What is the validity period for a dentist's prescription for dental hygiene services?

• A. 18 months
• B. 3 years
• C. 2 years unless a shorter period is designated.
• D. 5 years

Answer: (C)

Prescriptions for dental hygiene services are tied to a time frame to ensure ongoing oversight and periodic reassessment of the patient’s needs. In Florida, a dentist’s prescription remains valid for two years unless the dentist designates a shorter period. This default provides a clear window for the dental hygienist to perform the prescribed duties under supervision, while the dentist can re-evaluate the care plan as needed. If a shorter period is designated, that shorter period governs. After expiration, a new prescription or updated plan is required to continue hygiene services.
