Dental insurance is a type of health insurance that helps cover the costs of dental care. It typically includes services like routine check-ups, cleanings, fillings, and sometimes more extensive procedures such as crowns or root canals. Most plans require a monthly premium and may have deductibles and co-pays. There are different types of dental insurance plans, including preferred provider organizations (PPOs) and health maintenance organizations (HMOs). PPOs offer more flexibility in choosing dentists, while HMOs usually require members to select a primary dentist. Coverage levels and costs can vary, so it's important to review plan details before enrolling.
