The longer the breastfeeding, the greater the risk of tooth decay.
(New York Reuters) breastfeeding babies many, but the latest research development, breastfeeding too long and too many times, child first A tooth may have a higher risk of tooth decay.
researchers found that the greater the number of mothers breastfeeding, the greater the risk of severe early tooth decay after 24 months of age.
University of Calif San Francisco's Chafee and colleagues investigated the children of 458 low-income families in Porto Alegre, Brazil, and examined them at the age of 6, 12 and 38 months.
at the age of 6 months, the research team collected the number of bottles of milk and fruit juice every day before the baby.
in 12 months, parents will report whether they feed their children with certain foods, including fruit, vegetables, beans, animal viscera, candy, chocolate milk, cookies, honey, soft drinks or cookies.
the report, published in the Yearbook for infectious diseases, said that at the end of the survey, the researchers found that about 40% of children aged 6 months to two year old breastfeeding had tooth decay, and the rate of tooth decay increased to 48% among children who were still breast fed after two years of age.
Chafee said: "our research does not show that breastfeeding can lead to dental caries."
Bowen, a professor of oral biology at the University of Rochester, said that when a baby sucks a mother's breast or a bottle, the baby's teeth cut off the saliva of his mouth.
this physical barrier prevents saliva from decomposing bacteria and increasing the chance of tooth decay.
he also said that a bad habit is to allow a baby to contain the mother's nipple all night, which means little circulation in the saliva of the child's mouth, which can increase the risk of tooth decay.
