Tooth decay is caused by certain bacteria rapidly consuming sugars that are placed in your mouth. These bacteria produce acid within a very short time after exposure to sugars. Repeated acid production eventually dissolves enough tooth structure to cause tooth decay, also known as a cavity. Exposed root surfaces of teeth, which are not covered by enamel, are less able to withstand repeated acid attacks and therefore decay more readily.
Over 25 years of clinical testing confirms that xylitol is the best sweetener for teeth. Frequent eating of foods high in sugars and starches can promote tooth decay. Xylitol, unlike other sugars, may reduce the risk of dental caries. Sugar free chewing gums and candies made with this sweetener have already received official endorsements from six national dental associations.
