Fluoride is a very important mineral for a person’s health in preventing tooth decay. Over 95% of toothpastes sold in the U.S. contain fluoride. Most of which, have between 1,100 ppm and 1450 ppm. Ingesting too much fluoride can lead to dental fluorosis, which defects and weakens tooth enamel. The risk for dental fluorosis is much higher in children when teeth are developing. Ion chromatography was used to analyze the fluoride concentration in different toothpaste samples. The analysis of the different samples coincide with the values reported on the manufacturers label.
