The rubber construction produces a toothbrush with a wide oval head that flexes back and forth to remind us to reduce the pressure of brushing. Available in right or left hand orientation with a large soft handle for sensitive brushing.The very fine Tynex nylon bristles make it much softer than regular brushes - while the mass of bristle tips (6000 - over 3 times more than regular) massages the gums and removes plaque effectively. The extra bristles make it more durable and 60% of our users report it lasting three times longer.The right or left hand orientation automatically places the bristles at the 45 degrees recommended by the ADA.Other products from HerbsPro
