Abstract: | This study tested a self‐determination theory (SDT) process model of oral health and subjective dental well‐being. The results showed that: (1) patients' perceptions of autonomy‐supportive dental professionals were significantly positively predictive of patients' psychological needs satisfaction in treatment; (2) needs satisfaction was significantly related to perceived dental competence (positive), autonomous motivation (positive), and controlled motivation (negative) for dental care; (3) perceived competence was significantly positively, and controlled motivation was significantly negatively associated with self‐rated oral health and oral‐health‐related quality of life; (4) autonomous motivation for dental treatment was significantly positively associated with valuing continued dental treatment; and (5) the three oral‐health‐related variables were all significantly positively linked to subjective dental well‐being. A structural equation model supported the SDT process model. |
