What are the normal spaces between the primary teeth called?

The normal spaces between the primary teeth are referred to as primate spaces. These are essential anatomical features that typically occur in the primary dentition to accommodate the larger permanent teeth that will erupt later. Primate spaces allow for proper alignment and spacing of the erupting permanent teeth, facilitating a smooth transition from primary to permanent dentition.

These spaces primarily occur in the maxillary arch between the canine and lateral incisor, as well as in the mandibular arch between the canine and first molar. Their presence is a natural aspect of dental development as they help prevent crowding of the permanent teeth, contributing to overall oral health and proper occlusion.

The other terms listed do not accurately describe these specific spaces in primary teeth. For instance, interdental spaces refer more broadly to gaps between any two adjacent teeth, while terms like primary gaps or transitional space do not specifically relate to the spaces noted within the primary dentition. Hence, primate spaces is the most precise and relevant term for this context.
