How to Choose the Right Business Entity for Your Dental Practice

Recent Trends in Dental Practice Structuring

In the past several years, an increasing number of dental professionals have moved away from sole proprietorships toward limited liability entities such as professional limited liability companies (PLLCs) and professional corporations (PCs). This shift has been driven by a combination of tax reform, state-level regulatory changes, and a broader awareness of personal asset protection. Many states that once limited professional entity options have expanded their statutes, while others have tightened requirements around ownership and control. Group practices and multi-location models are also prompting dentists to revisit their initial structures earlier than expected.

Why Business Entity Selection Matters

The choice of business entity directly affects a dentist’s personal liability exposure, tax obligations, and ability to bring in partners or sell the practice. Key distinctions include:

• Liability protection – Entities like PLLCs and PCs can shield personal assets from business debts and malpractice judgments, though they do not eliminate professional liability for one’s own actions.
• Tax treatment – Pass-through entities (sole proprietorships, partnerships, S corporations, many LLCs) avoid double taxation, while C corporations face corporate tax rates but offer certain fringe benefits and retained earnings strategies.
• Ownership restrictions – Most states require that only licensed professionals own shares or membership interests in a dental practice. Structures must comply with “corporate practice of dentistry” doctrine.
• Succession and exit planning – Different entity types impose varying degrees of difficulty when adding associates, transferring ownership, or selling the practice.

Common Factors Dentists Weigh

When selecting an entity, practitioners typically consider the following variables, often with guidance from a business advisor or attorney:

• Personal vs. practice liability – High-risk procedures or a history of litigation often push dentists toward PLLCs or PCs that provide stronger separation.
• Tax bracket and income level – Solo dentists in higher marginal brackets may benefit from S corporation taxation to reduce self-employment taxes, whereas lower-income practices might prefer simpler pass-through structures.
• Number of owners – A sole owner has more flexibility; multiple owners require partnership agreements or operating agreements that clarify profit splits, decision-making, and buyout terms.
• State regulations – Some states mandate specific entity types for dentists (e.g., PC only), while others allow PLLCs but require annual filings or physician ownership caps.
• Future growth plans – Dentists planning to hire associates with a path to partnership or to merge with a larger group often opt for structures that accommodate easy equity adjustments.

How the Right Entity Affects Practice Growth

Selecting an appropriate entity early can streamline expansions and reduce friction later. For instance, a well-structured PLLC with an operating agreement that includes admission procedures makes it easier to bring in a new partner. Conversely, a sole proprietor who remains unincorporated may face tax complications when adding a partner or selling the practice. The entity choice also influences borrowing capacity—lenders often prefer incorporated practices because they offer clearer asset separation and financial records. Further, group practices structured as multi-member LLCs or PCs can allocate income and losses flexibly among owners, aiding tax planning during growth phases.

Regulatory and Tax Developments on the Horizon

Several evolving factors could affect entity choice for dental practices in the near to medium term. State legislatures are revisiting corporate practice of dentistry rules, with some moving to allow non-dentist ownership under certain conditions. At the federal level, potential changes to pass-through taxation and S corporation rules may alter the cost-benefit equation for smaller practices. Additionally, the increasing prevalence of dental service organizations (DSOs) is prompting solo practitioners to consider structures that facilitate future affiliation without triggering a full sale. Dental professionals should monitor these developments and review their entity type every two to three years, or whenever a significant business event occurs.
