Our history

In 1954, dentists and employers recognized the need to increase access to oral health care and formed dental service organizations in California, Oregon and Washington. Led by Delta Dental of Washington (DDWA), we began to build dental insurance programs for employees.

In 1966, Delta Dental Plans Association was created in order to coordinate dental insurance for companies with employees in multiple states.

A year later, DDWA partnered with the International Association of Machinists to create the first multi-state dental benefits program.

When Delta Dental of California was chosen as the dental insurance carrier for the Office of the Civilian Health and Medical Program of the Uniformed Services (OCHAMPUS) program, other Delta Dental companies agreed to share their dentist data in order to centralize the administration of the account. This resulted in the creation of the National Provider File (NPF) and the establishment in 1990 of DeltaUSA®—the company responsible for overseeing our dentist data and enabling the administration of national business accounts.

Today, Delta Dental Plans Association is comprised of a network of 39 independent Delta Dental companies operating in all 50 states, Puerto Rico and other U.S. territories, and together we provide coverage to more Americans than any other dental insurance company.
