Space Maintainers for Lost Teeth
If your child loses a baby tooth very early such as in an accident or injury, a space maintainer may be used to give support to other teeth to help protect their development.
Baby Teeth are Critical For Development
Sometimes injury or disease can cause a baby tooth to be lost prematurely. When that happens, the permanent teeth that are coming in can actually drift into the space that was reserved for another tooth. This can cause teeth to erupt out of position or to be blocked entirely, which may result in crowded or crooked teeth.
Fortunately, if your child loses a tooth prematurely, there’s a dental appliance we can use to hold the space open for the permanent tooth that is meant to fill it. The device, called a “space maintainer,” is made of metal and/or plastic and can be fixed (cemented) or removable, but either way, their purpose is the same: to help your child develop the best bite possible and hopefully avoid the need for braces later on.
Fixed Space Maintainers
Fixed appliances are cemented onto adjacent teeth. They are made in many different designs: One consists of a band that goes around a tooth and then a wire loop that extends out from the band to hold the space; another features a loop attached to a stainless steel crown, which goes over a nearby tooth. In either case, the loop extends just to the point where it touches the next tooth. Fixed space maintainers are often preferred with younger children because they are less easy to fidget with, break, or misplace than appliances that can be removed.
Removable Space Maintainers
Removable appliances look like the type of retainer that is worn at the end of orthodontic treatment. It can have a false tooth on it, which is particularly useful when the lost tooth was visible in the mouth. Older children can usually handle the responsibility of wearing this appliance and caring for it properly.
Whether fixed or removable, your child’s space maintainer will be custom-made after we take impressions of his or her mouth. A child will wear a space maintainer until x-rays reveal that the tooth underneath is ready to erupt naturally. It is very important that anyone wearing a space maintainer keep up good oral hygiene at home and come in for regular professional dental cleanings.
Space maintainers are also useful when one or more permanent teeth are congenitally missing — in other words, they have never existed at all. In cases like this, which are not uncommon, permanent dental implant teeth are often recommended for adolescents or adults to replace a tooth they weren’t born with. But timing is very important with dental implants — they can’t be placed in a growing child. Therefore, we may use a space maintainer with a false tooth on it until jaw growth is complete and an implant can be appropriately placed. It’s a simple, non-invasive way we can avoid a malocclusion (bad bite) with some timely intervention.
