Xylitol gum or mints used three to five times per day (for a total intake of 5 grams) is considered ideal. Frequency and duration of exposure is important, therefore it is important for gum to be chewed for approximately 5 minutes and mints to be allowed to dissolve slowly. Using xylitol immediately after meals and snacks to help reduce plaque and inhibit adhesion of bacteria to teeth, and to reduce the contact time of sugar is what dentists recommend. Human consumption of xylitol has been confirmed for safety. Pet owner should note, however, that xylitol is harmful to dogs.

Products containing xylitol have been around for years, but only recently have they become mainstream. Xylitol can be found in chewing gum, toothpastes, mouthwashes and other oral care products, candies, and some pharmaceuticals. On food labels, xylitol is classified broadly as a carbohydrate and more narrowly as a polyol.
