Chewing sugarfree gum helps to promote remineralization of tooth enamel. The saliva stimulated by chewing gum helps strengthen the teeth and protect them against dental erosion through:
Diluting and clearing potentially erosive agents from the mouth
Buffering dietary acids
Maintaining a super-saturated state next to the tooth surface, due to the presence of calcium and phosphate from saliva

WOHP has supported independent clinical research into the benefits of chewing gum for more than 25 years.
Global health economic data suggests that increasing sugar-free gum consumption could reduce global dental expenditures from treating tooth decay by US$4.1 billion a year. Download Infographic (PDF) and Economic Benefits Study (PDF)
