Organized dentistry: how the ADA, state and local societies fit together

This guide explains how organized dentistry is built and how a dentist can take part. It is general education from Copeland Consulting Services, based on the ADA, the Missouri Dental Association (MDA) and the Greater St. Louis Dental Society (GSLDS). It does not tell any dentist whether to join. That choice depends on your goals, your budget and your state’s offerings.

What is organized dentistry?

Organized dentistry is the system of professional dental societies that works at the local, state and national levels. In the United States, the American Dental Association (ADA) sits at the national level. State societies and local societies sit below it. Together they set policy, speak to lawmakers, provide member services and publish ethical standards.

The word “organized” separates this network from individual practices and from other groups such as academies or study clubs. Those groups are valuable, but they follow different structures. The term in everyday use points to the ADA, the state societies and the local societies. Read the organized dentistry glossary entry for a short definition. The post what is organized dentistry goes through the history and vocabulary.

What does tripartite mean?

Tripartite means composed of three parts. The ADA uses the word for its membership model. The three parts are the component (local) dental society, the constituent (state, district or territory) dental society and the ADA itself. The ADA says each level offers its own benefits and resources.

The ADA states that its tripartite structure fosters coordinated efforts on behalf of dentistry. It also says the national ADA works with state and local societies to provide resources and services to practices, to educate the public and to seek ways to ensure access to oral health care.

The ADA also says that almost all U.S. dentists are tripartite members and that they join and maintain their memberships through their constituent society. Dental students join through the American Student Dental Association. A small number of other categories can join the ADA directly.

How is the ADA governed?

The ADA has a legislative body and a managing body. The ADA describes its House of Delegates as the Association’s legislative body and its Board of Trustees as the Association’s managing body. Councils serve as policy recommending agencies in their areas of expertise.

The ADA lists 10 councils. Most are made up of one member from each of the 17 trustee districts, plus one new dentist member. Council topics include dental benefit programs, dental education and licensure, dental practice, ethics and bylaws, and government affairs. See the ADA governance page for the full list.

The House of Delegates is the ADA’s legislative body, where policy resolutions are considered. The post on the ADA House of Delegates covers how resolutions move. The ADA also notes that national membership costs are set each fall by its House of Delegates.

What is the New Dentist Committee?

The New Dentist Committee is an advisory committee to the ADA Board of Trustees. The ADA says it supports and advocates for new dentists and dental students. It has 17 members, one from each ADA district. It recognizes peers through the ADA 10 Under 10 Award and runs student events such as the ADA Success Program. See the ADA 10 Under 10 Award for the program’s details.

How is organized dentistry set up in Missouri?

In Missouri, one membership covers three levels. The MDA says that when dentists join the MDA, they do so at three levels: the local component, the state (MDA) and the national (ADA).

The MDA lists eight component societies. Four are staffed, with an executive director and officers. Four are non-staffed and run by officers only.

The GSLDS says it was founded in 1856 and has more than 1,000 local member dentists. It describes itself as the local component of the MDA and the ADA. Its website lists member benefits, continuing education and an annual convention called the Mid-Continent Dental Congress. Check each society’s own website for current events, dues and contacts, since officers and programs change.

The MDA site also lists member resources. These include a New Dentist section, advocacy and PAC pages, a Missouri Dental Practice Act page, a House of Delegates page and CE accreditation. The MDA’s mix of resources is a reasonable starting list when you ask a society what it offers.

For Missouri rules about continuing education, see Missouri dental CE requirements.

How do you find your society?

Start with the state society, because the ADA says most dentists join and maintain membership through it. The ADA runs a directory of state society information and resources. The MDA’s component page lists the eight Missouri components and links to each one’s website.

Follow these steps:

1. Find your state society through the ADA directory, or go to the MDA site for Missouri.
2. Find the local component that covers your county. Ask the state society if the map is unclear.
3. Read the component’s website for events, dues and contacts.
4. Call or email the executive director if the component is staffed, or an officer if it is not.
5. Ask for a combined dues quote for all three tiers.

The ADA FAQ advises dentists to reach out to their state dental society as soon as they begin to practice, so they get the most out of ADA membership at the local level. It adds that if you move, you should tell both your original local and state societies, then contact the societies at your new location.

What does membership cost?

Membership cost has a national part and a local part. The ADA says national dues are set each fall by its House of Delegates, and that in 2026 the full national cost for an ADA member is $627. State and local dues vary by location. Recent graduates, graduate students, international members and retired members pay reduced rates.

The ADA suggests entering your information in its dues tool to find your combined costs. Ask your state society for the total across all three tiers. Ask your CPA about how association dues are treated on your return. This guide does not give tax advice.

What does the ADA Code of Ethics have to do with membership?

Members agree to follow the ADA Code. The ADA Principles of Ethics and Code of Professional Conduct says members voluntarily agree to abide by it as a condition of ADA membership. It describes the Code as a written expression of the obligations arising from the implied contract between the dental profession and society.

The Code also says ethics and the law are closely related but not the same, and that ethical obligations may exceed legal duties. The post ADA Code of Ethics explained summarizes the structure. The code of ethics entry gives a one-line definition.

What does organized dentistry do on policy?

Societies work on policy in several ways. At the national level, the ADA House of Delegates adopts policy. At the state level, a society such as the MDA runs advocacy programs and a political action committee. The MDA’s site lists an Advocacy and PAC page and a Dental Day at the Capitol event.

Read each society’s own pages for current priorities. Policy positions change with each legislative session. This guide does not take sides on any bill or ADA resolution.

How can a dentist get involved?

A dentist can take part at any of the three levels. Here are practical steps, listed from lowest to highest time commitment:

1. Read your state society’s newsletter or website.
2. Attend one local meeting or continuing education event.
3. Ask the society what committees need members.
4. Join a committee or the local board.
5. Stand for election as a delegate or an officer.

The MDA’s component page notes that members often think they do not have time to take part in organized dentistry. It points to a video and to volunteer options at the state and national levels. The page offers resources to any member who volunteers in a component.

Questions worth asking any society before you join:

What are the ADA’s councils?

The ADA lists 10 councils. Each covers a policy area. Most meet twice a year, and members must be active, life or retired members in good standing.

The table shows names only. Read the ADA governance page for what each council does.

How does organized dentistry compare with other dental groups?

Organized dentistry is one part of a larger set of dental groups. Study clubs focus on peer learning. The Academy of General Dentistry focuses on general dentists and continuing education, as covered in AGD fellowship and mastership. Each group has a different purpose and different dues. Many dentists join more than one.
