TOOTH SPACE MAINTENANCE: Keeping the Space Safe for Permanent Teeth

Children as they grow, achieve multiple milestones starting from smile, walk and talk and from the dental perspective , getting the first tooth and the remaining teeth. As a child reaches the 6 years mark the baby tooth start shaking heralding another milestone in the development of the child. Many a times the happy phase of natural tooth loss is overshadowed by dental problems like dental decay, trauma, etc causing the child to lose a tooth before its actual shedding time.


tooth loss cycle

When a milk tooth is lost, it is soon replaced by the permanent teeth that was pushing itself upwards by dissolving the roots of its primary predecessor, as the movement increases, the primary tooth is shed and replaced by a new permanent tooth.


When a tooth has to be removed because of unchecked and untreatable tooth decay or due to any traumatic injury then the cycle takes a different turn. Usually if the permanent successors are in the phase to erupt then it doesn’t create a problem, but if the teeth are lost immaturely i.e. before the permanent successors are ready to erupt then it is a cause for concern.

Though there are many problems that may arise due to early tooth loss like unpleasant smile, tongue thrusting habits etc but the major concern is LOSS OF SPACE for the permanent successors.

If a tooth has been lost prematurely then it is advisable to visit a Pediatric Dentist/ Pedodontist who may evaluate the condition and treat it appropriately using SPACE MAINTAINERS. These are appliances which save the space for the permanent teeth.


REMOVABLE: are acrylic plates with extensions and at times containing artificial teeth. They are like the removable dentures which can be removed and inserted by the patients. In children this is not much preferred as they may not co operate in wearing the appliance.

FIXED: These are made up of stainless steel with each appliance having a wire component and a metal band to be inserted around the teeth. Multiple types are fabricated with different combinations as per the needs of the patients. These are cemented onto the teeth and cannot be removed by the child. Once the teeth start erupting the dentist will remove the appliance.
