Yes, you can have two dental plans! When you have multiple dental insurance policies, the two plans work together to coordinate benefits to eliminate over-billing or duplication of benefits.
The two dental insurance companies will need to participate in a Coordination of Benefits (COB) to determine which plan will pay for which services. In many states, this is required by law!
You can read more about how Coordination of Benefits (COB) works here: ADA Guidance on Coordination of Benefits
If you have specific questions regarding Coordination of Benefits between two dental plans, you should reach out directly to Renaissance Dental's customer service team at (888) 791-5995.
Below you'll see what Renaissance Dental has on their website regarding COB.
