By roughly one to one and a half years of age, this tooth would have been either recently erupted or in the process of erupting.

Its presence in the archaeological record suggests that it was shed or displaced at or shortly after death, entering the sediment of the cave at approximately the same time as the child’s other remains, whatever form those took.

The remainder of the child’s physical existence — if any bones survived the millennia and the particular preservation challenges of the Seward Peninsula — has not been documented.

The scientific record as known is the tooth.
