BugBrush is intended to be used throughout the day, after meals and snacks, or when the child is in their high chair or pushchair, or even in the bath. The child quite simply chews it. This action removes food debris and plaque, increases salivary flow and reduces the chance of tooth decay. The child can use this as much or as often as they like. There is no harm done by the child using it all day. It’s self-limiting.
