part of develops from adjacent to uncondensed odontogenic mesenchyme we follow ZFA in introducing an additional distinction between the dental papilla and the (uncondensed) mesenchyme. Note that in some species such as zebrafish teeth are not part of the mouth, and sharks have dermal denticles which share similar developmental origins with teeth. For now we assume a NC origin for all and add a taxon restriction to 1st arch mesenchyme tooth enamel organ mesenchyme derived from head neural crest loose mesenchyme tissue tooth bud
