About WOHP

The Wrigley Oral Healthcare Program

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.
