Introduction - Types of Space Maintainers
Space maintainers are special devices used in Orthodontics and Pediatric Dentistry to fill the gap left by a prematurely lost baby tooth. This lets permanent teeth erupt in the correct places, preventing tooth development issues. Space maintainers come in two different forms, each with its own set of requirements and circumstances.

Fixed Space Maintainers
Fixed space maintainers are glued or bonded to a child's teeth. These maintainers are custom-made and intended to remain in place until the permanent tooth erupts. They are often recommended for younger children who may lack the discipline to properly use removable alternatives.
Common types of fixed space maintainers are:
- Band and loop: Used when one tooth is missing, and consists of a metal band wrapped around a nearby tooth and a loop extending into the space to keep it open.
- Lingual holding arch: Ideal for children who are missing numerous teeth, or when some space loss has already happened. Used in the lower arch to keep the back teeth from sliding forward. Tends to be more stable than a band and loop or distal shoe.
- Nance: Ideal for children who are missing numerous teeth or when some space loss has already occurred. Used in the upper arch to prevent the back teeth from sliding forward. Also tends to be more stable than a band and loop or distal shoe.
- Distal shoe: This type is commonly used when a child's molar is lost prematurely; it extends below the gum line to make room for the upcoming permanent molar.
Removable Space Maintainers
Removable space maintainers mimic orthodontic retainers and can be removed for cleaning or mealtimes. These are normally advised for older children who are capable of handling the responsibility.
Removable maintainers can include:
- Acrylic hawley retainers/plates with prosthetic teeth or wires used to hold the space open.
- Designs that include functionality, such as fixing small alignment errors.
While removable solutions are less invasive, they require a high level of compliance and care to produce results.
Materials Used
Space maintainers are made of durable and safe materials to provide long-term use with minimal discomfort. Common materials include:
- Stainless Steel: Stainless steel is commonly used for stationary maintainers due to its strength and resistance to corrosion.
- Acrylic: This lightweight and adaptable material is commonly used in removable maintainers to ensure a snug fit.
- Resin/Cement: Used to secure fixed space maintainers in place.
Why Some Kids Need Them
Maintaining the right tooth alignment and spacing is essential for children's oral health. Space maintainers are important for avoiding future orthodontic issues when baby teeth are lost too soon.
Premature Tooth Loss
When a baby tooth falls out sooner than anticipated, the neighboring teeth may move into the gap. This movement may obstruct the permanent tooth's pathways, resulting in overcrowding and problems with alignment. By keeping the gap open, space maintainers enable the permanent tooth to erupt in the correct location.
There are several causes of premature tooth loss, including:
- Decay of the teeth.
- Harm or trauma.
- Lack of teeth from birth.
Orthodontic Implications
Losing a baby tooth can cause the dental arch's natural alignment to be disrupted if nothing is done. Later on, more extensive orthodontic treatment, like braces or aligners with permanent tooth extractions, may be necessary for full correction. A proactive solution is offered by space maintainers, which assist in:
- Reducing further orthodontic issues in the future.
- Preserving the dental arch's equilibrium and shape.
- Lessen the need for more intrusive adolescent treatments.
Installation Process
The process of installing a space maintainer involves several steps, starting with careful planning and assessment. This guarantees that the appliance is customized to meet the child's specific oral needs and continues to work well as they grow.
Evaluation and Planning
Your Orthodontist does a comprehensive assessment prior to putting in a space maintainer. This includes:
- Reviewing dental history and X-rays to assess the position and development of permanent teeth.
- Identifying the type of space maintainer suitable for the child’s specific need
In order to make sure the parents and children understand the significance of the device and how to take care of it, your Orthodontist will explain the procedure.
Fitting and Adjustment
After selecting the appropriate spacer, the Orthodontist either shapes it to the child's mouth, or a custom space maintainer is created by a lab from a 3D digital intraoral scan. The actions consist of:
- Taking impressions or digital scans (more ideal) to create a precise model of the teeth.
- Fabricating the maintainer in a dental lab.
- Cementing or placing the device during a follow-up visit.
Over time, modifications may be required to account for the child's development and growth.
Maintenance and Care
For space maintainers to be functional and for the child's general dental health, proper care and upkeep are essential. To maintain the device's quality, parents and kids need to adhere to certain rules.
Cleaning Guidelines
For space maintainers to remain functional and long-lasting, proper cleanliness is necessary. Children and parents should:
- Brush and floss carefully around the device to prevent plaque buildup.
- Use fluoride toothpaste to strengthen surrounding teeth.
- Rinse with a child-friendly mouthwash for added protection.
Cleaning removable maintainers should be done by brushing them every day and soaking them in a denture cleaner.
Regular Dental Check-Ups
Frequent checkups with the Dentist or Orthodontist help ensure that the space maintainer is operating as planned. These examinations enable the expert to:
- Monitor the growth of permanent teeth.
- Make adjustments if needed.
- Address any issues, such as loosening or damage to the device.

Potential Issues and Management
Despite their effectiveness, space maintainers can cause problems when used improperly. Knowing when to seek expert assistance and being aware of potential issues can have a big impact.
Common Complications
Despite being predominantly safe, space maintainers may:
- Loosen or dislodge over time.
- Cause irritation or soreness of the surrounding gum tissue.
- Cause difficulty in maintaining good oral hygiene.
Promptly addressing these concerns can prevent more serious issues.
When to Contact an Orthodontist
Parents should contact the Dentist or Orthodontist for their child if they notice:
- Persistent pain or discomfort.
- The device is loosened or damaged.
- Signs of infection, such as swelling or redness around the space maintainer
Prompt action helps guarantee the device's continued comfort and effectiveness.

Conclusion: The Role of Space Maintainers in Dental Health
After premature baby tooth loss, space maintainers are important for maintaining the alignment and overall health of a child's teeth. They reduce the need for expensive orthodontic treatments later in life by keeping the gap open, allowing permanent teeth to grow into their proper places. Space maintainers provide a straightforward, yet effective, long-term oral health solution when used correctly, maintained, and examined by a dentist on a regular basis.
