The bacteria in plaque use sugar to produce acid that attacks tooth enamel. Tooth decay can occur after repeated acid attacks. For example, if a bottle containing sugary liquid is used as a pacifier many times a day, the teeth experience more acid attacks. Allowing a child to fall asleep with a bottle can also harm teeth. During sleep, the flow of saliva decreases and harmful sugary liquids collect and remain around the teeth.
Prevention is the key to healthier teeth for babies.
Caregivers should watch what they give babies between regular feedings. Don't use a bottle as a pacifier or to help a baby sleep unless it contains plain water. Don't dip pacifiers in sweet liquids, and don't add sugar to baby food. Another tip is to teach babies how to drink from a cup starting as early as age 6 months to help prevent tooth decay.
