Local anesthesia administration is not included as a function of dental hygiene licensure; it may only be performed by dental hygienists who have been separately certified by the committee to perform the expanded function. The administration of local anesthesia requires the indirect supervision of a dentist. Local anesthesia may only be administered by a dental hygienist under general supervision as outlined in 16.5.28.11 NMAC.
