Full coverage dental insurance typically covers diagnostic and preventative services, basic services, such as fillings, and major services, such as crowns. Not all dental insurance providers offer full coverage, but any dental insurance can offer savings.
Diagnostic and preventative services include exams, cleaning, X-rays and sealants. Full dental insurance also covers oral cancer screenings. Basic dental services include fillings and root canals in addition to the treatment of gum disease and denture repair. Major services are also covered by full coverage dental insurance and include implants, dentures and bridges. Though coverage amounts vary by plan, many plans pay 80 percent of diagnostic or preventative services, 60 percent of basic services, and 50 percent of major services.
