A career as a dental assistant can be highly rewarding. It offers a unique blend of patient care, technical skills, and interpersonal interaction. Whether you’re assisting in a dental procedure, comforting a nervous patient, or managing administrative tasks, dental assistants are key members of any dental practice.

But while the profession is accessible and offers a clear career trajectory, there are certain factors that could disqualify you from pursuing this path. If you’re considering becoming a dental assistant—or are already on this path—it’s important to understand these potential hurdles so you can prepare and act accordingly.

This blog will walk you through what disqualifies someone from becoming a dental assistant—covering everything from criminal records to unsatisfactory health screenings. By the end, you’ll have a clear understanding of what’s required and how to overcome challenges, if any arise.

What Does a Dental Assistant Do?

Before we discuss disqualifications, it’s helpful to understand the key responsibilities of a dental assistant. Dental assistants work alongside dentists and other oral healthcare professionals, providing support in clinical and administrative tasks. Responsibilities might include:

• Sterilizing instruments and preparing exam rooms
• Assisting dentists during procedures
• Directing patients and providing post-procedure care instructions
• Managing office tasks, such as scheduling and billing
• Educating patients on proper oral health practices

The role requires both technical skills and professionalism, and for that reason, employers and licensing bodies set certain eligibility criteria. Below, we’ll review the most common hurdles people face when entering this field.

1. Criminal History

Criminal Convictions and Licensure

One of the most significant barriers to becoming a dental assistant is a criminal history—particularly convictions related to theft, drug-related offenses, or violent crimes. Many states require dental assistants to undergo background checks as part of obtaining licensure or certification.

Regulatory agencies may reject applications from those with certain criminal convictions, especially if the crime suggests a lack of trustworthiness or professionalism needed for the role.

Can You Work as a Dental Assistant With a Criminal Record?

It depends. Some convictions, such as misdemeanors or older, nonviolent offenses, might not immediately disqualify you. Additionally, if a conviction has been expunged from your record, you may still be eligible for licensure. It’s always a good idea to check with your state’s dental board for specific regulations.

2. Failing a Background Check

Many employers and licensing bodies require background checks to determine eligibility. Beyond criminal history, a failed background check may also uncover other disqualifying factors such as:

• Misrepresentation of qualifications
• Financial liabilities, such as unresolved tax liens
• Previous disciplinary actions in similar fields

Ensure all information on your application or resume is truthful and accurate to minimize risks.

3. Drug and Substance Abuse

The healthcare field requires professionals who are reliable and in control. A history of substance abuse can disqualify an individual due to concerns over workplace safety and patient care risks. Here’s what to know:

• Drug Testing: Most dental assistant jobs require passing a pre-employment drug test. Evidence of drug use may lead to disqualification.
• Substance Abuse History: If you've struggled with addiction but have sought treatment and successfully recovered, certain programs may still consider you eligible. Many employers appreciate honesty and evidence of rehabilitation.

4. Lack of Required Education or Certification

To work as a certified dental assistant (CDA) in most states, you must complete an accredited training program and pass examinations. Without these requirements, it’s likely you’ll face disqualification.

What Are the Minimum Education Requirements?

• A high school diploma or GED equivalent is typically the starting educational requirement.
• Further, most states require completion of a dental assisting training program accredited by the Commission on Dental Accreditation (CODA). These programs provide the clinical and theoretical knowledge required for the role.

Certification Requirements

Some job roles require additional certifications such as:

• Passing the Dental Assisting National Board (DANB) exam to earn a CDA credential.
• Earning radiation health and safety (RHS) or infection control (ICE) certifications.

Without these certifications, employment and licensing may be extremely limited.

5. Physical and Mental Health Standards

Physical Health Requirements

Dental assisting is a physically demanding job. You’ll often need to:

• Stand for long periods during procedures
• Have good manual dexterity to handle tools
• Lift equipment or move patients when necessary

If you have a medical condition that limits your ability to meet these demands, it may impact your eligibility.

Mental Health and Cognitive Capacity

Dental assistants must possess strong attention to detail, multitasking skills, and a calm demeanor when working under pressure. Severe cognitive impairments or unmanaged mental health issues that affect these abilities could serve as disqualifications. It’s important to discuss your fitness for the role with your healthcare provider if you have concerns.

6. Ethical Standards and Professional Misconduct

Past professional misconduct, such as violating ethical guidelines in a previous healthcare-related role, could prevent you from being hired or licensed. Dental assistants are trusted to maintain high ethical standards, particularly when handling patient records or administering care.

Examples of professional misconduct that may disqualify you include:

• Fraud or theft in a healthcare setting
• Breach of patient confidentiality
• Submitting falsified certifications or credentials

Maintaining a clear professional record is critical for long-term success in any healthcare field.

7. Failing to Maintain Certification or Continuing Education

Dental assisting isn’t a "set it and forget it" type of career. Many states have ongoing requirements for maintaining certification or licensure. For example, you may need to:

• Complete a certain number of continuing education (CE) credits annually
• Renew your CPR certification regularly
• Participate in hands-on skill refreshers

Failing to meet these requirements can lead to disqualification from practicing, even if you were initially licensed without issue.

What to Do if You Face a Disqualification

If any of these factors apply to you, don’t give up hope! Here are strategies to overcome common disqualifications:

• Expunge Criminal Records: Work with an attorney to clear certain records if legally eligible.
• Pursue Rehabilitation: Evidence of completed rehab programs can improve your standing, especially regarding substance abuse issues.
• Meet Continuing Education Requirements: Enroll in accredited courses to meet certification requirements.
• Be Transparent: Employers and licensing bodies appreciate honesty and a willingness to address past mistakes.

The dental field is always looking for dedicated professionals, and showing a commitment to growth can make all the difference.

Set Yourself Up for Success as a Dental Assistant

Becoming a dental assistant is a meaningful and achievable career for many healthcare professionals. While there are factors that could disqualify you, being informed and proactive can help you overcome potential obstacles.

If becoming a dental assistant is your passion, focus on building a strong foundation through education, certifications, and ethical practice. Pathways to correct past mistakes are available, so use them to your advantage.
