Tooth decay increases your chances of getting heart disease by a fair bit. Not only that, you'll need false teeth by the time you're in your thirties. You wont meet anybody that wants to stay with you as well, because your breath smells like an arse hole... So yeah, a pretty miserable and short existence until you die, for the sake of not going to the dentist.
Tooth decay gives you heart disease?
That's like saying watching girls poo gives you a boner. Totally random and unrelated.
