The Ultimate Guide to Finding the Right Dental Space Maintainer


When a child loses a baby tooth at a premature age due to decay or other reasons, there is a risk that the permanent teeth could drift out of their proper position and create an uneven space between the teeth. A dental space maintainer is a device used to help prevent this shift by keeping the space available for the permanent tooth to emerge in the correct position. In this article, we will discuss the importance of dental space maintainers, the types available, the installation process, advantages and disadvantages, and other important information related to these devices.

Definition and Importance

A dental space maintainer is a device designed to keep open the space created by a lost baby tooth, in order to allow the permanent tooth to emerge in the proper position. Without a space maintainer, adjacent teeth can move into the gap and create a crowding problem, which can cause the following issues:

  • Difficulty with cleaning teeth, leading to a higher risk of tooth decay and gum disease
  • Difficulty with chewing and biting food
  • Appearance of uneven or crooked teeth

For these reasons, it is essential to maintain space until the permanent teeth grow naturally.

Purpose of the Article

The purpose of this article is to provide a detailed understanding of dental space maintainers. We will discuss the types of maintainers available, the indications and contraindications, the installation process, after-care, cost and insurance coverage, how to choose the right appliance, and potential risks and complications.

The Types of Dental Space Maintainers

There are four main types of space maintainers: Removable, Fixed, Removable-Functional, and Fixed-Functional.

1 Removable Space Maintainers

These are typically made of acrylic or plastic and can be removed for daily cleaning. They are custom-fit to the child’s mouth and held in place using wire clasps.

2 Fixed Space Maintainers

Fixed maintainers are cemented or bonded to the adjacent teeth to prevent them from shifting into the gap. They are typically made of stainless steel wires and bands. Fixed space maintainers are non-removable and require professional removal.

3 Removable-Functional Space Maintainers

These devices also support the proper development of the bite by holding the jaw in its correct position. They are custom-made and can be removed for cleaning.

4 Fixed-Functional Space Maintainers

Fixed-functional devices, such as the Herbst appliance, consist of metal brackets and tubes placed on the upper and lower teeth. Connected by a metal rod, this device helps to promote proper jaw alignment by exercising the muscles in the lower jaw.

Indications and Contraindications

Dental space maintainers can be beneficial for children who have lost baby teeth prematurely and their permanent teeth are not yet ready to emerge. However, there are instances when it is not appropriate to use space maintainers. The following are some indications and contraindications for using dental space maintainers:

Indications for Space Maintainers’ Use

  • Premature loss of baby teeth due to decay or trauma.
  • Space maintainers may be recommended following early extraction procedures, such as orthodontic extractions or teeth removal due to trauma or disease.

Contraindications for Space Maintainers Use

  • Teeth that are already in the proper position and do not require maintenance.
  • Children who are not yet at the appropriate age for the placement of the device.
  • Children who have a high risk of tooth decay, with poor oral hygiene habits.

Installation of the dental space maintainer involves a series of steps, including preparing the mouth, attaching the maintainer, examining dental x-rays, check-ups, and after-care.

1 Preparation of the Mouth

Before installing the space maintainer, the dentist will evaluate the child’s oral health and ensure that their teeth are clean and free of debris. Teeth that require repair will be treated before the maintenance device is placed.

2 Attachment of the Space Maintainer

The dentist will then cement or bond the space maintainer into place. The type of device used will dictate which installation method is chosen.

3 Examination of the Dental X-Rays

Before and after the space maintainer is installed, dental X-rays will be taken to assess the progress of space maintenance and provide guidance on when space maintenance is no longer needed.

4 Check-Up and After-Care

After installation, it is important to follow after-care measures to ensure that the device remains in good condition. The dentist will schedule regular follow-up appointments to monitor progress, make necessary adjustments, and ensure the device is functioning correctly.
