Waiting to Brush

Dental expert: It's disconcerting that the entire global dental profession seems to be promulgating this advice based on so little actual evidence. Maybe it really is best for the teeth to wait 30 or 60 minutes or brushing. But do you know if that's actually what people do in response to hearing that advice? The history of public health is filled with examples when experts promoted advice that should have kept people safe, but in effect, it ended up doing the opposite.
