Introduction Sugar-free chewing gums are healthy alternative gums, it gives healthy effects on the salivary flow rate and acids (pH) in the mouth after a meal rather than gums that contain “unhealthy” sucrose. The sweetener that is used commonly to sugar-free chewing gum is Xylitol. It has been an essential healthy substitute that is also safe to use for children. 1In fact Xylitol has been approved by the Food and Drug Administration since the 1960’s (Shikhar Kumar, 2013) It can help to maintain the pH, decrease plaque in the mouth and can reduce oral microorganism. The correct pH in our mouth is important to keep our teeth healthy. The resting pH is around 6.5-6.9 which is slightly acidic. When we eat and drink the pH will go down causing our teeth to dissolve. In order to avoid this, we can use sugar-free gums which are excellent in pH neutralization. In this essay I will discuss the effects of sugar-free chewing gum on the pH in the mouth after a meal and also its oral benefits. I will also discuss its effects on our teeth in comparison to gums that contain unhealthy sucrose. The Benefits of Sugar-Free Chewing gums in the mouth All gums have the same benefits. The only thing that make them different from each other are the chemicals that are present in them which are sugars and sweeteners. 2Sugars and sweeteners have an important role to human diet (Mitchell, 2008).
