How many dental hygienists can a dentist employ in their practice?

The correct answer is that a dentist can employ up to three full-time hygienists for each actively practicing dentist. This limitation is based on regulations that ensure proper oversight and management within a dental practice. By allowing a maximum of three hygienists per dentist, it helps maintain the quality of care and effectively manages the delegation of responsibilities within the office. This regulation supports the role of the dentist as the primary provider while allowing flexibility in staffing to meet patient needs without compromising oversight or care quality.

The other options do not accurately reflect the regulations governing the dentist-dental hygienist relationship, which aim to ensure safe and responsible practice management.
