All you need to do to find out is answer this one simple question: Do I eat, drink, or breathe? No, really, I’m serious! Bacteria enter our mouths when we do any of those three things. Then, the little, very-very-little, bacteria do what all culprits usually do: they hide. They try to hide where you cannot reach them – at the base of the teeth, between teeth, and just below the gums. And there is not just one type of culprit; there are millions of them and of all different sorts.
Once they have found a hiding place, they invite other bacteria, other culprits, to join them. They work to create places where they can party together to destroy teeth by decay (stinky business!). By the way, if you have bad breathe? Consider that it might result from tooth decay. It can come from other factors, but if you do have bad breath, get it checked.
