With normal toothpaste, the fluoride will stay on teeth for around two hours. However the Fluoride in a new toothpaste, BioMin™ F, is suspended in particles that stick to teeth for up to 12 hours.
The toothpaste also slowly releases Calcium and Phosphate. These minerals work together to replace and strengthen the enamel.
Professor Robert Hill, Chair of Dental Physical Sciences, who led the development team at Queen Mary University of London, says that remineralising toothpaste makes teeth more resistant to attack from acidic drinks such as fruit juice. BioMin™ F toothpaste is available online and from specialist dental distributors.
