Prescribing, Anesthesia, and Other Restricted Activities
Prescribing is dental
In Nevada, prescribing medications and issuing orders for drugs is part of dentistry. Dental hygienists do not have independent prescribing authority. A hygienist may administer or apply a medication only when it is within hygiene scope, authorized by the dentist, and permitted by regulation. Calling in a prescription for a patient is outside scope even if the dentist is busy.
Anesthesia and sedation permits
Local anesthesia, nitrous oxide, and sedation are restricted activities. A dentist must hold the required permit and meet training and equipment standards. A hygienist may administer local anesthesia only if she holds the specific Nevada credential or permit, has completed the required course, and works under the supervision level the Board requires. Sedation generally remains a dentist-level responsibility.
Emergency and adjunctive drugs
Emergency protocols may allow a hygienist to assist with oxygen or reversal agents under office protocol, but that is not general prescribing. Vaccines, controlled substances, and therapeutic drugs require dentist authority and applicable law.
Worked example
A patient calls with pain and the dentist is unavailable. The hygienist wants to phone in an antibiotic 'just this once.' She may triage, document, and contact the dentist or covering dentist, but she may not prescribe. The lawful prescription must come from a dentist or other authorized prescriber.
Traps
A collaborative or public-health setting does not automatically create prescribing rights. A certificate from another state does not substitute for a Nevada permit. 'The dentist told me to' does not authorize a task the hygienist is not credentialed for.
