The Wrigley Oral Healthcare Program (WOHP) partners with dental professionals worldwide, helping them improve their patients’ oral health through one additional simple and enjoyable step in their daily routine: chewing sugar-free gum after eating and drinking on-the-go.

We support:

  • Independent clinical research into preventive dentistry
  • Funding for local dental associations and governments
  • Conferences and continuing professional development programs associations
  • Development of education materials for patients, teachers and families

WOHP is one example of how we make a difference to people and the planet through performance, and how we incorporate our principles based approach to business into all that we do.
