Xylitol is a natural sweetener that helps prevent tooth decay. Xylitol is found in fruits and vegetable like plums, raspberries, strawberries and lettuce. Also, xylitol is produced in the human body during the breakdown of glucose (blood sugar). Xylitol is as sweet as sugar, but contains 2.4 calories/gram where sucrose (table sugar) contains 4 calories/ gram; Xylitol has 40% fewer calories than sucrose.
Xylitol doesn’t cause cavities because it doesn’t produce acids (ferment) in the mouth. The bacteria that cause cavities, Streptococcus mutans, cannot digest Xylitol therefore, there is a reduction in the number of S.mutans in the plaque and ultimately in the mouth. Also, the plaque is less sticky and can’t adhere to tooth surfaces as easily.
In order to reap its benefits, Xylitol must be ingested frequently. Chewing gum is an effective means of getting Xylitol. Gum, of course, can pull food particles from the teeth and the ingredient Xylitol can reduce the number of bacteria in the mouth. Gum can relieve dry mouth by stimulating the flow of saliva. People suffering from dry mouth are more likely to experience tooth decay and gum infections.
Marilynn Rothen, RDH, B.S., (in Dimensions of Dental Hygiene, Oct 2005 issue) recommends 6-10 g of Xylitol/ day via chewing gum. To achieve maximum effectiveness, chew the Xylitol gum 3-4 times per day for 5 minutes to get all of the Xylitol out of the gum and into the mouth.
Good oral hygiene includes tooth brushing twice a day and proper flossing daily.
Fluoride rinses will help prevent cavities. Listerine rinses will help prevent gum infections. Now, more recently, the news is that good oral health is also promoted by chewing gum containing Xylitol. Good tasting and good for you!
