In California, a Dental Board investigation may begin through a patient complaint, a report from a malpractice insurer, or a referral from another licensing body. Under California Business and Professions Code Section 1670, the Dental Board of California has broad authority to investigate dentists and take disciplinary action that can range from a fine to license revocation.
For practicing dentists in Los Angeles and the San Fernando Valley, a letter from the Dental Board can be one of the most unsettling documents to receive. The investigation process is not always transparent from the outside, and a dentist who responds without understanding the procedural steps may inadvertently complicate their own position.
The information below explains how complaints reach the Board, what investigators do, and when legal counsel becomes important.
The Three Main Sources of Dental Board Investigations
The majority of California Dental Board investigations trace back to one of three sources. It’s important to understand which category a complaint falls into because it shapes the nature of the inquiry.
Patient complaints are the most common trigger. Any member of the public may file a complaint with the Dental Board through the Board’s online portal or by mail. Common complaint topics include allegations of substandard care, inadequate record-keeping, failure to obtain informed consent, billing disputes, and improper anesthesia administration. The Board is required to acknowledge receipt of a complaint and inform the complainant of the outcome in general terms once the case is closed.
Insurance and third-party referrals represent a second category. Malpractice insurers may report settlements or judgments above certain thresholds. California Business and Professions Code Section 801(c) requires insurers to report settlements exceeding $3,000 in dental malpractice claims. Hospitals and other healthcare facilities are also required to report certain adverse events and disciplinary actions taken against dental staff.
Self-reports and cross-agency referrals form the third category. Dentists are required to self-report criminal convictions, including misdemeanors related to substance use or financial crimes. The Medical Board, Pharmacy Board, and out-of-state licensing boards may also refer matters to the Dental Board when a California-licensed dentist is involved. The Dental Board of California received 5214 complaints in Fiscal Year 2025/2026.
What Happens After a Complaint Is Filed
After the Dental Board receives a complaint, a staff analyst reviews it to determine whether the conduct described, if proven, would constitute a violation of the Dental Practice Act or other applicable law. Many complaints are closed at this stage because they describe conduct that is not within the Board’s jurisdiction, such as a billing dispute that is purely a civil matter.
Complaints that clear the initial review are assigned to an investigator. The investigator may request patient records, billing records, and correspondence. They may interview the complainant, the dentist, and other witnesses.
In cases involving clinical standards of care, the Board may retain a dental expert consultant to evaluate whether the treatment met the applicable standard.
The investigation concludes with one of several outcomes: the case is closed without action, the dentist receives a citation and fine for a minor violation, the matter is referred to the Attorney General’s office for a formal accusation, or the dentist is offered a stipulated settlement to resolve the matter without a hearing.
Formal Accusations and Administrative Hearings
If the Attorney General’s office files a formal accusation, the dentist has the right to a hearing before the Office of Administrative Hearings. An administrative law judge presides over the hearing, which resembles a civil trial in many respects: both sides may present evidence, call witnesses, and submit expert testimony. The administrative law judge issues a proposed decision that the Dental Board may adopt, modify, or reject.
Possible disciplinary outcomes following a sustained accusation include revocation of the dental license, suspension, probation with conditions, a letter of reprimand, or completion of educational programs.
Dentists who receive a formal accusation have a limited window to file a Notice of Defense. Missing that deadline can result in a default decision against the dentist. This is one reason why retaining counsel early in the process matters.
How Should a Dentist Respond When a Board Investigation Begins?
The period between receiving a Board inquiry letter and the conclusion of an investigation can be the most significant. A dentist’s written responses, the records they produce, and any voluntary statements they make during an investigation can all become part of the administrative record.
Most dental license defense attorneys recommend against responding to a Dental Board inquiry without legal counsel, even for what appears to be a minor complaint. A dental board defense attorney in Los Angeles can review the complaint, assess the strength of any potential accusation, assist in compiling a complete and accurate response, and represent the dentist throughout the investigation and any subsequent proceedings.
Dentists in Canoga Park, West Hills, and the broader San Fernando Valley who receive correspondence from the Dental Board of California, whether a routine inquiry or a notice of investigation, may benefit from a legal consultation before responding.
Frequently Asked Questions
What triggers a Dental Board of California investigation?
The Dental Board of California may open an investigation following a patient complaint, a report from a malpractice insurer, a referral from another state licensing board, or a self-report by the dentist of a criminal conviction or civil judgment, as required under California Business and Professions Code Section 800.
What happens after the Dental Board receives a complaint in California?
After receiving a complaint, the Dental Board assigns it to an investigator who may request records, interview witnesses, and consult with dental experts. The Board then determines whether the complaint warrants a formal accusation or can be resolved through a lesser action such as a citation and fine.
Can a dentist lose their license over a Dental Board investigation?
Yes. If a formal accusation is filed and upheld following an administrative hearing, the Dental Board of California has authority to revoke, suspend, or place conditions on a dentist’s license under California Business and Professions Code Section 1670.
Should a dentist respond to a Dental Board inquiry without an attorney?
Most dental license defense attorneys advise against responding to a Dental Board inquiry without legal counsel. Statements made during an investigation can be used in subsequent proceedings, and an attorney familiar with Dental Board procedures can help a dentist respond in a way that protects their interests.
How long does a California Dental Board investigation take?
The timeline varies depending on the complexity of the complaint and the Board’s current caseload. Some investigations are resolved within months through a citation; formal accusation proceedings that go to an administrative hearing before the Office of Administrative Hearings can take considerably longer.
