Children should not be put to bed with or fall asleep with a bottle containing anything other than water. Nursing or bottle feeding just before bed can cause a tremendous increase in the risk of tooth decay. Always make sure that the milk or formula has been cleaned from their teeth before falling asleep. Feeding with a bottle should be ceased by 12–14 months of age to lower the risk of decay. Drinking juice or any sweetened drinks from a bottle should be avoided.
At first, cleaning the teeth can be done without toothpaste or with a non–fluoridated, infant/toddler toothpaste. Once your child has the ability to spit (usually age 2–3), you can start using a fluoridated toothpaste twice a day. All you need is half a pea-sized amount.
