Modifies provisions relating to the scope of practice of dental hygienists

HB 2137 modifies Missouri's rules for dental hygienists, primarily requiring them to work under the supervision of a licensed dentist in most settings. The bill creates two key exceptions: (1) hygienists can provide basic services like oral screenings and fluoride varnish in any location without a dentist's supervision, and (2) experienced hygienists (with 3+ years in public health) can perform cleanings, sealants, and fluoride treatments for Medicaid-eligible children without supervision, with Medicaid reimbursing providers. This directly affects dental hygienists, dentists, public health facilities, and Medicaid-eligible children. The changes aim to expand access to preventive dental care in community settings while maintaining oversight for more complex procedures.
