Does Your Child Need a Space Maintainer? A Pediatric Dentist’s Guide to Saving the Spot
This blog has been reviewed by a pediatric dentist.
One of the most common questions we get from parents when a baby tooth is lost prematurely is: “It was going to fall out anyway, right? Why do we need to do anything about it?”
While it’s true that primary teeth are temporary, they have a very permanent job. They act as “placeholders” for the adult teeth waiting under the gums. When a baby tooth goes missing too early, whether due to a playground injury or significant decay, the neighboring teeth don’t just stay put; they tend to tilt, lean, and drift into that empty space.
This is where space maintainers come in. Think of them as small, custom-made, spot-savers for your child’s future adult smile.
What Exactly is a Space Maintainer?
A space maintainer is a specialized orthodontic appliance, usually made of stainless steel. Its sole purpose is to keep the space open until the permanent tooth is ready to erupt.
By holding that space, we ensure the adult tooth has a clear, unobstructed path to come in straight. Without it, the permanent tooth might become impacted, which means trapped under the gum, or erupt in a crooked position, leading to years of expensive orthodontic work down the road.
3 Signs Your Child Might Need a Space Maintainer
Not every lost tooth requires an appliance. If a tooth is lost naturally because the adult tooth is right underneath it, we usually just let nature take its course. However, here is how to know if your child is a candidate for a maintainer:
1. Early Loss Due to Dental Decay
If a primary molar is lost to a cavity before it is scheduled to fall out (usually between ages 10 and 12), a space maintainer may be necessary. The back molars are the teeth most likely to move; if they see an opening, they will drift forward rapidly.
2. Dental Trauma or Impact
Accidents happen, especially during sports or playtime. If a front tooth or a side tooth is knocked out prematurely due to trauma, we need to evaluate the area. While we don’t usually place maintainers for the very front teeth (incisors), we must ensure the surrounding bone and teeth haven’t shifted in a way that blocks the permanent tooth.
3. The “Crowding” Warning
If your child’s mouth is already very crowded, losing even one tooth early can create a domino effect. The existing teeth will move to take up the extra space, leaving no room for the adult tooth to emerge.
Types of Space Maintainers
Depending on where the tooth was lost, we typically recommend one of two styles:
- Fixed Space Maintainers: These are glued to the neighboring teeth. They are the most common for children because they can’t be lost, forgotten, or played with. Common types include the band-and-loop or the lingual arch.
- Removable Space Maintainers: These look a bit like a retainer or a partial denture. They are usually reserved for older, more responsible children or for cases where the missing tooth is in a highly visible area of the mouth.
Life with a Space Maintainer: What to Expect
Fortunately, these appliances are very low-profile. Most children forget they are even wearing them within 24 to 48 hours. However, as a pediatric dental practice, we ask for two things:
- Skip the Sticky Stuff: Avoid taffy, gummy bears, and chewing gum, which can tug on the appliance and loosen the dental cement.
- Keep it Clean: Brushing around the bands is vital to prevent gum irritation and new cavities.
Why Early Intervention Saves You Money
A space maintainer is an investment in prevention. It is significantly more affordable and less invasive to keep a space open now than it is to force a space open later using years of complex braces, oral surgery, or tooth extractions. By “saving the spot,” we are setting the foundation for a straighter, healthier, and more confident adult smile.

FAQS Frequently Asked Questions
Who is a candidate for space maintainers?
Children who have lost a tooth due to trauma, decay, or who have teeth that are already crowded and lose a tooth, are all candidates for space maintainers.
What are space maintainers made of?
Typically, space maintainers are made of stainless steel.
What types of space maintainers are there?
There are generally two types: fixed appliances are cemented in place until removed by a dentist and are generally made of stainless steel, while removable, retainer-like devices rely on patient compliance and are made of acrylic.
What happens to empty gaps without space maintainers?
The biggest risk here is that the teeth around the gap move into the space, causing crowding issues.
How long does it take to apply a space maintainer?
The process generally takes two appointments. During the first, the dentist performs an exam and makes sure a space maintainer is right for the patient. If the adult tooth is about to come in, a space maintainer won’t be necessary. If a space maintainer is needed, the dentist will take an impression of the teeth and gap. The appointment will take about 30 minutes. The impression will be sent off to a lab where they will make the space maintainer in a few weeks. At the next appointment, the dentist will check the fit and then install the space maintainer. The application of the device only takes between 5 and 15 minutes.
Is there a recovery time for space maintainers?
Kids may experience mild soreness and gum discomfort for 2 to 3 days afterwards. Normal activities can resume after 24-48 hours.
Can my child eat anything they want if they have space maintainers?
As with braces, certain foods can affect the dental cement and cause the space maintainers to loosen or even dislodge completely. Foods that should be avoided include sticky, chewy, and hard foods like gum, candy, nuts, ice, etc.
How long will my child need to wear their space maintainer?
Depending on the child, they may need to wear it for a few months to a few years. Once the dentist determines that the permanent tooth is close to erupting using X-rays, the device is removed.
How do you care for space maintainers?
Good oral routines that include brushing twice a day for two minutes and flossing daily with a concentration around the device make a world of difference. Children should avoid pulling on the device or pushing at it with their tongue. Avoid sticky, chewy, or hard foods.
How soon after losing a tooth should a space maintainer be applied?
They should be placed as soon as possible, within a few weeks, or right after the gums heal, so that the teeth around the gap do not move into the space. Immediate placement helps ensure the space is secured before the teeth shift. The back molars, especially, are notorious for this.
What should I do if the device breaks or comes out?
If the appliance is loose or comes out, save it and call the dentist immediately for re-cementation to avoid having it remade.
Will my child need X-rays because of their need for a space maintainer?
Your child will likely need an X-ray to help determine the dimensions of the maintainer needed and to check the status of the permanent tooth below the gums. Then, once the tooth the maintainer held space for is close to erupting, the dentist will order x-rays to see if it’s in position, meaning it’s time to remove the space maintainer.
