Listerine whitening mouth rinse is an amazing product. The entry of this product in to the market revolutionized the mouth hygiene concept. I have been using this product for more than five years. When I rinse my mouth using listerine whitening, I not only experience freshness in my breathe but also my teeth glitters. Its a must product for those who eat too much of onions and garlic. I carry this product where-ever I travel.
