According to a recent study, published in the journal Pediatrics, children who are breastfed for 2 years or more are at higher risk of having dental cavities later.
For the research, a team of scientists analyzed breastfeeding habits and sugar consumption for 1,129 children in a city of Pelotas, Brazil. Having analyzed the given data, the researchers concluded that children who were breastfed for 2 years or longer were 2.4 times more likely to have severe cavities than children who were breastfed for less than a year.
Dr. Karen Peres, a lead author of the study and an associate professor at the University of Adelaide in Australia, explains: “There are some reasons to explain such an association. First, children who are exposed to breastfeeding beyond 24 months are usually those breastfed on demand and at night. Second, higher frequency of breastfeeding and nocturnal breastfeeding on demand makes it very difficult to clean teeth in this specific period.”
