To see where breakthroughs in sugar-free gums are born, look to the labs of Trident®. Only Trident Xtra Care® with Recaldent® promotes remineralization to strengthen and rebuild tooth enamel. Recaldent, also known as CPP-ACP, remains in the plaque layer for up to 3 hours after chewing. Trident White® and Trident sugar-free gums with xylitol provide advanced protection too. Just more proof why Trident is an innovative leader in sugar-free gum.
