Losing baby teeth is an exciting milestone for young kids. But that doesn’t mean we can overlook the important role that these temporary teeth play in overall oral health. They act as placeholders, keeping space reserved as they guide permanent teeth into the correct position. Healthy speech, chewing, and jaw development are all supported by baby teeth.
So, what happens when a baby tooth is lost too early? The surrounding teeth can begin to shift into the newly emptied space. And while it may not seem like a big deal now, it will be when the permanent tooth attempts to erupt.
This is where a space maintainer shines. Let’s take a closer look.
What is a Space Maintainer?
Simply put, a space maintainer is a custom-made dental appliance designed to keep the space open after a baby tooth is lost prematurely. Preserving the correct amount of room helps ensure that the permanent tooth has enough space to erupt in its proper position.
Depending on your child’s needs, there are two options for space maintainers. The first is a fixed oral appliance that attaches to the adjacent teeth until removed by the dentist. This is the one that is most commonly used. However, older, compliant children may prefer a removable oral appliance.
When Does a Child Need a Space Maintainer?
Most children who lose a baby tooth do not need a space maintainer. Several factors are taken into consideration before making the recommendation, such as your child’s age, which tooth was lost, and how soon the permanent tooth should be erupting. The earlier the tooth is lost, the more likely a maintainer will need to be used.
A pediatric dentist may recommend a space maintainer if a baby tooth is lost due to severe decay, knocked out in an accident or with a sports injury, or even extracted due to infection. This is because a permanent tooth will not erupt for several months or years.
How a Space Maintainer is Placed
The process of placing a space maintainer is simple, but the impact is big. There will be an examination of your child’s mouth and, if necessary, X-rays may be taken to evaluate the developing permanent teeth. The oral appliance is then made custom for a comfortable fit.
When it is ready, the space maintainer is placed, and any necessary adjustments are made to ensure the right fit. This new addition may initially feel strange, but most young patients adapt to it within just a few days.
What Happens If a Space Maintainer Isn’t Used?
If a patient needs a space maintainer, but doesn’t move forward with the treatment, adjacent teeth can gradually shift into the space. This can either prevent a permanent tooth from erupting or cause it to do so in an incorrect position. In time, this can look like crowding, bite misalignments, impacted teeth, and more. The need for orthodontic work will likely be elevated.
Addressing early tooth loss appropriately will prevent more complicated dental issues in the future. Take action without delay.

Are space maintainers painful?
No. Most children will adjust quickly after placement and experience little to no discomfort after the first day or two.
How long will my child need to wear a space maintainer?
It depends on when the permanent tooth is ready to erupt. Some children wear one for several months, while others may need it for a few years.
