WCSD offers four different dental plans, all provided by Delta Dental, depending on your dental needs. Those who choose the DMO MUST use a DeltaCare USA network dentist. For all other plans, we encourage you to find a Delta Dental PPO network dentist. Remember, if you did not sign up for the dental plan as a new hire, you will be subject to "late entrant penalties" if you decide to sign up later. This means that benefits are only payable for Preventive Services for the 12 months you are in the plan. Click the "Dental Plan Overview" button below for more details.
