Dental coverage for the employee and eligible dependents is provided by the City and County and administered through Delta Dental.  Basic services and major services are subject to a $50 calendar year deductible (family deductible of $100). Employees and their eligible dependents may go to the dentist of their choice. However, using a Delta Dental PPO dentist may result in lower out-of-pocket costs because Delta has negotiated discounts with the PPO dentists.
