口香糖又称胶姆糖,是一种清洁口腔的耐嚼性糖果,常嚼口香糖不仅能消除口臭,提神醒脑,促进唾液分泌有助消化功能,还能预防龋点和牙周炎。口香糖防龋主要使口腔 PH 值升高,在口香糖基胶中加偏碱性的药物例如柠檬酸钙、磷骏钙、磷酸铝等,亦可加上防龋药物如 NaF,但必须经过处理,涂上缓释剂,使其只能在口腔 PH 值8～9才能释放而在胃液中不释放。另一途径将易产酸的蔗糖、麦芽糖、果糖换成不易产酸的醣醇类如去氢麦芽糖,气化去氧蔗糖, Chewing gum, also known as chewing gum, is a chewing gum to clean the mouth, often chewing gum can not only eliminate bad breath, refreshing, and promote saliva secretion helps digestion, but also the prevention of caries and periodontitis. Chewing gum caries mainly to the oral PH value increased in the gum gum plus alkaline drugs such as calcium citrate, calcium Jun calcium, aluminum phosphate, etc., can also add anti-caries drugs such as NaF, but must be treated, Slow release agent coated so that it can only be released in the oral PH 8 to 9 and not in the gastric juice. Another way to acid-yielding sucrose, maltose, fructose is not easy to acid-producing sugar alcohols such as dehydrogen maltose, gasified deoxy sucrose,
