Saliva is a key area within oral care research, and many researchers are making new explorations and advances that will help pave the way forward.
Independent research supported by Wrigley funding has continued to have an impact on the oral care arena for nearly 80 years. Through a fellowship with Northwestern University in the United States in the 1930s, researchers discovered the dental health benefits of chewing sugarfree gum and continued to explore that relationship in the following decades. In the 1980s, groundbreaking research proved that chewing sugarfree gum helps stimulate saliva production, a key element in reducing harmful plaque acids. In the 1990s Wrigley also supported research that validated the role sugarfree chewing gum can play in caries reduction. In recent years the FDI World Dental Federation and more than 25 national dental associations have recognized the strength of the scientific evidence which supports chewing sugarfree gum, and the FDI has granted the use of its logo on Wrigley packs. And in 2009, the European Food Safety Authority (EFSA) approved claims that sugarfree chewing gum can help neutralize plaque acids, remineralize tooth enamel and reduce oral dryness.
Research shows that chewing sugarfree gum can help protect teeth in a number of ways:
