Abstract
A gum of 5-20 wt. % polyisobutylene, 20-70 wt. % filler and 10-50 wt. % microcrystalline wax with optionally a flavorant and/or a sweetener, is flexible and soft enough to withstand repeated severe flexing yet can take and retain a dental impression after a single bite. The gum is free of crystallizable ingredients such as bulk sweeteners and therefore exhibits outstanding storage stability.
