Close up is the first gel toothpaste in the world. I am using this paste twice a day since my childhood days and a big thumbs-up to the manufacture. This toothpaste not only cleans our teeth but also helps us to get fresh breath upto 12 hours. This paste contains zinc sulphate, metal salt and anti bacterial properties. It kills the bacteria and freshen up our breathe. My mouth remains fresh for all day after brushing my teeth in the morning. I feel confident in talking to others as I have no bad smells. My teeth are strong and away from germs. I like its taste as well. the packaging of the tube is also very attractive. I am so addicted to this paste that I have never tried any other paste. I will definitely recommend this tooth paste to everyone.
