A dental practice act is a state law that defines who can legally provide dental care, what procedures each type of provider can perform, and how the profession is regulated. Every U.S. state and territory has its own version, which means the specific rules governing dentistry vary depending on where you live or practice. These laws exist to protect patients by setting minimum standards for education, licensing, professional conduct, and disciplinary enforcement.
Why Dental Practice Acts Exist
State legislatures pass dental practice acts under their authority to protect public health. Washington State’s law captures the reasoning plainly: the health and well-being of residents are “of paramount importance,” and licensed dental professionals play a vital role in preserving that health. The law also acknowledges that without a formal system for handling disciplinary proceedings, there is no effective way to hold practitioners accountable when patient safety is at risk.
In practical terms, a dental practice act creates the legal framework for a state dental board or commission. That board then carries out the law’s intent by issuing licenses, setting standards of practice, investigating complaints, and disciplining providers who violate the rules. The Tennessee Board of Dentistry, for example, describes its mission as safeguarding health, safety, and welfare by ensuring that dentists, dental hygienists, and dental assistants are qualified to practice. The board interprets the laws and regulations to determine appropriate standards of professional conduct.
What a Dental Practice Act Covers
While the details differ from state to state, most dental practice acts address the same core areas:
- Licensing requirements. Who qualifies for a license, what education and examinations are needed, and how licenses are renewed.
- Scope of practice. Which procedures dentists, hygienists, and dental assistants are legally permitted to perform.
- Continuing education. How many hours of ongoing training are required to maintain a license.
- Professional conduct. Standards for recordkeeping, patient communication, informed consent, and ethical behavior.
- Disciplinary authority. The grounds for investigation, the types of penalties the board can impose, and the process for hearings and appeals.
- Prescriptive authority. Rules governing what medications dentists can prescribe, particularly controlled substances.
Because each state writes its own act, a procedure that a dental hygienist can legally perform in one state may be off-limits in another. This is one of the most important practical consequences of having 50 separate practice acts rather than a single national standard.
Licensing and Continuing Education
Every dental practice act requires practitioners to hold a valid license before treating patients. To obtain that license, a dentist typically needs a degree from an accredited dental program and a passing score on both a national written exam and a clinical licensing exam (which varies by state or region).
Keeping that license requires ongoing education. Illinois, as one example, requires dentists to complete 48 hours of continuing education every three years. Dental hygienists in the same state need 36 hours over the same period. No more than half of those hours can come from correspondence or online-only courses, and no more than half can come from teaching. These caps are meant to ensure that practitioners engage in a variety of learning formats. Notably, Illinois does not require continuing education for the first renewal after initial licensure, giving new graduates a brief grace period.
The specific hour requirements and acceptable course types vary by state, so practitioners who move or hold licenses in multiple states need to track each jurisdiction’s rules separately.
Scope of Practice for Dental Assistants
One of the more complex areas of any dental practice act involves what dental assistants and expanded-function dental assistants can do. These roles exist on a spectrum, and practice acts define each level carefully.
In California, for instance, a registered dental assistant in extended functions (RDAEF) can perform certain procedures independently, but the boundaries are specific. An unlicensed dental assistant can apply fluoride varnish because it is classified as a non-toxic topical agent. Assistants certified in coronal polishing can use a slow-speed handpiece with a rubber cup and polishing agent, but are not permitted to cut hard or soft tissue. No expanded-function assistant can start or remove IV lines or administer medications through an IV unless they hold a separate nursing license. These distinctions illustrate how granular practice acts can be. A single procedural step, like using a particular type of handpiece, may be permitted under certain conditions and prohibited under others.
Prescribing Rules and Controlled Substances
Dental practice acts, often working alongside state pharmacy and controlled substance laws, define what dentists can prescribe and under what circumstances. This is especially relevant for pain management after procedures like extractions or oral surgery.
Florida’s rules offer a detailed example. Dentists prescribing controlled substances for acute pain must conduct and document a medical history and physical examination. The law defines acute pain specifically as the normal, time-limited response to surgery, trauma, or acute illness, excluding cancer pain, palliative care, and terminal conditions. Dentists must also check the state’s Prescription Drug Monitoring Program (PDMP), an electronic database that tracks controlled substance dispensing. Patients with a history of substance abuse or psychiatric conditions require extra care, monitoring, and documentation, and the dentist may need to consult with or refer to a specialist. Every state now operates a PDMP, and most dental practice acts require dentists to query it before writing certain prescriptions.
Disciplinary Actions and Enforcement
When a dental board receives a complaint about a practitioner, the practice act gives it authority to investigate, hold hearings, and impose penalties. Those penalties can range from a formal reprimand or mandatory additional education to license suspension or permanent revocation.
A 2025 study in the Journal of the American Dental Association analyzed over 1,000 disciplinary actions against general dentists in Texas and found that the most common reason for sanctions was inadequate recordkeeping, accounting for 39% of all infractions. Inadequate treatment and lack of ethics or professionalism each represented 23%. Improper diagnosis made up 9%, and renewal issues accounted for 6%. The fact that poor documentation is the single largest category underscores how seriously boards take recordkeeping, not just clinical skill. Incomplete records make it difficult to evaluate whether a dentist met the standard of care, and they leave patients vulnerable if they need to transfer to another provider or pursue a complaint.
Patient Record Requirements
Dental practice acts typically include provisions on how long dental offices must retain patient records after the last visit. The exact timeframe varies by state, and for minors, most states require records to be kept for a set number of years after the child reaches the age of majority (usually 18). Federal privacy rules add another layer: HIPAA compliance documents, including written policies and training records, must be retained for at least six years from creation or from the date they were last in effect, whichever is later.
Because requirements differ so widely, the American Dental Association recommends that every practice maintain a written records retention policy and ensure all staff understand and follow it.
How Practice Acts Handle Teledentistry
As remote healthcare has expanded, dental practice acts have had to adapt. A cross-sectional study conducted between September 2024 and January 2025 found that 47 out of 51 U.S. jurisdictions (including Washington, D.C.) now permit some form of teledentistry. Among those, 87% allow both live video visits and asynchronous services (like reviewing submitted photos or records at a later time), while about 13% restrict teledentistry to live video only.
The rules around who can deliver care remotely also vary. About 72% of jurisdictions that allow teledentistry permit hygienists or other licensed providers to deliver services, not just dentists. Informed consent for teledentistry visits is mandated in 57% of these jurisdictions. Only about 6% require patients to have an existing relationship with the provider before a remote visit, while the majority impose no such requirement.
This patchwork creates real challenges. A dentist licensed in one state generally cannot treat a patient located in another state via teledentistry unless they also hold a license there. Direct-to-consumer orthodontic companies, which initiate treatment plans remotely and sometimes without a comprehensive in-person exam, have raised particular concern. The American Association of Orthodontists supports teledentistry for improving access to care but has taken a clear position that an in-person examination should precede any orthodontic treatment. No state currently provides explicit guidance on the use of artificial intelligence in teledentistry.
How to Find Your State’s Practice Act
Every state dental board publishes its practice act, usually on the board’s website or through the state legislature’s online database. Searching for “[your state] dental practice act” or visiting your state dental board’s site will get you to the full text. Many state dental associations also publish plain-language summaries that are easier to navigate than the raw statutes. If you hold licenses in multiple states, each one’s rules apply independently to the care you provide in that jurisdiction.
