Fluoride is important as it makes the enamel more resistant to plaque. At TFI Connect we recommend that children start using a low fluoride based toothpaste between two and six years of age. Once they switch to fluoride toothpaste, we recommend using a very small amount (approximately half the size of a pea). This is the case as most children will swallow a small amount. It is also important to drink tap water as this has the optimum amount of fluoride (approximately 0.7ppm) to help prevent tooth decay in children.
