What is Supplemental Dental Insurance? 

Supplemental dental insurance is an individual or family insurance policy purchased to cover some dental costs. Supplemental dental insurance will typically only cover part of the dental care procedure. The supplemental dental policy typically covers the remaining dental bill if you have a primary dental insurance plan that you purchased or your employer-provided. For example, if the dental plan policy covers half of the dental cost, the secondary or supplement dental insurance plan should cover the remaining balance of your dental procedure. You can purchase a supplemental dental insurance plan to help cover the dental charges when there are annual dental benefit plan limits or exclusions.
