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 like crowns or root canals. Most plans require a monthly premium and may have deductibles or co-pays for certain services. Many employers offer dental insurance as part of their benefits package, but individuals can also purchase it independently. Coverage can vary widely between plans, so it's important to review the details to understand what services are included and any limitations that may apply.
