Remineralising Toothpowder - 60g Alumnium TinBig Blue Cosmetica
100% natural, non-foaming but super effective, old school, salty (not sweet!) toothpowder.
You only need to use a tiny bit each time, so one little tin will last at least 2-3 months.
To use simply wet the head of your toothbrush, dip into the powder, tap off and brush teeth as usual.
