The active mineral binds to the enamel of your teeth, to protect them against decay and to strengthen them.There's protection. And there's triple protection. Only Aquafresh has three stripes for triple action: fights plaque, fights decay and freshens breath. This unique formula provides highly effective fluoride protection by making the enamel less soluble and promoting remineralisation, with a taste that leaves your mouth feeling really fresh and healthy. Choose from the ultra fresh-flavoured Fresh'n'Minty with its blue and red gel stripes; or Mild'n'Minty which has a slightly milder mint taste and comes in green and red gel stripes.
