The Off-Site Dentist and the Numbing Injection
Dental hygienist Maya has practiced for six years in a Reno private office. On Friday, the dentist is at a seminar in Sacramento, about 2.5 hours away, but texts the office manager: 'I reviewed everyone's chart remotely; you can run the hygienist schedule under general supervision.' The schedule includes six recall patients for prophylaxis and fluoride. One is a 16-year-old with moderate gingivitis and no radiographs in 18 months. Another patient, a 58-year-old with scaling and root planing planned, asks for a local anesthetic before instrumentation. Maya holds a current Nevada dental hygiene license and a California local anesthesia certificate, but no Nevada anesthesia endorsement. The office has no other dentist on site. The office manager says the dentist authorized everything and asks Maya to start. Maya wants to avoid canceling six patients but is unsure about supervision and anesthesia rules.
1. May Maya treat the six recall patients while the dentist is off-site? Identify the facts she must confirm and the limits of the dentist's text authorization.

General supervision is not a blanket permission slip. Before Maya treats, she should confirm: (1) the dentist has personally examined the patient and prescribed hygiene treatment within the timeframe Nevada requires; a remote chart review may not equal an examination; (2) the office setting and procedure are authorized for general supervision; (3) the dentist is available for consultation and can return if needed; and (4) the 16-year-old's records support proceeding without new radiographs or a dentist exam. If any condition fails, she should reschedule rather than rely on the text. The dentist's message is evidence of authorization but does not cure a missing exam or an unauthorized setting. She should document the dentist's order, the date of the last exam, and any consultation. For the patient with scaling and root planing planned, she should also verify that the treatment plan and periodontal records support the procedure; if the dentist has not examined recently, the visit should wait.
2. Can Maya administer local anesthesia? What credential and supervision are required, and what should she tell the patient?
Read the worked answer
No. A California local anesthesia certificate is not a Nevada credential. Nevada dental hygienists may administer local anesthesia only after obtaining the specific Nevada certification or endorsement and while under direct supervision, meaning the dentist is physically present and immediately available. A text from Sacramento cannot satisfy direct supervision. Maya should tell the patient that anesthesia is not available at this visit, offer to proceed with non-anesthetic instrumentation if clinically appropriate, or reschedule when the dentist is on site and her credential is in place. Administering without the credential would be unprofessional conduct and could expose the patient to harm. She should not let the office manager's assurance override the credential and supervision requirements.
