Behavioral Adaptations to Dentine Hypersensitivity: A Qualitative Examination

Toothbrush abrasion, tooth whitening, periodontitis, and certain restorative and periodontal procedures are some potential causes of dentine hypersensitivity (DH) which can affect between 4 and 57 percent of the population. While many studies of DH rely partially on patient reports of pain, no study has examined qualitatively the subjective experience of DH from individuals suffering from the condition. Objective: The goal of this qualitative study was to examine behavioral adaptations used to avoid and mitigate the pain associated with DH. Methods: The current study involved individual interviews and focus groups to elicit information from twenty-six (mean age = 31.7, s.d .= 11.4, 85% female) participants identified as having at least three clinically qualified teeth with DH. Prior to the interviews and focus groups, participants completed a stimulation phase in which cold and room-temperature water was placed on teeth previously identified as sensitive due to cervical erosion, abrasion, and/or gingival recession. Participants were then asked to describe what behavioral modifications they make to avoid or lessen the pain of DH. Interviews and focus groups were recorded and transcribed, and the transcripts analyzed for themes. Results: Common triggers noted were cold foods and beverages, sweet foods, cold air, citrus fruits and juices, and foods containing vinegar. The most common behavioral adaptations included avoiding drinking beverages with ice, drinking with straws, chewing with non-sensitive teeth, eating smaller portions of cold foods, and pursuing desensitizing agents, either over-the-counter or through dental professionals. Behavioral adaptations were mentioned more frequently than therapeutic treatment options. Conclusions: Individuals with DH in this sample reported using behavioral adaptations more often than clinical treatment options to manage the pain associated with DH. Many dental patients may choose to adapt to DH and use over-the-counter products rather than seek professional treatment for this condition. This study was supported by GlaxoSmithKline.
