Many people do not receive dental benefits though their employer. Dental insurance is often not though about until there is a larger dental issue that needs to be address. Yet buying dental insurance only when a dental issue arises is not a good idea for anyone. By doing so you may either need to give up your current dentist or not receive the benefits you could have had, had you though ahead of time. This is especially true with regards to babies.
Most babies will need to see a Pediatric Dentist until they are at least five to six years of age, until they can start seeing a more affordable family dentist. By buying a dental PPO plan while your baby is still a new born you are able to not only see the dentist you wish, but by the time your child is one year old (recommend time a baby should first see a dentist) any plan waiting periods are either over or will be over shortly. This is because generally speaking PPO plans have a six month waiting period for basic services and 12 months waiting periods for major dental care services. Hopefully your one year old will not be needing any major dental care services but it nice to know you will have dental benefits available if need be.
