INTRODUCTION: Oral health is multi-faceted and influences a person's daily life, and numerous potential barriers and factors can challenge and pose barriers to good oral health. Shortages of healthcare professionals or incorrect care practices can be barriers to performing good oral healthcare. A knowledge gap has been identified in qualitative research on description of healthcare professionals' experiences of oral healthcare among older adults in municipal healthcare. AIM: To describe healthcare professionals' experiences of oral healthcare among older adults in Swedish municipal healthcare. DESIGN AND METHODS: The study employed a qualitative design guided by a secondary qualitative analysis method comprising inductive qualitative content analysis. Data were collected through semi-structured individual interviews with healthcare professionals. RESULTS: Good relationships and mutual trust create the conditions for delivering good oral healthcare. Knowledge provides confidence and trust in performing oral healthcare, experiences and strategies influence the individual adaptation of oral healthcare, and priorities and collaboration influence oral healthcare provision. CONCLUSION AND IMPLICATIONS: The performance of oral healthcare is complex and cannot be achieved without establishing a relationship with the older adult who needs care. Oral healthcare includes prerequisites such as routines, sufficient time, work-time planning, and collaboration between healthcare professionals. Registered nurses positively experience opportunities to collaborate with other healthcare professionals regarding oral healthcare and are seen as leaders in the Fundamentals of Care and are sharing good examples of oral healthcare in palliative care.
