Fluoride toothpaste is the only proven way to prevent tooth decay. Darlie Double Action Fluoride Toothpaste is one of the best dental care products. Fluoride is a natural mineral found in most water sources such as lakes, rivers, and the ocean. Over the past 70 years, fluoride has been added to most water supplies in various countries. When added to toothpaste and dental products, this mineral helps prevent tooth decay by strengthening the enamel or hard surface of the tooth. Studies have shown that the presence of fluoride in public water supplies prevented tooth decay in children and adults by at least 25 percent. The fluoride in toothpaste is not only safe but also a natural ingredient. Fluoride is a natural element, a natural void fighter. Certain fluoride compounds that have been shown to be effective in preventing tooth decay and are approved by the US Food and Drug Administration (FDA) for preventing tooth decay are added to toothpaste. However, fluoride-free toothpastes are touted as safer and more effective ways to keep your teeth healthy. No other ingredient can match fluoride. Volume: 2 tubes of 170 grams. Tags: Thai, toothpaste
