From Biology-Online Dictionary | Biology-Online Dictionary

The set of teeth consisting of a mixture of primary teeth and secondary teeth.


In humans there are two dentitions, the primary and secondary. The primary teeth (which started to erupt around six months of age) will eventually be shed and replaced by secondary teeth. This shedding and replacement of primary teeth by the secondary teeth start at around six to twelve years of age. The period in which a person has a mixture of primary and secondary teeth is called mixed dentition period.

Compare: primary dentition, secondary dentition
