Non-breastfeeding infants are at a higher risk for tooth decay when compared to breastfed babies (2, 20). Components present in human milk play a protective role. Immune factors such as Secretory IgA and IgG can slow the growth of the specific types of streptococcus mutans colonizing the child's mouth (21, 22). Lactoferrin in mothers' milk has a bacteriocidal effect (destroying bacteria), as well (6). Dr. Pamela Erickson studied the decay potential of various liquids (23, 24). Water had a decay potential of 0.00 and a 10 percent sucrose solution had a decay potential of 1.00. Human milk had a decay potential of 0.01, close to that of plain water.
