The basic concept is to approach toothbrushing as a joyful game. The shark shaped toothbrush will easily attract children who get trouble tooth brushing. Furtermore you could also use the toothbrush as a water pistol just incase the children get fed up. with the shark gun you are no longer just toothbrushing you are "toothplaying"! How to use? open the cover. Put in water. Grab the toothbrush. Press the spin to exhale water. The 'Sharkgun' is not only an ordinary toothbrush. but it could also be used while gargling and also as your child's favorite toy.
