    Shaum says "Teeth are modified epidermal and mesodermal structures...."

    But in destroyer, it says teeth arose from ectoderm only.

    any inputs?

    i think it's safer to go with ectoderm for teeth.
    i am not sure if one of them is right or wrong, since most question is going to ask you which comes from which (instead of which comes from 2 of these), and usually integuments (such as nails and etc.) are always associated with ectoderm, it's prob safer to pick ectoderm in that case.

    Teeth arise from ectoderm and ectomesenchyme (think neural crest cells).

    cliffs says that teeth come from the ectoderm. If cliffs and destroyer are in agreement i think its safe to go with that.

    Tooth enamel comes from ectoderm, but dentin comes from mesoderm.
