Group dental insurance is particularly flexible in both price and coverage. First, the price can depend on the copay or deductible amount, the dentists in the network, and the overall oral health of the recipients. Typically, dental insurance will cover the majority of preventative care such as cleanings, and a portion of critical care like fillings, crowns, root canals, and oral surgery. Dental insurance does not always cover cosmetic care such as implants or gum work.
