SPACE MAINTAINERS

Space maintainers are used to help maintain space when teeth have been lost prematurely or when there is crowding. The baby upper and lower 2nd molars (dentally known as the "E's") are actually larger than the permanent premolars that will take their place after the large baby molars fall out. The extra space around the premolars is called E space.

Typically the E space is taken up by the back permanent teeth moving forward to take up the space. When there is crowding of the front teeth, the space maintainer is used to allow the front teeth to move back into the E space instead of the back teeth moving forward
