Space Maintainers

Children may need space maintainers if they lose a tooth early or have a baby (primary) tooth extracted due to dental decay. If either is the case, it is important to know the benefits of using a space maintainer and how it can help support your child's dental health.

A space maintainer is an appliance that is custom-made by your Dr. Donald in acrylic or metal material. It can be either removable or cemented in a child's mouth. Its purpose is to keep the space open to allow the permanent tooth to erupt and come into place.

Baby teeth are important to the developmentdevelopment of the teeth, jaw bones and muscles and help to guide permanent teeth into position when the baby teeth are lost. If a space is not maintained, then teeth can shift into the open space and orthodontic treatment may be required. Not every child who loses a baby tooth early or to dental decay requires a space maintainer; however, a professional consultation with your dentist or orthodontist should be conducted to determine if using a space maintainer is needed.

Types of Space Maintainers

There are two types of space maintainers for children, removable and fixed.

  • Removable – removable space maintainers are similar to orthodontic appliances and are usually made of acrylic. In some cases, an artificial tooth may be used to fill a space that must remain open for the unerupted tooth.
  • Fixed – there are four different kinds of fixed space maintainers: unilateral, crown and loop, distal shoe and lingual.
  • Unilateral, Crown, Loop

    space maintainers are placed on one side of the mouth to hold space open for one tooth. The unilateral space maintainer wraps around the outside of the tooth and is connected to a metal loop that holds the space intact. The crown and loop is an actual crown that covers the tooth and is attached to the loop to ensure there is space for the erupting tooth.

  • Lingual

    space maintainer is usually bilateral in nature and may be cemented to molar teeth and connected by a wire on the inside of the lower front teeth. Usually this is used for more than one missing tooth.

    Sometimes children may be missing teeth due to congenital diseases and may require a partial denture versus a space maintainer. It is important to meet with your dental professional to determine if this is an option.

Wearing the Space Maintainer

Once the space maintainer is made it may take the child a few days to get accustomed to wearing the appliance whether it is removable or fixed. The Dr. Donald will review with you and your child the proper ways to clean the space maintainer thoroughly in order to keep the gum tissue healthy and free of dental plaque. Proper instruction for tooth brushing and flossing should be considered for improved oral hygiene.

If the space maintainer is fixed, it will be important to avoid chewy and sugary foods, and gum or candy, which may loosen or get caught on the appliance. Also, the space maintainer should not be pressed or pushed with the tongue or fingers because it could loosen or bend the appliance.

Dr. Donald will recommend that he sees your child on a regular basis to monitor the progress of treatment with the space maintainer and continue to receive a regular six-month professional cleaning appointment.
