When people think about WorkCover claims in NSW, physical injuries tend to come to mind first. But psychological injury at work is increasingly recognised as a legitimate and significant category of workplace injury, and its effects on the body extend well beyond mental health.
One area that often goes unnoticed is the impact of work-related stress on dental health. From teeth grinding to jaw pain and gum problems, the physical symptoms of work-related stress can show up in the mouth in ways that are both painful and costly to treat.
For some patients, a WorkCover dental claim may be a legitimate option worth exploring.
How Work-Related Stress Affects the Body
Chronic stress triggers a sustained physiological response in the body. Stress hormones like cortisol increase inflammation, suppress the immune system, and affect how the body heals. Over time, these effects can show up throughout the body, including in the mouth.
According to healthdirect.gov.au, prolonged stress can affect physical health in multiple ways, including disrupting sleep, increasing inflammation, and lowering the body’s ability to fight infection. All of these factors have direct implications for oral health, as well.
The Dental Effects of Workplace Stress
Teeth Grinding (Bruxism)
One of the most common physical symptoms of work-related stress is bruxism, the clenching or grinding of teeth, often during sleep. Many people are unaware they grind their teeth until a dentist identifies the signs: worn enamel, flattened tooth surfaces, cracked teeth, or jaw soreness upon waking.
Bruxism caused by workplace stress can cause significant dental damage over time. When it is left unaddressed, it can lead to cracked or broken teeth that may require crowns or fillings, and in severe cases, tooth loss.
A custom night guard is one of the most effective ways to protect the teeth while the underlying stress is being managed.
Temporomandibular Disorder (TMD)
Work stress jaw clenching is closely linked to temporomandibular disorder, a condition affecting the jaw joint and surrounding muscles. Symptoms include jaw pain, clicking or popping sounds when opening the mouth, headaches, and difficulty chewing.
TMD can develop gradually as a result of sustained clenching and tension in the jaw muscles, often triggered by long hours at a desk or high-pressure work environments.
Gum Disease
Stress suppresses the immune system, making the gums more vulnerable to bacterial infection and inflammation. Research has identified psychological stress as a risk factor for periodontal (gum) disease.
Patients experiencing chronic workplace stress may find that gum problems worsen or become harder to manage, even with good oral hygiene at home.

Dry Mouth and Increased Decay Risk
Stress affects saliva production, and some medications used to manage anxiety or depression can cause dry mouth as a side effect. Reduced saliva flow means less natural protection against bacteria, which can accelerate tooth decay and increase the risk of cavities.
Neglected Oral Hygiene
When someone is experiencing psychological injury at work, whether burnout, anxiety, or workplace trauma, daily self-care routines often suffer. Skipping brushing, avoiding dental appointments, and changes in diet can all compound existing oral health issues, turning minor problems into more significant ones.
Can You Make a WorkCover Dental Claim for Stress-Related Dental Damage?
This is a question we hear, and the honest answer is: it depends.
NSW workers’ compensation law allows for psychological injury claims where employment was a significant contributing factor to the condition. However, whether stress-related dental damage could be covered as part of that claim is a separate and more complex question.
It depends on the specifics of your case, the nature of the accepted injury, and how the dental damage is clinically documented.
It is also worth noting that NSW workers compensation laws changed in March 2026, introducing a higher threshold for how psychological injury claims are assessed. This makes it even more important to get current, personalised advice rather than relying on general information.
If you think your dental health has been affected by a psychological injury at work, the right first step is to speak with your treating doctor and a qualified workers compensation legal adviser. They can assess whether your situation may qualify and guide you through the process.
