How Poor Oral Health Affects Self-Esteem and Confidence at Work

Written by: Dion Kramer | Founder & Chief Executive Officer | LinkedIn

Employee wellbeing has become a critical business priority as organisations recognise the cost of unmanaged health issues at work. Workplace mental health and personal stressors are rising.

Oral health plays an important role in how people feel about themselves.

Poor oral hygiene and dental health problems can affect confidence and self-esteem. Issues such as bad breath, tooth decay, or missing teeth may make people feel embarrassed in social or workplace situations.

Recent research shows that oral health plays an important role in emotional and social well-being.

In Australia, more than 2 in 3 adults delayed or avoided dental care due to cost, according to the Australian Dental Association (ADA), which can allow oral health problems to worsen over time.

How Does Poor Oral Health Affect Self-Esteem?

The mouth sits at the centre of how we express ourselves. We use it to speak, laugh, eat and connect. When oral disease damages appearance or function, people become acutely self-conscious about it.

Good dental health is not just physical. It is deeply tied to identity. When oral hygiene deteriorates and disease sets in, the psychological fallout is well-documented — and often underestimated by employers.

Signs of Low Self-Esteem Linked to Poor Oral Health

Poor oral health can affect how people feel and behave. These are the most common signs of low self-esteem and lack of confidence at work linked to dental health.

• Avoiding Smiling: People with dental issues may hide their teeth when they smile. In Australia, over 33% of adults report feeling uncomfortable about the appearance of their teeth or mouth.
• Covering the Mouth While Speaking: Some people cover their mouth when talking or laughing. This often happens when someone feels self-conscious about bad breath, missing teeth, or visible cavities.
• Avoiding Social Situations: People with poor oral health may avoid social gatherings or photos. Dental problems can affect appearance and speech, which may reduce confidence and participation in social or workplace activities.
• Reduced Confidence at Work: Poor oral health can make people feel less confident when speaking in meetings or presentations. Oral hygiene directly affects confidence at work — how comfortable people feel when interacting with colleagues, clients and leadership.
• Increased Anxiety About Dental Care: Fear or anxiety about dental visits can worsen oral health problems. Around 16% of Australian adults experience dental fear or anxiety, which can delay treatment and allow issues to worsen.
• Lower Overall Well-Being: Nearly 60% of how good an employee feels about their life overall comes down to one thing - how confident they feel about their smile.
• Mental Health Concerns or Depression: The relationship between dental health and mental health is well-established. Dental pain, tooth loss, and visible oral conditions may increase psychological stress and emotional distress. Research shows that poor oral health is associated with a higher risk of depression and reduced quality of life.

The Cost Trap: Why Australians Are Skipping the Dentist

Australia spent $12.5 billion on dental services in 2022–23. Yet access remains deeply inequitable. Individuals fund 61% of all dental expenditure — a proportion that has barely shifted in a decade.

Dental care sits entirely outside Medicare. Unless you qualify for a concession card or a narrow public program, you pay in full.

The cost barrier hits hardest among working-age adults — the people driving Australian business.

The pattern is stark. When people cannot afford treatment, they defer.

Deferral becomes neglect. Neglect becomes disease. Disease erodes appearance, confidence — and self-esteem.

How Poor Oral Health Causes a Lack of Confidence at Work

Most people spend the majority of their waking hours at work. Confidence at work translates directly into output.

When an employee avoids speaking up in meetings because they are embarrassed about their teeth, that is not a personal quirk. It is a business problem.

Dental pain is a significant driver of anxiety and depression. Chronic oral pain from untreated cavities, gum disease and temporomandibular disorders increases stress hormones and disrupts sleep.

Employees managing untreated dental problems carry a hidden burden into every working day.

Public health research notes that poor oral hygiene and its impact on confidence at work shows up as social withdrawal, diminished self-esteem and psychological distress.

These are not abstract feelings — they manifest as less collaboration, lower engagement and reduced discretionary effort.

Why Addressing Poor Oral Health Improves Self-Esteem and Confidence

Improving oral health can significantly boost self-esteem and confidence. Research shows that better dental health is closely linked to improved well-being and social comfort.

1. People With Healthy Smiles Report Higher Confidence

Studies in America show that 93% of people who are satisfied with their smile rate their self-confidence as excellent or very good. In contrast, confidence levels drop significantly among people who feel unhappy about their teeth.

2. Satisfaction With Oral Hygiene Drives Confidence at Work

Studies show that satisfaction with dental appearance is strongly linked to higher self-esteem and social confidence. People who feel happy with their smile tend to report better psychosocial well-being and more positive self-perception.

3. Good Oral Health Improves Quality of Life

Oral health research shows that dental health strongly influences oral-health-related quality of life, including social comfort, emotional well-being, and daily functioning.

4. Preventive Care Can Improve Oral Health Outcomes

Oral health promotion programs have shown measurable improvements. A recent global study found the proportion of people with healthy mouths increased from 29.8% to 67.8% after oral health interventions, highlighting the benefits of preventive care.

5. Confidence Improves When Dental Problems Are Treated

Studies on dental aesthetics show that over 90% of people report satisfaction with their smile when dental health issues are addressed, which supports stronger self-confidence and social comfort.

Maintaining good oral hygiene and dental health helps people feel more comfortable smiling, speaking and interacting with others. Over time, this improves both confidence and self-esteem.

What Can Employers Do to Support Oral Hygiene and Confidence at Work?

Employers play an important role in supporting employee well-being. Improving access to dental care helps employees maintain better oral health, confidence and overall mental well-being.

Here are some ways organisations can help:

1. Offer Employer-Paid Dental Cover

Providing dental cover as part of employee benefits makes preventive care more accessible. Research shows that when dental cover is employer-paid and easy to access, Australians are 186% more likely to attend regular dental check-ups.

Regular check-ups help detect dental problems early and reduce the risk of serious oral health issues.

2. Reduce Absenteeism and Presenteeism

Untreated dental problems cause pain, fatigue and difficulty concentrating at work. Dental-related absenteeism costs businesses around $1.3 billion each year, while presenteeism results in about $7.4 billion in lost productivity annually. Improving access to preventive dental care directly reduces both.

3. Include Dental Cover to Complement Employee Assistance Programs (EAP)

EAPs are a valuable part of any employee well-being strategy — but they are largely reactive. Employees tend to access them when a problem has already taken hold. Dental cover works differently.

It is proactive. It keeps people out of the pain-shame-avoidance cycle before it starts. Together, EAPs and dental cover address mental health from both ends: one responds when employees are struggling; the other removes a key trigger of that struggle in the first place.

For organisations serious about the link between dental health and mental health, offering both sends a clear message — we support your wellbeing before it becomes a crisis.

4. Support Employee Well-Being

Oral hygiene and confidence at work are deeply connected. By offering accessible dental care, employers show they support employees as whole people — not just their productivity.

This improves satisfaction, workplace engagement and overall well-being.

Case Study: Costco Strengthens Workforce Participation Through Employer-Paid Dental Cover

Costco funds dental cover for full-time and part-time employees, extending access to workforce segments that retail traditionally excludes. By removing cost as a barrier to preventive dental care, Costco neutralises a key driver of pain, embarrassment, and withdrawal at work.

The outcome is well-documented: Costco's annual employee turnover sits at around 8%, against a 60% retail-industry average, according to research from MIT's Professor Zeynep Ton and cited by Harvard Business School.

Conclusion

How poor oral health affects self-esteem is no longer just a question for dentists. It is a question for employers. Oral health affects more than physical well-being — it influences self-esteem, confidence and social interactions.

Poor oral health and self-esteem are deeply linked: when one deteriorates, so does the other. Signs of low self-esteem and a lack of confidence at work often trace back to untreated dental conditions.

By providing employer-paid dental cover, employers are supporting access to dental care and preventive check-ups, to help employees and their families maintain better oral health, confidence, and overall well-being, creating healthier and more productive workplaces.
