It needs re-cementing promptly rather than waiting for the next visit.
How much does a space maintainer cost?
Considerably less than the braces or exposure surgery it prevents, which is the comparison that matters. Many dental plans cover space maintainers for children, often well — we can check yours when you call.
Will my child still need braces later?
Possibly — a space maintainer preserves room, it does not straighten anything. What it does is stop a manageable situation becoming a complicated one. Children who have one are often treated more simply later than they would have been without it.

A free evaluation and a 3D scan will tell you whether a maintainer is warranted — and the sooner you ask, the more there is to preserve.
