Re: EBFed baby with tooth decay!
It depends on which source you look at on whether they believe breastmilk causes tooth decay. Most of the newer research shows that breastmilk is actually non cariogenic and actually can help to prevent tooth decay. Also while a baby is nursing the milk is going to the back of their mouth, behind the teeth, as opposed to the way the milk goes in when they are taking a bottle. The cause of decay is more than likely poor genetics. My youngest actually has weakened enamel and is very prone to decay and cavities. Our dentist has told us it is lucky we nurse and nurse for so long because that has basically saved her teeth. Had she been on a bottle or been getting milk out of a cup he believes her teeth would be much worse.
