Chewing gum, it is said, exercises the facial and jaw and muscles and improves the blood circulation in those parts; that’s why many prefer this particular facial exercise to ward off wrinkles. One study has shown that chewing gum stimulates saliva production and increases the salivary flow, which in turn neutralises teeth-eroding and cavity-causing acid produced by harmful bacteria present in the teeth. One more study from
has concluded that there is a considerable reduction in tooth-decay in children who chewed gum with an artificial sweetener called Xylithol. However gums containing sugars and other artificial sweeteners can cause cavities and tooth-decay, especially if you don’t rinse your mouth after chewing. So better use a sugarless gum for chewing. A recent study conducted by Andrew Scholey from Finland has shown that chewing gum can relieve anxiety, improve alertness and reduce stress among individuals. Even the Swinburne University, Australia armed forces have been providing troops with caffeinated gum to keep soldiers alert for extended periods of time without experiencing fatigue or drowsiness. This practice was started as early as 1935 (World war-I days) and is continued even today. Chewing gum for long hours can also induce a headache as so many muscles in your face and jaw and are at work and keeping this up repeatedly for hours on end can bring on jaw-pain or a headache. Orthodontists say that if your head hurts or if you often experience jaw-muscle fatigue after chewing gum, it is better to stop this habit for sometime at least. And by chance if chewing gum gets stuck in your hair or on your shoes, rub hard on it with an ice-cube. It will come off easily in a few minutes. U.S.
