The prevalence and impact of dental anxiety in Australia
High dental fear has been described as one of the most prevalent anxiety conditions in Australia.
Dental anxiety is one of the most common yet under-recognised barriers to oral healthcare in Australia. Research consistently shows that a substantial proportion of the population experiences some level of fear related to dental treatment, with a significant minority experiencing severe anxiety or phobia.
Large population-based studies indicate that approximately 16% of Australian adults experience high dental fear, equating to roughly one in six people . This finding has been replicated across multiple studies, with prevalence estimates for high dental fear generally ranging from 7.8% to 18.8%, depending on the measurement tools used. More severe forms, classified as dental phobia, affect approximately 5% of the population, representing a group whose fear significantly impacts daily life and healthcare access .
At a broader level, anxiety related to dental care exists on a spectrum. Surveys suggest that a much larger proportion of Australians experience some degree of dental anxiety, even if it does not meet the threshold for phobia. This highlights that dental anxiety is not a niche issue, but a widespread public health concern.
Importantly, dental anxiety is not evenly distributed across the population. Higher levels are consistently observed in:
Women compared to men
Middle-aged adults
Individuals from lower socioeconomic backgrounds
Those with irregular or episodic dental attendance
These patterns suggest that dental anxiety both contributes to, and is reinforced by, inequalities in access to care.
National data shows that around 28% of Australian adults delay or avoid dental care when needed, with fear being a contributing factor alongside cost and access.
The impact on oral health and healthcare utilisation
The most significant consequence of dental anxiety is avoidance of dental care. Patients with high dental fear are more likely to delay or avoid appointments, often only attending when symptoms become severe. This creates what has been described as a “vicious cycle” of dental fear — where avoidance leads to worsening oral health, which in turn increases the likelihood of more invasive and anxiety-provoking treatment .
At a population level, this has measurable effects. National data shows that around 28% of Australian adults delay or avoid dental care when needed, with fear being a contributing factor alongside cost and access . Individuals with high dental anxiety are more likely to present with:
Increased dental decay
Missing teeth
Poorer periodontal health
Greater need for emergency or complex treatment
This pattern not only affects individual patients but places additional strain on the healthcare system through preventable disease and more resource-intensive care.
Broader psychological and social impacts
The impact of dental anxiety extends beyond oral health. It is increasingly recognised as a significant psychological and quality-of-life issue.
High dental fear has been described as one of the most prevalent anxiety conditions in Australia, affecting approximately one in seven adults . It is associated with:
Increased general anxiety and distress
Reduced confidence and self-esteem
Social avoidance (e.g. embarrassment about dental appearance)
Impaired eating, speaking, and overall wellbeing
Oral health itself plays a key role in social and psychological functioning. Around one-third of Australian adults report discomfort about their dental appearance, which can influence social participation and mental health .
Implications for dental practice
The high prevalence and wide-ranging impact of dental anxiety highlight that it is not an isolated issue, but a core component of everyday dental practice. For clinicians, this means that managing dental anxiety is not just about improving patient comfort — it is essential for:
Improving attendance and engagement
Reducing disease burden
Enhancing treatment outcomes
Supporting long-term oral health
A fear-aware, patient-centred approach is therefore not optional, but fundamental to effective care delivery.
