Space Maintainers for Children: Preserving Smiles and Dental Development


Space maintainers play a crucial role in pediatric dentistry by preserving the proper spacing and alignment of teeth when a primary (baby) tooth is lost prematurely. These dental appliances help ensure that permanent teeth can erupt into their correct positions, preventing orthodontic complications in the future. In this article, we will explore the importance of space maintainers for children, their types, and how they contribute to the healthy development of their smiles.

The Importance of Space Maintainers for Children

When a primary tooth is lost prematurely due to decay, injury, or other reasons, adjacent teeth may start to shift into the empty space. This can cause crowding, misalignment, and improper eruption of permanent teeth. Space maintainers are designed to hold the space left by the missing tooth, allowing the permanent teeth to erupt in their designated positions. They aid in maintaining the natural alignment of teeth, preventing the need for more extensive orthodontic treatment later on.

Types of Space Maintainers

There are two primary types of space maintainers used in pediatric dentistry:

1. Removable Space Maintainers

Removable space maintainers are typically made of acrylic and consist of an artificial tooth or teeth attached to a plastic base. These maintainers can be easily taken out and reinserted by the child or parent for cleaning purposes. Removable space maintainers are commonly used when the missing tooth is in the front of the mouth.

2. Fixed Space Maintainers

Fixed space maintainers are cemented or bonded to the adjacent teeth and are not meant to be removed by the child or parent. They are often made of stainless steel or a combination of metal and plastic. Fixed space maintainers are more durable and appropriate for situations where the missing tooth is in the back of the mouth, where chewing forces are greater.

The Process of Placing Space Maintainers

The placement of space maintainers typically involves the following steps:

  1. Evaluation and Treatment Planning: The dentist will evaluate the child’s oral health and determine the need for a space maintainer. X-rays and dental examinations will help assess the situation and plan the appropriate treatment.
  2. Impressions or Measurements: The dentist will take impressions or measurements of the child’s teeth to create a custom-made space maintainer that fits accurately and comfortably.
  3. Placement of the Space Maintainer: For fixed space maintainers, the dentist will bond the appliance to the adjacent teeth using dental cement or a similar adhesive. Removable space maintainers can be easily inserted and removed by the child or parent following the dentist’s instructions.
  4. Instructions and Care: The dentist will provide instructions on how to care for the space maintainer, including cleaning techniques and any dietary restrictions. Regular check-ups will be scheduled to monitor the progress and ensure the space maintainer remains effective.

Caring for Space Maintainers

Proper care and maintenance of space maintainers are essential to ensure their effectiveness. Here are some tips to follow:

  • Oral Hygiene: Encourage your child to brush their teeth and the space maintainer gently to remove plaque and food particles. Regular flossing is also important to maintain oral hygiene.
  • Dietary Considerations: Advise your child to avoid sticky and hard foods that may damage or dislodge the space maintainer. Follow any dietary restrictions recommended by the dentist.
  • Regular Dental Check-ups: Schedule regular dental check-ups to monitor the condition of the space maintainer and ensure it remains functional. The dentist will assess the progress of dental development and make any necessary adjustments.


Space maintainers are essential appliances in pediatric dentistry, as they help preserve the proper spacing and alignment of teeth when a primary tooth is lost prematurely. By maintaining the space, they facilitate the eruption of permanent teeth in their correct positions, reducing the likelihood of orthodontic complications. If your child loses a baby tooth prematurely, consult with a pediatric dentist to determine if a space maintainer is necessary. Help your child maintain a healthy and properly aligned smile with the aid of space maintainers.
