How to take care of your child's teeth ?

Though we all are aware of the fact that prevention is better and cheaper than cure and it is prudent to take preventive measures in health care rather than curing once we are afflicted by the disease, we seldom apply that in our practice. It is good to see that people are oriented more towards preventive measures and have started to get regular health check up and dental check ups these days. Even the children are getting more care than they used to get in the past, may be because of awareness, availability of health care facilities, or rise in the economic standard of the households. People may not have idea about how they should take care of their child's teeth even if they are willing to. This short article attempts to address the concerns of such parents.

1. When should the first dental visit be?

This is a common question people are unsure about. When should they take their children to the dentist ? The first dental visit should be at around the time of eruption of first deciduous teeth (i.e. 6 months) and not later than 1 year of age of the baby. If your child has teeth since birth (natal teeth) or if a tooth erupts within one month of birth (neonatal teeth), that may traumatize the delicate gums of the opposite arch. You need to check that on your own and consult a dentist if necessary. If your child has got cleft lip and palate since birth, the repair should be done as soon as possible consulting a oral and maxillofacial surgeon.
