United Concordia is pleased to serve the dental insurance needs of City of El Paso employees and their families. City of El Paso and United Concordia are partnering because we care about your and your family's oral health. Oral health problems often tax the immune system, which can expose you to greater risk of illness and infection. To help maintain a healthier smile and a healthier you, we encourage you to follow the advice of your dentist and the American Dental Association. Your dental plan emphasizes preventive care to help avoid costly procedures commonly caused by delayed treatment.
