This quote seems like it can't possibly be true—is it? One would imagine that even if you avoided kissing anyone your entire life, you'd still get cavities. > Babies have no existing mouth bacteria, and get theirs from their parents’ kisses. Not necessarily their first kiss as a newborn (newborns have no teeth, and BCS3-L1 needs teeth to live), but their first kiss after teeth grow in. If you get this, you’re probably getting it for your whole future family line.
