The Centers for Medicare and Medicaid Services (CMS) administers Medicare, the nation's largest health insurance program, which covers nearly 40 million Americans. Medicare is a health insurance program for people 65 years of age and older, some disabled people under 65 years of age, and people with end-stage renal disease (permanent kidney failure treated with dialysis or a transplant).

Medicare does not cover most dental care, dental procedures, or supplies, including cleanings, fillings, tooth extractions, dentures, dental plates, or other dental devices.
