Are the dental guidelines any good though in the sense of people actually brushing their teeth and eating properly so as to reverse the damage? Dentists are one of the few professions I've found that will happily chastise their customers, and often rightly so, for failing to adhere to proper dental maintenance. In that case I could understand just going ahead with a filling even if technically and ideally the decay could be reversed, simply because most people probably won't do what's necessary.
