Space Maintainers

Used when a baby tooth is lost prematurely, a space maintainer helps hold open the gap until the permanent tooth is ready to come in naturally. This appliance from our Bethesda, MD, pediatric dentist prevents nearby teeth from shifting into the empty space, which can cause crowding or alignment issues later. By preserving proper spacing, space maintainers support smoother transitions as a child’s adult teeth emerge and reduce the need for more extensive treatment later on.

How Long Is a Space Maintainer Worn?

The length of time a child needs to wear a pediatric space maintainer depends on their individual oral development and the timing of the tooth loss. Space maintainers are most often used when a baby tooth is lost earlier than expected due to injury, decay, or extraction. In these cases, the appliance helps keep the open space available until the adult tooth is ready to erupt.

A fixed space maintainer can stay in place for some time if needed. Because children may lose teeth weeks, months, or even years ahead of the normal schedule, the timeline is different for every patient. Our local pediatric dentist will monitor your child’s growth and tooth development during regular visits to determine how long the appliance is needed.

As your child grows, the space maintainer continues to do its job quietly in the background, helping prevent nearby teeth from shifting into the open space. Once the permanent tooth starts to emerge, the appliance can be removed at the appropriate time.

Are There Different Types of Space Maintainers?

There are two main types of space maintainers, and the right option depends on how many teeth were lost and where the gaps are located in your child’s mouth.

• Fixed unilateral space maintainers are used when a single baby tooth is lost on one side of the mouth. This type of appliance preserves space on that side only and is commonly recommended when the surrounding teeth are at risk of shifting.
• Fixed bilateral space maintainers are used when multiple baby teeth are lost on both sides of the mouth. These appliances manage spacing across a wider area and help maintain balance as the jaw continues to grow and develop.

Both types are custom made to fit your child’s mouth and are designed to stay securely in place while being comfortable for everyday activities.
