Icon for the answer

The dental hygienist must become licensed to practice dental hygiene in New York State and apply for New York State anesthesia certification. The education completed previously would be reviewed by the State Education Department to determine whether or not it is equivalent to New York State's educational and training requirements for certification. If a dental hygienist's education and training is not found to be equivalent, he or she may be required to complete additional didactic coursework or clinical training before certification.
