Objective:
Dentine hypersensitivity (DH) affects approximately one in three dentate adults yet remains poorly managed. This study aimed to generate a comprehensive, patient-centred account of how Australian adults experience, self-manage, and seek care for DH, and to identify system-level barriers to adequate management.
Materials And Methods:
Eighteen Australian adults aged 26-67 years with clinically confirmed DH completed individual semi-structured interviews via Zoom, conducted by a single trained qualitative oral health researcher (N.T.), and analysed using Thematic Framework Analysis. Independent dual coding of a 22% subsample yielded Cohen's kappa = 0.83. Reporting followed the SRQR checklist.
Results:
Six themes were identified, covering DH sensation, dietary adaptation, emotional responses, self-management strategies, financial burden, and interactions with the dental system. Seventeen of 18 participants reported dietary or behavioural modifications, yet nine simultaneously described DH as having no daily impact, a contradiction suggesting response shift: participants had gradually adjusted to long-standing restrictions and no longer noticed them as limitations. Desensitising toothpaste was used by 89% through self-initiation; no participant received proactive DH screening; and three independently discovered evidence-based leave-on application without clinical instruction. Financial barriers converted a treatable condition into irreversible tooth loss through cost-driven extractions.
Conclusions:
DH imposes a chronic, complex burden systematically underestimated by patients and clinicians alike. Proactive screening, structured communication, and equitable access to professional care are required to close the gap between guideline-recommended and actual management.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
