Of course the creation of teeth allows the setting to be done
in alternate directions, as long as the bend occurs
somewhere within the teeth.

If the seperate teeth didn't exist (e.g. if the gullets between
them were magically filled back in) setting one tooth
would pull on the teeth either side of it.

Therefore tooth setting *MUST* be done at some
sage after tooth creation (effectively tooth shaping)
