A form of medical health insurance that covers treatment and care of gum disease is called?

The correct choice is dental expense insurance, which specifically covers the costs associated with dental care, including treatments related to gum disease. This type of insurance is designed to address various dental health needs, ranging from preventive care like cleanings and check-ups to more extensive procedures involving treatment for gum diseases such as gingivitis or periodontitis.

Dental expense insurance is distinct from other types of medical insurance like major medical plans, which primarily focus on broader medical coverage including hospital stays, surgical procedures, and inpatient care, but may not fully address specific dental issues. Medicaid could provide coverage for some dental services, but it varies by state and generally has limitations. A franchise health policy, on the other hand, is a type of insurance that provides benefits on a group basis but may not specifically cater to dental procedures and treatments.

By offering targeted support for dental treatments, dental expense insurance is the most appropriate option for covering the treatment and care of gum disease.
