How to Preventing Cavities
Earlier visits can help early detection of potential problems,
All primary teeth have come in (usually around age 2½), your dentist may start applying topical fluoride. Fluoride hardens the tooth enamel, helping to ward off the most common childhood oral disease, dental cavities (also called dental caries). Cavities occur when bacteria and food left on the teeth after eating are not brushed away. Acid collects on a tooth, softening its enamel until a hole — or cavity — forms. Regular use of fluoride toughens the enamel, making it more difficult for acid to penetrate.
Many towns require tap water to be fluoridated, others don't. If the water supply is not fluoridated, or if your family uses purified water, ask your dentist for fluoride supplements. Most toothpastes contain fluoride but toothpaste alone will not fully protect a child's mouth. Be careful, however, since too much fluoride can cause tooth discoloration. Check with your dentist before supplementing.
Discoloration can occur from prolonged use of antibiotics, and some children's medications that contain a large amount of sugar. Parents should encourage children to brush after they take their medicine, particularly if the prescription will be long-term.
Our child's permanent teeth grow in, the dentist can help seal out decay by applying a thin wash of resin to the back teeth, where most chewing occurs. Known as a sealant, this protective coating keeps bacteria from settling in the hard-to-reach crevices of the molars.
Dental research has resulted in increasingly sophisticated preventative techniques, including fillings and sealants that seep fluoride, a dentist's care is only part of the equation. Follow-up at home plays an equally important role. For example, sealants on the teeth do not mean that a child can eat sweets uncontrollably or slack off on the daily brushing and flossing — parents must work with kids to teach good oral habits health .
When Should Dental Care Start?
Proper dental care begins even before a baby's first tooth appears. Remember that just because you can't see the teeth doesn't mean they aren't there. Teeth actually begin to form in the second trimester of pregnancy. At birth your baby has 20 primary teeth, some of which are fully developed in the jaw.
Running a damp washcloth over your baby's gums following feedings can prevent buildup of damaging bacteria. Once your child has a few teeth showing, you can brush them with a soft child's toothbrush or rub them with gauze at the end of the day.
Even babies can have problems with dental decay when parents do not practice good feeding habits. Putting a baby to sleep with a bottle in his or her mouth may be convenient in the short term — but it can harm the baby's teeth. When the sugars from juice or milk remain on a baby's teeth for hours, they may eat away at the enamel, creating a condition known as bottle mouth. Pocked, pitted, or discolored front teeth are signs of bottle mouth. Severe cases result in cavities and the need to pull all the front teeth until the permanent ones grow in.
Parents and childcare providers should help young kids set specific times for drinking each day because sucking on a bottle throughout the day can be equally damaging to young teeth.
