People with hearing loss often encounter major difficulties obtaining oral-health guidance, which can affect their daily hygiene routines and dental status. This research set out to evaluate differences in oral-health knowledge and dental habits between Jordanian individuals with hearing impairment and those without it. A comparative cross-sectional design was used to survey 289 people, including 149 with hearing impairment and 140 without. A validated, researcher-developed questionnaire composed of closed-ended items was employed to measure oral-health awareness and self-care behaviors. Participants were selected through convenience sampling from facilities that serve individuals with hearing loss. Data analysis was carried out in SPSS® version 22, using P < 0.05 as the indicator of statistical significance. Group differences were explored using Chi-square tests and contingency tables. Those with hearing impairment exhibited noticeably weaker understanding of toothbrush-bristle firmness, recommended brushing frequency, the necessity of regular dental checkups, and symptoms associated with gingival disease (P < 0.05). A smaller share of this group reported brushing once or twice per day (82.8% vs. 93.3%, P < 0.001), and they were less likely to floss, use mouthwash, or choose fluoridated toothpaste (P < 0.05). They also consumed soft drinks more frequently (P < 0.001). The pronounced limitations in dental knowledge and hygiene practices among people with hearing impairments underscore the importance of tailored educational strategies. Approaches such as visually based materials, instructional videos, and specialized oral-health programs may improve everyday hygiene behavior, decrease oral-disease risk, and enhance their quality of life.
