Understanding what dental hygienists are expressly allowed to do helps distinguish permissible from prohibited tasks. In North Carolina, taking impressions for orthodontic adjustments is within the range of duties that a licensed hygienist can perform when the dentist directs the care. This is a noninvasive procedure that supports treatment planning and appliance fabrication without crossing into invasive or medication-related acts.

By contrast, administering anesthetics via injection and giving antibiotic agents intravenously involve medications and techniques that require higher-level authorization (such as a dentist’s or physician’s credentials). Coronal polishing is a routine hygienist task, but it must be performed with proper training; doing it without any training would not be permissible.
