OH MY GUM! is chewing gum as it should be : natural, plant-based, plastic-free and sugar-free. Taking chewing gum back to its plant-based roots in style, OH MY GUM! is made with sustainably harvested tree sap called chicle - what chewing gum was originally made of. OH MY GUM! in all natural mint is sugar-free and sweetened with 100% plant-based and tooth-friendly xylitol.
