Space Maintainers

Space maintainers play a crucial role in pediatric dentistry by addressing the aftermath of prematurely lost primary teeth, ensuring the proper alignment and spacing of the developing permanent dentition. These dental appliances serve as proactive measures to preserve the integrity of the dental arch and prevent potential orthodontic complications that may arise from tooth loss during childhood.

Primarily designed for children who have lost one or more primary teeth prematurely due to factors such as trauma or decay, space maintainers serve as placeholders, occupying the vacant space left behind by the missing tooth. By maintaining the natural gap between adjacent teeth, space maintainers prevent the surrounding teeth from drifting or shifting into the open space, thereby preserving the ideal alignment and spacing of the dentition.

The importance of space maintainers lies in their ability to mitigate the risk of orthodontic problems that may emerge as a consequence of tooth loss during childhood. Without adequate intervention, the absence of a primary tooth can disrupt the natural alignment of the remaining teeth, leading to issues such as crowding, misalignment, or malocclusion. By installing a space maintainer, dental professionals can effectively guide the eruption and alignment of the permanent teeth, promoting optimal occlusion and oral health in the long term.

At Downtown Sleep Dentistry & Oral Surgery, we specialize in providing fixed space maintainers, which are custom-crafted dental appliances designed to remain in place for an extended period to preserve the integrity of the dental arch. Made of durable materials such as metal, fixed space maintainers offer stability and reliability in maintaining the desired spacing between teeth. These appliances are meticulously fabricated to fit the unique contours of the patient’s dental anatomy, ensuring optimal comfort and functionality.

Fixed space maintainers are typically cemented onto the adjacent teeth, anchoring them securely in position to prevent any movement or displacement. This ensures that the space maintainer remains effective in its role of preserving the space and guiding the eruption of the permanent teeth. The placement of fixed space maintainers is performed under the guidance of a skilled dentist, who will assess the child’s individual needs and recommend the most suitable type of space maintainer based on various factors such as the location of the missing tooth, the child’s age, and dental development.

When considering the installation of a space maintainer for a child, it is essential to have a consultation with a qualified dental professional who can provide personalized guidance and treatment recommendations tailored to the child’s specific needs. 

 During the initial consultation, the dentist will conduct a comprehensive evaluation of the child’s dental health and discuss the benefits of space maintainers as part of a comprehensive treatment plan. 


In addition to their role in preventing orthodontic issues, space maintainers offer numerous advantages for pediatric patients, including:

  1. Preservation of dental alignment: By maintaining the natural spacing between teeth, space maintainers help preserve the proper alignment of the dentition, reducing the likelihood of crowding or misalignment.
  1. Facilitation of proper eruption: Space maintainers guide the eruption of permanent teeth into their correct positions, promoting optimal occlusion and oral function.
  1. Prevention of dental complications: By preventing adjacent teeth from drifting into the open space, space maintainers reduce the risk of orthodontic problems and potential dental issues that may arise from tooth loss.
  1. Maintenance of oral health: By preserving the integrity of the dental arch and promoting proper alignment, space maintainers contribute to overall oral health and well-being, facilitating effective chewing, speech, and oral hygiene practices.

Space maintainers represent an invaluable tool in pediatric dentistry for preserving the integrity of the dental arch and guiding the eruption of permanent teeth following premature tooth loss. Through the use of fixed space maintainers, dental professionals can effectively prevent orthodontic complications and promote optimal dental development in children. If your child has experienced premature tooth loss, we encourage you to schedule a consultation with our experienced dental team to discuss the benefits of space maintainers and explore treatment options tailored to your child’s unique needs. Together, we can ensure the long-term health and vitality of your child’s smile.

Getting my wisdom teeth removed as an adult was daunting due to all the scary tales I'd heard. I found myself calling the office repeatedly for reassurance, and I must say, the staff at Downtown Sleep Dentistry and Oral Surgery truly transformed my experience. Their support and care made it incredibly calming. I can't recommend them enough. Dr. Cuddy was not just informative but also incredibly compassionate. Dr. Blackmore has been by my side throughout my entire recovery, checking in with me daily—it's been nothing short of amazing. The nurses were kind and really helped ease my nerves before the procedure. From the administrative start to the final step, it was simply the best. I'm planning to return to them for my TMJ issues in the future. Thank you to the ENTIRE team at Downtown Sleep Dentistry and Oral Surgery!
