When there is a case of hypodontia of the permanent premolar teeth, the primary molar teeth would often remain in the mouth beyond the time they are meant to be lost. [76] Therefore, with a presence of healthy primary teeth in the absence of a permanent successor, retaining the primary teeth can be a feasible management of hypodontia.
Tooth loss is a process in which one or more teeth come loose and fall out. Tooth loss is normal for deciduous teeth (baby teeth), when they are replaced by a person's adult teeth.

In these cases, teeth may lose their weakened enamel shortly after eruption and are highly susceptible to dental caries.
