Naaah, this is not how evolution works. Tooth decay was not as big of a problem for our ancestors than it is for us (more sugar and acidic soft drinks) and tooth decay becomes more of a problem for older people that already reproduced making good teeth above a certain age uninteresting from an evolutionary standpoint. (And mayebe instead of better teeth we learnded to feed grandparents soft porridge to keep them around longer for babysitting duties ;-) (see the usefulness of aunts in elephants). Just because you like to keep your teeth, doesnât mean that nature cares.
