You can make a report to the Dental Board of California. here is the link: http://www.dbc.ca.gov/consumers/complaint_info.shtml
Your friend can make a Dental Board complaint, and also a police report. Most of all your friend needs to stop notwithstanding the difficulties of finding replacement employment. Your friend is risking criminal prosecution, including jail time, along with onerous fines and loss of the Dental Assistant license for life. No employment is worth the jeopardy that your friend is at risk of by practicing dentistry without a license.
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
