Group dental insurance is a benefit that employers offer to their employees and their dependents to help pay for dental care. It's a type of group insurance, which is coverage that's issued to a group of people as part of an employee benefits package, rather than insurance that's purchased individually. With group dental insurance, the business or employee organization typically pays a portion of the cost, and employees typically pay a monthly premium that's deducted from their paychecks. The costs vary based on the carrier and the level of coverage.
