Space Maintenance
Preventive procedures are done in anticipation of the development of a problem. If a child loses his milk teeth before the time of their natural fall due to decay or accident, then it becomes mandatory to maintain this space of fallen teeth; otherwise, adjacent teeth tend to occupy this space, and a natural tooth that is developing under this space will not be able to erupt in this space. So it will keep lying inside the bone or come out from some other direction. Preventive procedures are done in advance to prevent dental problems that may develop in the future.
