Brushing should start as soon as the first baby tooth erupts. Brushing should be carried out twice a day, and this should be supervised by an adult until at least 7 years old.
Children under 3 years should use no more than a smear of toothpaste and must not eat or lick toothpaste from the tube, as children will have a tendency to swallow toothpaste, which would then mean that they had an excessive flouride intake – this can cause “flourosis” of the adult teeth, causing the teeth to be greyish or flecked.
