Dentists and Dentistry - As introduced, requires the commissioner of health to create programs designed to enhance access to dental services in rural and underserved areas subject to the approval of the commissioner of finance and administration. - Amends TCA Title 63, Chapter 5 and Title 68.

HB 643 requires Tennessee's Commissioner of Health to create programs improving dental access in rural and underserved areas, directly affecting residents in those communities. Key provisions include partnering with dental schools, upgrading clinics, offering provider incentives, supporting senior dental care, and using technology to expand services. All programs must first get approval from the Commissioner of Finance and Administration. The bill explicitly states it does not allocate funds - any spending would require separate legislative appropriations.
