This dataset contains anonymized responses from 421 Thai older adults who participated in a cross-sectional study on ageing perception, oral health status, and oral health-related quality of life (OHRQoL). Data were collected using validated instruments, including the Thai version of the Attitudes to Ageing Questionnaire (AAQ-SF) and the Oral Health Impact Profile (OHIP-14). The dataset includes socio-demographic variables, clinical oral health measures, and total and subscale scores for ageing perception and OHRQoL. This dataset was prepared to support transparency and reproducibility in line with PLOS ONE’s data sharing policy.
