How to Become a Certified Expanded Functions Dental Assistant in Germantown, TN

How to Become a Certified Expanded Functions Dental Assistant in Germantown, TN

The U.S. Bureau of Labor Statistics projects continued demand for dental assistants over the next decade, and expanded functions can make candidates more competitive in the job market.

If you’re a dental assistant in Germantown, TN, you’ve probably hit a ceiling. Same duties, same pay, limited growth. Becoming an Expanded Functions Dental Assistant (EFDA) can significantly expand your scope, responsibilities, and earning potential.

This post covers exactly what an EFDA is, what Tennessee requires, and how to find EFDA jobs in Germantown once you’re certified.

What Is an Expanded Functions Dental Assistant?

An Expanded Functions Dental Assistant (EFDA) is a dental assistant with advanced clinical training who performs specialized procedures directly on patients under a licensed dentist’s supervision.

Standard dental assistants support the dentist. EFDAs deliver hands-on care. That’s the core difference.

Common expanded functions in Tennessee include:

  • Applying dental sealants to protect teeth from decay

  • Performing coronal polishing to remove plaque and surface stains

  • Applying topical fluoride and a topical anesthetic

  • Taking dental impressions

  • Restorative and prosthetic functions, including placing restorations (this specific function requires a higher experience threshold—covered below)

  • Nitrous oxide monitoring

  • Dental radiography

Do EFDAs Earn More Than Standard Dental Assistants?

Generally, yes. According to DANB, dental assistant salaries can vary between $20 and $30 per hour or more, depending on certification level, experience, and geographic location. EFDAs — with their advanced certifications and expanded clinical scope — typically sit toward the higher end of that range.

The pay difference comes down to scope. EFDAs handle procedures that would otherwise require a hygienist or dentist. That additional clinical responsibility is reflected in compensation.

Beyond pay, the role itself changes. You’re not just handing instruments — you’re treating patients.

What Are Tennessee’s Requirements to Become an EFDA?

These are Tennessee Board of Dentistry requirements. They are specific, sequential, and must be followed in order.

Step 1 — Become a Registered Dental Assistant (RDA) in Tennessee

Before pursuing any expanded function, you need to hold a current RDA status with the Tennessee Board of Dentistry. This is the starting point for the entire EFDA pathway.

If you’re starting from scratch with no dental background, your first goal is RDA licensure. This typically involves completing a dental assisting program, meeting board registration requirements, and gaining chair-side experience. Check tn.gov/health for current RDA licensure requirements before enrolling in any program.

Step 2 — Meet the experience requirement

For most expanded functions, Tennessee requires current RDA status before course enrollment. For restorative and prosthetic functions specifically, Tennessee requires at least two years of continuous full-time registered dental assisting employment in the three years before enrolling in a Board-approved course. This is a required eligibility threshold.

Step 3 — Complete Board-approved courses for each expanded function

Tennessee requires Registered Dental Assistants to complete board-approved certification and receive a Tennessee Board of Dentistry certificate before performing expanded functions. Depending on the function, this covers:

  • Coronal polishing

  • Sealant application

  • Nitrous oxide monitoring

  • Restorative and/or prosthetic functions

  • Dental radiography

These are Tennessee Board-issued certificates. Completing a DANB exam alone does not satisfy this requirement, though DANB credentials—particularly the Certified Dental Assistant (CDA) — are widely held among EFDAs and improve employability.

Step 4 — Pass written and clinical assessments

Each Board-approved course includes both written and clinical competency evaluations. You must pass both to receive your Board certificate.

Step 5 — Maintain current CPR/BLS certification

Basic Life Support certification must stay active throughout your career.

Always verify current requirements directly with the Tennessee Board of Dentistry at tn.gov/health and DANB’s Tennessee state requirements page at danb.org/state-requirements—requirements can and do update.

What Skills Does an EFDA Need?

EFDAs handle more complex duties than standard dental assistants. These skills matter most:

  • Attention to detail — Procedures like sealant application and coronal polishing leave no room for error. Precision directly affects patient outcomes.

  • Communication — You’re explaining procedures to patients and coordinating with the dental team simultaneously.

  • Infection control knowledge — EFDAs must know and follow current health and safety regulations at all times.

  • Multitasking — You’re managing patient care, instrument handling, and documentation in a fast-paced environment.

  • Anticipating the dentist’s needs — Experienced EFDAs work alongside the dentist, not behind them.

Tennessee’s experience requirement exists for good reason. These skills are built over years in the chair — not weeks in a classroom.

Where Can You Find EFDA Training Programs Near Germantown, TN?

Germantown sits in Shelby County, giving you access to dental assisting programs across the Memphis metro area. When evaluating any program, confirm it holds Tennessee Board of Dentistry approval. That approval is what makes your certificate valid in Tennessee.

Estimated timelines by starting point (these are estimates and will vary by program):

Starting Point

Estimated Timeline

No dental background

Obtain RDA licensure first—then meet experience threshold

Licensed RDA, under 2 years of experience

Complete experience requirements before enrolling in restorative courses

Licensed RDA with 2+ years of experience

4–12 weeks per expanded function course (estimate)

The experience requirement is the gate that most people don’t expect. Plan your timeline around it.

What Does an EFDA Do on a Typical Day in Germantown?

Here’s what a real shift looks like in a Germantown dental office.

You review the day’s schedule with the dentist. A patient comes in for a restorative procedure. The dentist preps the tooth. You place the restoration, shape it, and check the bite—a function that requires your restorative certification and the full experience threshold behind it. The dentist reviews your work before the patient leaves.

Between procedures, you’re applying sealants on a pediatric patient, performing coronal polishing, and updating records in the practice management system.

You’re not supporting care. You’re delivering it.

How Do You Find EFDA Jobs in Germantown, TN?

Once you’re certified, the job search is direct. Germantown has private practices, pediatric dental offices, and multi-location dental groups—many of which may hire for expanded function roles depending on practice needs.

When searching on MPM Dental:

  • Filter specifically by “EFDA” or “expanded functions”—general dental assistant listings won’t surface these roles

  • List your Tennessee Board certificates and RDA licensure clearly at the top of your resume

  • Name the specific expanded functions you’re certified for—sealants, coronal polishing, restorative functions, radiography

  • Target multi-location practices first—they hire more frequently and often provide structured onboarding for EFDAs

EFDAs often qualify for more competitive clinical roles because of their expanded scope and certifications. That distinction matters when you’re applying.

Conclusion: 3 Things to Remember

  1. Tennessee’s EFDA pathway is sequential and board-specific: RDA licensure first, then the experience threshold, then board-approved courses and certificates for each expanded function. Confirm current requirements at tn.gov/health before enrolling anywhere.

  2. The experience requirement is a required eligibility threshold: For restorative and prosthetic functions, two years of continuous full-time RDA employment is required before you can enroll. Plan your timeline accordingly.

  3. The EFDA role can significantly expand your scope, responsibilities, and earning potential: Advanced certifications and direct patient care set EFDAs apart from standard dental assistants at every stage of their careers.
