Zollipops are not ordinary lollipops. Zollipops are supercharged with Xylitol, Erythritol, Stevia and other smile friendly natural ingredients. Zollipops are the “After You Eat Treat”. Enjoy one after every meal or sugary snack. How do Zollipops work? Take the ZPh challenge to find out. Test the pH in your mouth before and after a Zollipops, and see the pH change. Why do we care about pH? pH is a key factor in oral health. We all remember experiments early on as children when one of our baby teeth was left in a glass of soda overnight and simply disappeared. The tooth, being made up of calcium, dissolves as acid breaks down the calcium until the pH is neutral. Zollipops helps restore a healthy pH in your mouth and may reduce the risk of tooth decay, dental caries and future development of cavities.ExpirationThis product has no expiration date or the manufacturer has not provided an expiration date.
