What Is a Space Maintainer?
A space maintainer is a small device, usually made of metal or sturdy dental-grade material, that sits in the gap left by a missing baby tooth. It does not move teeth. Its only job is to hold the space open so neighbouring teeth stay where they are. It is made to fit your child's mouth.
Why Early Tooth Loss Matters
Baby teeth normally fall out when the adult tooth underneath is close to coming in. If a baby tooth is lost too soon, the adult tooth may be months or years away. During that time, nearby teeth can tilt or shift into the open space. This can leave too little room for the adult tooth, which may then come in crooked, get stuck under the gum, or push out of line. Keeping the space open helps lower the chance of crowding and bite problems later on.
Common reasons a baby tooth is lost early include:
- Advanced tooth decay that makes an extraction necessary
- A fall, sports hit or other injury to the mouth
- A tooth that has been damaged by infection
- A baby tooth that fell out much earlier than normal
Who May Need a Space Maintainer?
Not every child who loses a baby tooth needs one. Whether it helps depends on which tooth was lost, your child's age, how far along the adult tooth is, and how much space is left. We check the area with an exam and X-rays when needed, then explain what we see. If the adult tooth is about to come in, a space maintainer may not be needed at all.
Types of Space Maintainers
- Fixed (band and loop): A band fits around a neighbouring tooth, with a thin wire loop that sits across the gap. It stays in place and cannot be removed by your child.
- Fixed (crown and loop): Similar to the band and loop, but used when the supporting tooth needs a small crown for protection.
- Lingual arch: A wire that runs along the inside of the lower teeth. It is often used when more than one baby tooth is missing.
- Removable: A plastic appliance, sometimes with a false tooth, that your child can take out. It needs a child who will wear it as directed.
What to Expect at the Visit
- We review your child's health history and examine the area.
- We take digital X-rays if they are needed to see the adult tooth underneath.
- We explain the options in simple terms for you and your child.
- We take a measurement or impression so the appliance fits well.
- We place the appliance, check the fit and show you how to care for it.
Your child may feel pressure when it is first placed, and the mouth can feel a little different for a few days. Most children get used to it quickly.
Before Your Visit
- Tell us when and how the baby tooth was lost, and if there was any injury.
- Let us know about any allergies, medical conditions or medications.
- Bring your insurance information if you have it.
- Explain to your child in a calm, simple way that the dentist is going to help their teeth stay in the right spot.
- Have your child brush and floss before coming in.
After Your Treatment
- Have your child avoid sticky foods such as caramel, gum and chewy candy that can pull on the appliance.
- Avoid hard foods like ice, hard candy and popcorn kernels.
- Teach your child not to push or pull the appliance with their tongue or fingers.
- Brush carefully around the appliance twice a day and clean around the wire or band.
- Keep regular checkups so we can check the fit and watch the adult tooth as it comes in.
- Call us if the appliance feels loose, bent or uncomfortable, or if it comes off.
How Long Does It Stay in Place?
A space maintainer stays in until the adult tooth is ready to come through or until the space is no longer at risk of closing. We monitor progress at regular visits and will let you know when it is time to remove it.
Costs and Payment
Cost depends on the type of appliance and your child's needs. We offer direct billing, accept major insurance and government plans, and have instant financing options. Our fee guide is set at 5% below the ADA Fee Guide. Offers are currently available, so please ask our front desk for details.
Part of Complete Care for Your Child
Regular children's dentistry visits help us catch problems early. Sealants and fluoride help protect teeth from decay, which is a leading cause of early baby tooth loss. If crowding becomes a concern later, we can talk about kids braces and orthodontics.
Frequently Asked Questions
Does my child need a space maintainer every time a baby tooth falls out?
No. Teeth that fall out on their normal schedule usually do not need one. A space maintainer is considered when a baby tooth is lost much earlier than expected and the adult tooth is still far from coming in.
Is a space maintainer painful?
Placing one is usually comfortable. Some children feel pressure or tenderness for the first few days while they get used to it. Soft foods can help during that time.
Can my child eat normally with a space maintainer?
Yes, with a few changes. Sticky and very hard foods should be avoided because they can bend or loosen the appliance.
What if the space maintainer comes loose or falls off?
Call us as soon as you notice and bring the appliance with you. A loose appliance should not be left for long, since the space can start to close.
How do we clean a space maintainer?
Brush it with the rest of the teeth, paying attention to where the wire or band meets the tooth. Floss around nearby teeth as your dentist shows you.
How long will my child need it?
It depends on when the adult tooth is expected. We check regularly and remove the appliance once it is no longer needed.
Will a space maintainer replace braces?
No. It only holds space. Some children still need orthodontic care later, and we can talk about that as they grow.
