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
