What is "baby bottle tooth decay"?

Baby bottle tooth decay is an advanced decay of the teeth caused by the constant dripping of milk into a baby's mouth. Baby bottle tooth decay happens because of the way baby bottles are formed. When you tip the bottle just right, the milk just drips into the baby's mouth, without the baby having to stop it or interact at all. This constant dripping of milk can lead to the milk sitting on the baby's teeth and causing decay over time.
