Sharper focus. Smarter benefits. It’s that simple.

Since 1967, Delta Dental of Illinois has been providing dental benefits for Illinois-based groups and their enrollees nationwide – while helping to control dental benefits costs and improve access to dental care – as part of our overall commitment to improving the oral health of the people of Illinois.

With over 45 years of focus, we know our stuff when it comes to dental benefits. Groups can rely on us for flexible plan designs, smart cost-saving strategies and extensive oral health knowledge. We know dental benefits better, so we’re able to deliver better dental benefits. It’s as simple as that.

From our Naperville Service Center, Delta Dental of Illinois provides comprehensive, single-site plan administration to 5,000 Illinois-based groups of all sizes – covering 2 million employees and their family members nationwide.

Delta Dental of Illinois also works hard to provide support and funding for important projects that help our neighbors. Through the Delta Dental of Illinois Foundation, we are able to reinvest in our communities and create momentum for important causes statewide – especially those that share our mission to improve oral health.

Whatever the size of your group, we have a dental plan that makes sense for your company and your employees. We also offer DeltaVision Plans and life and disability products.
