Use your dental benefits wisely

Here’ how to make the most of your dental benefits:


Choose a provider

Using a participating dentist in the PPO Plus Premier network will ensure you receive the highest benefits from your plan. To find a provider, go to Delta Dental.

If your service will exceed $300, request a pretreatment estimate.

You should always submit a request for a pretreatment estimate for procedures and services your dentist believes will exceed $300 (procedures such as crowns, inlays, bridges, and periodontics). For more information, call 1-800-872-0500 or visit the Delta Dental website.

Check your claim status and other information at Delta Dental.

You can review Explanation of Benefits (EOB) statements, check if claims have been paid, and more.
