The wide oval head, thumb grip and large comfortable handle available in right or left orientation makes this a classic toothbrush - now in its 22nd year of production. The very fine Tynex nylon bristles make it much softer than regular brushes - while the mass of bristle tips (6,500 - 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. Ecologically packaged in a useful travel case. The handle is made of renewable resource cellulose - 93% wood based from sustainable yield forests.
