Red Flags When Choosing a Dentist: Warning Signs to Watch For

Finding the right dentist is about more than convenience or a friendly smile. Your oral health—and by extension, your overall health—depends on receiving quality dental care from a competent, ethical practitioner.

But how do you separate the excellent from the questionable? According to the National Practitioner Data Bank, there were nearly 2,500 reports of dental malpractice in the United States in 2023 alone. Many more instances of substandard care likely went unreported.

This guide will help you identify the dentist warning signs that should make you think twice before settling into that dental chair.

Credential and Reputation Red Flags

1. Difficulty Verifying Credentials

Every legitimate dentist should be properly licensed by their state’s dental board. If you can’t easily verify their credentials, that’s an immediate red flag.

How to check: Most state dental boards have online verification systems. For example, the American Dental Association provides links to all state dental boards where you can verify licensure and check for disciplinary actions.

Dr. Michael Roberts, a dental compliance expert, warns: “A dentist who can’t or won’t provide clear information about their education, licensing, or continuing education should raise immediate concerns.”

2. Concerning Online Reviews and Reputation

While a few negative reviews are normal for any business, patterns of complaints about specific issues deserve attention.

Watch for patterns like:

• Multiple complaints about unnecessary procedures
• Reports of unexpected pain or complications
• Mentions of billing issues or insurance fraud
• Comments about poor infection control

A study published in the Journal of Medical Internet Research found that online reviews of healthcare providers often highlight important quality indicators that formal metrics miss.

3. No Professional Affiliations

While not mandatory, membership in professional organizations like the American Dental Association (ADA) or Academy of General Dentistry (AGD) indicates a commitment to ethical standards and continuing education.

Communication and Transparency Warning Signs

1. Rushed or Inadequate Consultations

Quality dental care begins with thorough assessment and communication. According to Ask the Dentist, a new patient appointment should last at least 75-90 minutes to allow for proper examination and discussion.

Red flags include:

• Spending minimal time examining your mouth
• Not taking a complete health history
• Failing to ask about symptoms or concerns
• Rushing through explanations of findings

2. Unwillingness to Show and Explain X-rays

A trustworthy dentist will show you your X-rays and explain what they’re seeing. If your dentist takes X-rays but doesn’t share them with you or vaguely references “problems” without showing you the evidence, be wary.

Dr. Jennifer Thompson, a dental ethics educator, notes: “Patients have a right to see and understand their diagnostic images. A dentist who won’t share these is either hiding something or doesn’t respect patient autonomy.”

3. Lack of Treatment Options

Dental care rarely has only one possible approach. If your dentist presents only a single treatment option—especially an expensive one—without discussing alternatives, that’s concerning.

Questions to ask:

• “Are there other ways to address this problem?”
• “What happens if we do nothing right now?”
• “Is this treatment urgent or can it wait?”

4. Dismissive Attitude Toward Questions

A good dentist welcomes questions and takes time to answer them clearly. If your dentist seems annoyed by questions or gives dismissive, vague answers, consider it a warning sign.

Treatment and Practice Red Flags

1. Immediate Diagnosis of Multiple Problems

Be cautious if a new dentist immediately identifies numerous problems requiring extensive treatment, especially if your previous dentist never mentioned these issues.

According to the Coalition Against Insurance Fraud, some unethical dentists engage in “creative diagnosis”—finding problems that don’t exist or exaggerating minor issues to justify unnecessary procedures.

2. Pressure for Same-Day Procedures

Unless you’re in pain or have an emergency, major dental work shouldn’t be presented as needing immediate attention. Pressure to undergo non-emergency procedures the same day as diagnosis often indicates questionable motives.

3. Excessive X-rays or Tests

The American Dental Association provides guidelines on appropriate frequency for dental X-rays. For most adults with good oral health, bitewing X-rays are recommended every 18-36 months. Full-mouth X-rays are typically needed only every 3-5 years.

If your dentist wants to take full X-rays at every visit without clear justification, this could indicate unnecessary radiation exposure and potential billing fraud.

4. Outdated Equipment or Techniques

While the latest technology isn’t always necessary, extremely outdated equipment may compromise care quality. Modern dentistry has made significant advances in materials, techniques, and patient comfort.

Watch for:

• Film X-rays instead of digital
• Lack of proper sterilization equipment
• Visibly worn or outdated tools

5. Poor Infection Control Practices

Infection control is non-negotiable in dentistry. According to the Centers for Disease Control and Prevention, dental professionals should:

• Wear new gloves and masks for each patient
• Use sterile instruments
• Clean and disinfect surfaces between patients
• Follow strict handwashing protocols

If you notice staff not changing gloves between patients, unclean surroundings, or other hygiene issues, leave immediately.

Financial Red Flags

1. No Clear Fee Discussions

Transparent pricing is essential in healthcare. If your dentist can’t or won’t provide clear information about costs before treatment, proceed with caution.

2. Pressure to Finance Expensive Treatments

While payment plans can be helpful for necessary care, aggressive pushing of financing options—especially for cosmetic or elective procedures—may indicate a focus on profit over patient needs.

3. Insurance Manipulation

Some unethical dentists engage in questionable insurance practices. Be wary if your dentist:

• Offers to “work the system” to get insurance to pay
• Suggests billing for services not performed
• Recommends splitting treatments across calendar years to maximize insurance benefits without medical justification

Dr. Lisa Chen, a former dental insurance auditor, warns: “If a dentist suggests altering dates of service or procedure codes ‘to help with insurance,’ they’re likely committing fraud—and putting you at risk as well.”

4. Deals That Seem Too Good to Be True

Extremely low-priced services, particularly those advertised as “limited time offers,” often come with hidden costs or serve as bait for upselling more expensive treatments.

Ethical and Professional Conduct Warning Signs

1. Patient Shaming

A good dentist educates without shaming. If your dentist makes you feel embarrassed or guilty about your oral health, rather than offering constructive guidance, this indicates poor professional conduct.

2. Excessive Delegation to Assistants

While dental assistants and hygienists are vital team members, the dentist should personally handle diagnosis, treatment planning, and key procedures. If you rarely see the actual dentist, this could indicate assembly-line dentistry focused on volume over quality.

3. Resistance to Second Opinions

Any ethical healthcare provider respects a patient’s right to seek a second opinion. If your dentist seems offended or dismissive when you mention wanting another perspective, consider it a serious red flag.

4. Inappropriate Remarks or Behavior

Unprofessional comments, inappropriate jokes, or any behavior that makes you uncomfortable has no place in healthcare. Trust your instincts if something feels wrong in the dentist-patient interaction.

How to Protect Yourself

1. Research Before Your First Visit

• Check your state’s dental board website for license verification and disciplinary actions
• Read reviews across multiple platforms (Google, Yelp, Healthgrades)
• Ask friends, family, or coworkers for recommendations
• Verify professional credentials and affiliations

2. Trust Your Instincts During the Visit

• Does the office appear clean and professional?
• Is the staff friendly and willing to answer questions?
• Does the dentist take time to listen and explain?
• Do you feel respected and comfortable?

3. Get a Second Opinion When Necessary

According to the Journal of the American Dental Association, seeking a second opinion is particularly important when:

• Extensive treatment is recommended
• The diagnosis is unclear or concerning
• The proposed treatment is costly
• You feel uncomfortable with the initial recommendation

4. Know How to File a Complaint

If you encounter unethical or dangerous practices, reporting helps protect other patients. Complaints can typically be filed with:

• Your state’s dental board
• Your dental insurance provider
• The Better Business Bureau
• The American Dental Association (for ADA members)

The Bottom Line

Finding a trustworthy dentist takes effort, but your oral health is worth it. By recognizing these red flags early, you can avoid substandard care, unnecessary procedures, and potential harm.

Remember that most dentists are ethical professionals dedicated to patient care. These warning signs aren’t meant to make you suspicious of all dental providers but to help you distinguish excellent practitioners from those who fall short of professional standards.

Your relationship with your dentist should be built on trust, respect, and open communication. If something doesn’t feel right, it’s always appropriate to ask questions, seek clarification, or find another provider who better meets your needs.
