How can I best care for my child's teeth? Toothbrush Good dental hygiene habits should begin before your child's first tooth comes in. Wiping your baby's gums with a soft damp cloth after feedings helps to prevent the buildup of bacteria. When teeth appear, start using a soft children's toothbrush twice a day. Once your child is preschool-age, start using fluoride toothpaste. Don't cover the brush with toothpaste; a pea-sized amount is just right (see picture above). Young children tend to swallow most of the toothpaste, and swallowing too much fluoride toothpaste can cause permanent stains on their teeth. What about using fluoride tablets? Fluoride helps make teeth strong by hardening the tooth enamel. Many cities are required to add fluoride to tap water. If you live in an area where the tap water doesn't contain fluoride, your doctor may prescribe daily fluoride tablets when your child is about 6 months old. Fluoride is an important part of your child's dental health, but don't give him or her more than the directions call for. If you miss a dose, don't give your child extra fluoride to make up. Just as with swallowed toothpaste, too much oral fluoride can cause stains on your child's teeth. What are cavities? Cavities are holes that are formed when bacteria (germs) in your mouth use the sugar in food to make acid. This acid eats away at the teeth. Cavities are the most common disease in children. Good tooth care can keep cavities from happening in your child Is my child at risk for cavities? Your child might be at risk for cavities if he or she eats a lot of sugary foods (such as raisins, cookies and candy) and drinks a lot of sweet liquids (such as fruit juice and punch, soda and sweetened drinks). Your child also might be at risk if he or she has any of the following risk factors: * Was born early (prematurely) or weighed very little at birth (low birth weight) * Has ongoing special health care needs * Has white spots or brown areas on any teeth * Does not go to
