A common question asked by breast-feeding mothers is can breast milk cause cavities? My response to this is that breastmilk alone does not cause cavities! Here are some reasons why:
Although breastmilk contains lactose (a milk sugar), it is NOT considered cariogenic due to it being a non-fermentable sugar. This means bad bacteria cannot metabolize it and produce an acid byproduct -which causes demineralization to teeth causing cavities. Other beneficial components that breast milk has included:
-IGA and IgG (immunoglobulins found in breast milk) which slows strep mutans growth. Strep mutans is one of the main bad bacteria in the mouth that is responsible for cavities.
-Lactophyren (an enzyme in breast milk) has bactericidal actions, thus keeping overgrowth of bacteria at bay.
-Casein (a protein in breast milk) can enhance remineralization of teeth as well as calcium and phosphate found in Brest milk.
Some reasons babies may develop cavities include:
-Using formula which contains man made carbohydrates which are cariogenic.
-Babies that mouth breath which dries out the mouth causing the pH level to become more acidic causing demineralization.
-Frequent feeding or feeding on demand which leads to more acid attacks to the teeth. Exclusively breast-fed babies can have this problem if they have genetically softer teeth due to poor enamel development.
-Compromised or less than optimal oral microbiome. A baby‘s oral microbiome is a blank slat until vaginal bacteria or skin bacteria from a C-section is introduced. Bacteria is also introduced via saliva/ kissing. Thus, the health and oral health of the mother is very important to create a healthy start for their baby. It is recommended to not kiss your baby on the mouth or share utensils etc. especially if you yourself have oral health problems because you can pass that bad bacteria to your baby and cause a dysbiosis.
