HB 56 is Missouri’s bill regarding the Dentist and Dental Hygienist Compact (DDH Compact). As you may know, the DDH Compact is a comprehensive interstate licensure agreement that allows licensed dentists and dental hygienists to practice in all participating states without needing to obtain individual licenses in each one. The compact has already been enacted in 11 states, with pending legislation in 15 others.

The DDH Compact enhances licensure portability for practitioners while enabling state regulatory boards to better protect consumers through improved sharing of licensure information. Furthermore, it benefits the profession by increasing access to care for patients, preserving and strengthening the current state licensure system, and, most importantly, ensuring that each member state retains the authority to regulate the profession.

The ADHA fully supports HB 56, and we are asking our members to reach out to their legislators to express their support. Recently, on April 10, 2025, this measure passed the House chamber. Now is the time to engage with Senators and make clear just how important this legislation is. Your outreach can help ensure they understand the urgency and impact of this bill.

Missouri has a chance to expand access to quality dental care and strengthen our workforce—but we need your voice to make it happen! Legislators need to hear directly from dental hygienists like you who understand how this bill will benefit our profession and our patients.

Let’s ensure Missouri stays at the forefront of advancing oral health care—take action today!
