Space Maintainers: Restoring Proper Tooth Alignment in Children

The Importance of Proper Tooth Alignment in Children

Proper tooth alignment plays a crucial role in children's oral health and overall well-being. It affects their ability to chew, speak clearly, and maintain good oral hygiene. Additionally, proper tooth alignment contributes to a confident smile, promoting positive self-esteem and social interactions. When teeth are lost prematurely or erupt abnormally, it can lead to misalignment and other dental issues. Space maintainers are dental devices designed to preserve the space for permanent teeth, ensuring proper alignment and bite development.

Understanding Space Maintainers

Space maintainers are custom-made dental appliances used to hold the space created by prematurely lost primary (baby) teeth. They are specifically designed to prevent adjacent teeth from shifting into the empty space and maintain sufficient room for permanent teeth to erupt properly.

Types of Space Maintainers

Fixed Space Maintainers

Fixed space maintainers are devices that are cemented or bonded to the adjacent teeth. They consist of a metal or plastic wire loop that spans the gap left by the missing tooth, holding the space open. These maintainers are typically recommended for cases where multiple teeth are missing or the space needs to be preserved for an extended period. Unlike other types of orthodontic devices, a permanent fixture in the form of a stainless steel space maintainer is known to be both secure and reliable.

Removable Space Maintainers

Removable space maintainers are designed to be taken out of the mouth for cleaning or adjustment. They usually consist of an acrylic base that rests on the gums and artificial teeth or wire extensions to fill the gap. Removable space maintainers are recommended when only one or a few teeth are missing or when there is a need for periodic adjustments. They provide flexibility and ease of cleaning, but they require consistent cooperation from the child in wearing and caring for the appliance.

When are Space Maintainers Needed?

Early Loss of Primary Teeth

Space maintainers may be necessary if a child loses a primary tooth prematurely due to decay, trauma, or other dental issues. Premature tooth loss can disrupt the natural spacing and alignment of the teeth, leading to complications as permanent teeth begin to erupt. Space maintainers help preserve the empty space, preventing neighboring teeth from drifting into it and ensuring there is enough room for the permanent tooth to emerge properly.

Impacted or Delayed Eruption of Permanent Teeth

In some cases, permanent teeth may be delayed or fail to erupt properly due to factors such as genetics, overcrowding, or impaction. Space maintainers can help create the necessary space and guide the eruption of these teeth into their proper positions. By maintaining the space, space maintainers contribute to a healthier and more aligned dentition.

Benefits of Space Maintainers

Preventing Shifting and Misalignment

When primary teeth are lost prematurely without intervention, neighboring teeth may drift or tilt into the vacant space, leading to crowding and misalignment. Space maintainers help maintain the proper alignment of teeth, preventing shifting and reducing the need for more extensive orthodontic treatment in the future.

Facilitating Proper Bite Development

Proper bite development is essential for efficient chewing and proper jaw alignment. Space maintainers help maintain the natural spacing of teeth, allowing the jaws to develop harmoniously and reducing the likelihood of bite problems, such as crossbites or overbites.

The Process of Getting Space Maintainers

Consultation and Evaluation

Having an initial consultation with a pediatric dentist or orthodontist is needed to begin getting space maintainers. After examining a child's oral health, X-rays of their mouth will be taken and evaluated by a specialist. Depending on their dental development, they will determine whether or not space maintainers are necessary for them.

Customization and Placement

Parents who opt to have a space maintainer for their child often turn to the dentist to create and fit the device. An impression of the youngster's teeth is taken which allows the dental professional to design something that fits snugly. This is essential for making sure it stays comfortable and works effectively. The space maintainer will be designed to match the child's mouth and provide the necessary support and retention. During a subsequent appointment, the space maintainer will be placed and adjusted to ensure a comfortable fit.

Monitoring and Maintenance

In order to ensure the success of the space maintainer, subsequent visits with the dentist should be scheduled. During such meetings, adjustments can be made and guidance will be supplied on how to take care of it correctly.

Caring for Space Maintainers

Oral Hygiene Practices

Maintaining good oral hygiene is essential when wearing space maintainers. Children should brush their teeth thoroughly, including the space maintainer, at least twice a day. Flossing should be done carefully, ensuring the floss reaches under the space maintainer to remove any trapped food particles.

Regular Dental Check-ups

It's important for the dental health of children to be monitored regularly in order to track the development of space maintainers, assess oral hygiene and address any potential issues. The dentist can decide how often a child should have their check-ups according to their individual requirements.

Handling Repairs or Adjustments

If the space maintainer becomes loose, damaged, or uncomfortable, it is important to contact the dentist promptly for repair or adjustment. Attempting to fix or adjust the appliance at home may lead to further complications or ineffective treatment.


Space maintainers play a significant role in restoring proper tooth alignment in children by preserving space and preventing the shifting of teeth after premature tooth loss. Having healthy teeth is important for a wonderful smile, and space maintainers can play a significant role in this. Working hand-in-hand with an orthodontist or pediatric dentist, these devices keep the necessary spacing and alignment to reduce the chances of requiring extensive treatment down the line. Not only does this lead to strong dentition but also greater oral health and well-being overall.
