Objectives: This study aimed to analyze the relationships among team intimacy, job satisfaction, resilience, and turnover intention among dental hygienists. Methods: Data were collected between May 2 and July 30, 2025, from clinical dental hygienists, with a final sample of 190 individuals. Results: Factors influencing the turnover intention of dental hygienists were significantly related to subjective health status (‘bad’ and ‘good’), work experience (9–17 years), age (≥40 years), and team intimacy, with an explanatory power of 35.5%. Conclusions: Dental hygienists should receive ongoing welfare programs and clinical training to develop their skills, strengthen workplace attachment, and enhance job competency. Active internal communication should also be promoted to foster emotional connections, mutual interest, and bonds among co-workers.
