The amount of fluoride in toothpaste is measured in parts per million (ppm). Toothpastes containing 1,350 to 1,500ppm fluoride are the most effective. A dentist may advise people to use higher strength toothpaste if they are at particular risk of tooth decay. In general:

  • Children aged under three years should brush twice daily, with a smear of toothpaste containing at least 1,000ppm fluoride
  • Children aged between three and six years should brush at least twice daily with a pea-sized amount of toothpaste containing more than 1,000ppm fluoride
  • Adults should brush at least twice daily with a toothpaste containing 1,350 to 1,500ppm fluoride.

Age-appropriate products containing the recommended amounts of fluoride are available for children.
