Which entity must be notified upon a dentist's retirement?

The Nevada State Board of Dental Examiners must be notified upon a dentist's retirement because it is a regulatory body that oversees licensed dental practitioners in the state. This notification is part of the legal obligation a dentist has when changing their professional status. By informing the Board, the dentist ensures that their license is appropriately updated to reflect their retirement status, thereby preventing any potential legal issues that could arise from continuing to maintain an active license without practicing.

Notifying the Board also helps maintain the integrity of the dental profession by keeping accurate records of who is currently licensed to practice. This is crucial for consumer protection and for maintaining public trust in the profession. The process typically involves submitting a written notice or application to avoid any misunderstandings regarding the dentist's professional status.

In contrast, the other options do not fulfill the legal and professional obligations of a retiring dentist. Informing a local health department, posting on social media, or notifying patients directly, while potentially useful for communication, does not replace the necessity of formally notifying the Board, which is the authoritative entity governing dental practice in Nevada.
