When should my child start seeing a dentist?

The ADA recommends your child see a dentist not later than his or hers first birthday.  Tooth decay can start as soon as your child's first tooth erupts.  Parents often ask us why they should worry about tooth decay in baby teeth since they will be replaced by permanent teeth.  The problem is that decay in primary teeth could mean a higher risk of decay in the permanent teeth.  Severe decay can also harm your child's overall health.
