Teeth stoking is done to remove the bacteria that remain between the teeth. This gives significantly better plaque removal than brushing alone1. One extensive tooth brushing is only necessary once a day, preferably before you go to bed. The toothpick is used in narrow gaps where a brush will not fit.
A wooden toothpick is often triangular in shape with a long and short side and can therefore be used in places where there is a little more space between the teeth. We recommended a wooden or plastic toothpick, wood is more environmentally conscious.
