At that point the dentist will check for any cavities in the child's primary teeth and for such early developmental problems as a bad bite. Encourage good eating habits. A balanced diet will help make sure your child has healthy teeth. Your child's diet should include a variety of foods, such as fruits and vegetables, cereals, dairy products, and meat. Protect your child's teeth with sealants.
Sealants form a barrier that keeps food and bacteria out of tiny grooves in the tooth.
They are nearly 100 percent effective in preventing decay in back teeth. Prevent nursing-bottle syndrome. Tooth decay can occur when a baby is given a bottle filled with milk, formula, or fruit juice at bedtime or for long periods during the day. Extended exposure to the sugar in these liquids can cause teeth to discolor and decay. To prevent this, clean your child's teeth after each feeding and give him or her a bottle filled only with water at bedtime.
