Title: Some Gum for Thought Hypothesis: Chewing Orbit gum prevents tooth decay by neutralizing acid in the mouth. Molecules: xylitol, carbonate, phosphate Chemical Principles: (bullet notes and a couple equations: sucrose, buffer) Data/Results: answers to six questions 1. What are the ingredients in wintermint orbit gum? A: sorbitol, gum base, glycerol, natural/artifical flavors, (less than 2%) hydrogenated starch, hydrolycate, aspartame, xylitol, acesulfamek, soy leathin, BHT, phenylalanine. 2. What’s in saliva and is it acidic? A: It contains mucus, proteins, salts, and enzymes ptyalin and maltase. Saliva functions as a buffer and is therefore not acidic. It is also 98% water. 3. What chemicals prevent and cause tooth decay? A: The bacteria Streptococcus mutans, along with other bacteria, causes tooth decay. The bacteria break down sucrose, creating lactic acid byproduct, demineralizing tooth enamel. Fluoride and xylitol are ingredients in tooth care products such as toothpaste and mouthwash that help protect your teeth. Fluoride inhibits demineralization of enamel. Xylitol is also claimed to help whiten teeth.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
