Premature loss of a first primary molar can occur due to a multitude of reasons, including caries and infection. When this occurs and restoration of the affected primary tooth is not possible, the AAPD recognizes space maintenance as a “Best Practice” to prevent loss of arch length, width, and perimeter after extraction. However, reports suggest that with proper intercuspation of first permanent molars, space loss from premature loss of a first primary molar is minimal and space maintainers in that area may not be needed. This case report details an 8-year-old female who had significant space loss between the mandibular primary canine and mandibular second primary molar after removal of her band-and-loop space maintainer post-eruption of tooth #19. Patient’s medical history is non-contributory, and she has no known allergies. This report reviews the pertinent literature regarding space management in the mixed dentition and outlines factors to be considered in making clinical decisions regarding such management.
