Caries and collaborations in context.

Dental caries is the most prevalent non-communicable disease globally and affects all age groups across the life course. Caries (and the dental cavities it produces) create very significant personal, societal and economic burdens across the world, despite dental cavities being largely preventable. This is why so many individuals and groups are collaborating to do something to improve the world landscape of avoidable cavities. Over the past 20 years, a series of international partnerships have been developed in caries research, education and management, which have paved the way for a shift towards collaborative, inter-disciplinary and multi-stakeholder approaches to caries. This paper: 1) discusses the motivation for individuals and organisations to collaborate towards 'service to society'/'making a difference'/'making the world a better place'; 2) explains that collaboration to make an impact is undeniably complicated, but highly desirable; 3) suggests that successful collaborations typically need to be sustainable and long-term; 4) provides some examples from the caries world of the range and depth of collaborations making a difference; and 5) suggests that we now seem to be at multiple 'tipping points' to accelerate the progress of integration, intersectoral and interprofessional collaboration and of aligning caries control with the broader context of oral health and general health globally.
