The labels “natural,” “herbal” and “organic” do not mean that a toothpaste prevents tooth decay. Fluoride helps protect enamel and repair damage caused by acids, and a 2021 UK study found that about a third of nearly 500 toothpastes from 95 brands did not contain it. Research suggests that some plant extracts may help reduce plaque and gum inflammation, but the evidence does not show that they are a substitute for fluoride. Charcoal toothpastes may be more abrasive and can wear away the tooth surface. The UK National Health Service recommends that adults use toothpaste containing at least 1,350 parts per million of fluoride, brush twice a day, and spit out excess toothpaste without rinsing with water.
