If moths can "engineer" this that how come man does not grow his own teeth back like sharks, I hate going to the Dentist!.
Firstly, the moths didnt engineer anything, the environment (or even the birds eating them) caused the colour change, over a number of generations, the high reproductive rate of moths mean they produce many offspring, thus the effects are more rapid. This is also, why there are so many different insect species (not actual numbers) when compared to other animal groups, the rapid, numerous reproductions, make them better suited to change (when conditions vary) than other animals, and more genetic mutations, thus more species of them.
As for the second part, there is no real need for a human to grow teeth back, we have one set that roughly last the cause overall, perfectly evolved for their job, as ominvores we need razor and grinding teeth, which we do, if we were ripping flesh from animals with no other limbs, thus losing teeth due to the force we would be using, then most probably, we would have the teeth you crave, however, with no limbs we wouldnt be able to type very well... but you would be dentist free...
