Profile: Dyna-Dental Systems offers oral hygiene aids, toothbrushes and preventive dentistry products. We offer a revolutionary new tool for oral hygiene. Our hyG, ion toothbrush with ionic action uses basic physics of body energy, to help get teeth cleaner, protect plaque-prone areas, and prevent gum disease. Our hyG-2's ionic action works better than ordinary brushing for plaque removal. Brushing with the ionic toothbrush actually helps teeth repel plaque, even in hard-to-reach cracks and crevices between teeth. It temporarily reverses polarity of the tooth surface from negative to positive, drawing plaque towards the negatively charged hyG toothbrush head. Our hyG system includes the electronic handle, 5 interchangeable brush heads, a power source tester, and a snap on sanitary travel cap. Super Soft bristles are also available in junior size heads for children, or users with sensitive gums.
