The Dental Hygiene Board of California (DHBC) has recently enacted a regulation aimed at improving patient communication and safety. Effective March 21, 2025, all Registered Dental Hygienists in Alternative Practice (RDHAPs) are required to maintain a telephone system that includes:
- The name of their practice.
- A statement that calls will be returned within four (4) calendar days.
- Contact information for a licensed dentist to be reached in case of a dental emergency after receiving dental hygiene services. dhbc.ca.gov+1dhbc.ca.gov+1dhbc.ca.gov+1dhbc.ca.gov+1

Why This Matters
This regulation ensures that patients have clear and timely access to information and assistance, particularly in emergency situations. By providing the name of the practice and a commitment to return calls within a specified timeframe, RDHAPs demonstrate professionalism and reliability. Including contact information for a licensed dentist ensures that patients have immediate access to necessary care when the RDHAP is unavailable.
Implementing the New Requirements
RDHAPs should update their voicemail systems to reflect these patient communication changes promptly. This includes recording a message that states the practice name, the promise to return calls within four days, and providing the contact information of a collaborating dentist for emergencies. Maintaining a relationship with at least one licensed dentist for referral, consultation, and emergency services is also a requirement under 16 CCR section 1117. dhbc.ca.gov+6dhbc.ca.gov+6dhbc.ca.gov+6
Conclusion
These new communication requirements are a significant step toward enhancing patient trust and safety in alternative dental hygiene practices. By adhering to these regulations, RDHAPs reinforce their commitment to providing accessible and responsive care to their patients.
