Dental insurance provides coverage to help pay for dental care costs. There are several common types of dental insurance plans, including preferred provider organizations (PPOs), dental health maintenance organizations (DHMOs), indemnity plans, and direct reimbursement plans. PPOs allow patients to receive care from a network of dentists who charge reduced fees. DHMOs provide comprehensive care through designated provider offices for a fixed monthly fee paid per enrolled patient. Dental insurance helps provide access to dental care and reduces costs for major dental procedures.
