Our History | Delta Dental of Washington

We’ve always focused on what truly matters—your healthy smile. It drives everything we do.

A few decades ago, most adults over 50 had dentures and very few people saw the dentist unless it was an emergency.
Dental benefits didn’t exist because good oral health simply wasn’t that important. Fortunately, a small group of
Washingtonians set out to revolutionize oral health care.

In 1954, the Washington State Dental Service Corporation (now Delta Dental of Washington) was born. It was a pilot
program to help give longshoremen’s children access to dental care. It wasn’t expected to last a year, but it ended up
pioneering a new industry— dental benefits.

By 1960, we began providing plans for adults. Five years later, we joined other industry pioneers to create the Delta Dental
Plans Association. The Delta Dental system is now the largest dental benefit provider in the country and the industry leader.
