From Stronger Gum, Extra Tough is a spearmint chewing gum sweetened with 100% xylitol. Xylitol is described as a natural sweetener that helps protect teeth from plaque build-up and tooth decay, making this a considered choice for those who prefer a sugar-free chew.
Used in Dr. Mike Mew’s clinic in craniofacial orthotropics, this Extra Tough version is presented as the hardest chewing gum on the market. It is also described as containing a higher dose of vitamin D3 and K2, with guidance focused on structured chewing routines.
Amount per piece: Total fat 0g (0%), sodium 0g (0%), protein 0g (0%), total carbohydrate 2g (1%), sugars 0g (0%), vitamin D3 6μg (30%), vitamin K2 25μg (21%).
Natural spearmint, gum base, xylitol.
Chew 1–3 pieces at a time, alternating sides to help keep exercise even across both sides of the jaw.
