Children in general, should be seen by the dentist every six months to catch any small problems early. When a child is old enough, x-rays should be taken. X-rays show decay between the teeth and will also show if teeth are coming in the way they should. Fluoride application is especially important for children as well to help prevent cavities.
Once your child has permanent molars, sealants will be typically recommended to help reduce the chance of tooth decay. A sealant is a kind of plastic that is put on the chewing surface of the molars. The plastic seals the tooth and makes it less likely to trap food and germs.
Your dentist can also tell you if crooked or crowded teeth could cause problems. Sometimes crooked teeth will straighten out on their own as the child’s jaw grows and the rest of the teeth come in. If they do not straighten out, your child may have a bite problem (also known as malocclusion). This can cause problems with eating and with teeth cleaning. It can also affect the appearance of your child’s smile. Your dentist can suggest ways to treat this, or refer your child to an orthodontist.
