The DMO Option offers you a broad range of dental services on a pre-paid basis. The DMO Option is available in many locations and is administered by Aetna, Inc. You agree to receive care solely from dentists associated with the DMO Option network, and in return, you will have no deductibles to meet and no claim forms to file. Aetna actively works to keep dental care costs low by requiring DMO dentists to meet strict quality standards, screening for cost-effective practice patterns, and negotiating fees charged for services.
