I guess I'm not very clear on what "genes" are...

But like... I can see how your braces scenario doesn't work..

But if say a to-be-mum/dad has good calcium intake, wouldn't that MIGHT make their baby have healthier teeth or something?

Like having braces just alters the appearance, doesn't really change any cells in your body the way food/smoking/alcohol does...

Though, at the same time I think it probably doesn't make a HUGE difference... like maybe a dad is already carrying lung cancer pron genes, and if he smokes too it might make it worse.. but even if he doesn't smoke, he would still pass on the lung cancer pron genes to the kid....

I dont know, I'm just making stuff up LOLOL
