When a baby tooth is lost too early, the neighbouring teeth can drift into the gap, though not in every child. That can leave less room for the adult tooth waiting underneath. A space maintainer is an appliance used to manage or reduce that risk.
In this article we explain what a space maintainer is, the different types and when one might be considered. Only a dentist can decide whether your child needs one, after examining them.
What is a space maintainer?
A space maintainer is a small appliance made to hold the gap left by a baby tooth that was lost early. It stops the neighbouring teeth drifting into the space and keeps room for the adult tooth developing below.
Baby teeth matter not only for chewing and speech but because they guide the adult teeth into place. That’s why the gap is assessed after an early loss.
What happens if a baby tooth is lost early?
When a baby tooth is lost early through decay, infection or injury, you may see:
- Neighbouring teeth drifting into the gap
- Less room for the adult tooth
- The adult tooth coming in at an angle or crowded
- Changes in how the upper and lower teeth meet
Not all of this happens in every child. The risk depends on which tooth was lost, the child’s age and how close the adult tooth is to coming through. For some children, regular check-ups may be recommended instead of a space maintainer.
When is a space maintainer needed?
The dentist usually considers:
- Which baby tooth was lost, and when?
- How the adult tooth is developing and when it’s due
- The width of the gap and the position of the neighbouring teeth
- X-ray findings, if needed
Without this assessment, it isn’t right to say “it’s needed” or “it isn’t”.
Types of space maintainers
There are two main groups. The dentist decides which suits your child based on their age, how many teeth are missing and where.
Fixed space maintainers
These are bonded in place by the dentist and can’t be removed by the child. Common types:
- Band and loop: attached to a neighbouring tooth to hold the space when a single baby molar is lost.
- Lingual arch: used in the lower jaw to hold space for more than one tooth.
- Nance appliance: used in the upper jaw in selected cases to hold the back teeth in position.
- Distal shoe: a special type used in selected cases where the second baby molar is lost before the first adult molar has come through.
Removable space maintainers
Made from impressions of the child’s mouth, these can be taken in and out. They’re mostly used when more than one tooth is missing. Because they need to be worn consistently, the child’s and family’s commitment matters.
At what age is a space maintainer fitted?
There’s no fixed age. What matters is how old the child was when the tooth was lost and how long until the adult tooth comes through.
For example, if a child loses a baby molar at 5, the adult tooth may not appear for years, so holding the space may matter more. If the same tooth is lost when the adult tooth is about to come through, a different approach is usually taken.
How is a space maintainer fitted?
- Examination: we look at the lost tooth, the gap and the neighbouring teeth.
- Imaging: if needed, an X-ray shows where the adult tooth is.
- Choosing the appliance: fixed or removable.
- Fitting: impressions or a digital record are taken, the appliance is made and fitted.
- Follow-up: we explain how to care for it and schedule check-ups.
While it’s being fitted or in the first few days, your child may feel slight pressure or that something unfamiliar is in their mouth. If discomfort continues, the gum gets sore or the appliance breaks, contact the dentist.
How long is it worn?
It varies. The aim is to keep it in until the adult tooth comes through. The dentist watches for this at check-ups and decides when to remove it.
Caring for a space maintainer
- Brush twice a day and clean carefully around the appliance.
- Follow the dentist’s advice on sticky and hard foods.
- Removable appliances should be worn and cleaned exactly as the dentist explains.
- If it loosens, breaks or causes a sore, see the dentist straight away.
- Don’t miss check-ups.
What if a space maintainer isn’t fitted?
In a child who does need one, the gap can close over time and the adult tooth may come in crowded, which could mean orthodontic treatment later. But the risk isn’t the same for every lost tooth. Having your child examined after an early loss is what makes the right decision possible.
Frequently asked questions
Is a space maintainer always needed after a baby tooth is pulled?
No. The dentist decides based on your child’s age, the tooth lost and how the adult tooth is developing.
Will it stop the adult tooth coming through?
When it’s chosen and monitored properly, its whole purpose is to leave room for the adult tooth. When the tooth starts to come through, the appliance may need to be changed or removed.
Is it the same as braces?
No. A space maintainer keeps an existing gap open; braces move teeth into new positions. For more, see our orthodontic assessment page.
Can my child eat normally with one?
A fixed one stays in, so follow the dentist’s advice on food. For removable ones, the dentist will tell you whether to wear it while eating.
Does a lost front baby tooth need one?
Not always. Your child’s age, why the tooth was lost and how the teeth are developing are all taken into account.
How much does a space maintainer cost?
It depends on the type of appliance, how many teeth are missing and what’s involved. We’ll let you know after the examination.
