Natural Paste vs Fluoride
Dentists warn that natural toothpastes do not necessarily protect against tooth decay unless they contain fluoride. A British study examining 500 products from 95 brands found that around a third were fluoride-free, while a Cochrane review of 96 studies confirmed that fluoride toothpastes help prevent tooth decay. Experts recommend a fluoride concentration of at least 1,350 parts per million for adults and children over seven, and brushing twice a day for two minutes, then spitting out the toothpaste without rinsing immediately. You can choose a toothpaste that combines natural ingredients with fluoride. There is no conclusive evidence that charcoal toothpastes are superior, and their particles may scratch tooth enamel.
