TartarEnd was initially developed as a mouthwash and does not need abrasives to remove tartar and plaque. TartarEnd was formulated into a paste to make it easy to apply to a toothbrush.  TartarEnd uses saliva to liquefy and spread its ingredients so they can penetrate, dissolve, and soften tartar while the vibrations of an advanced sonic toothbrush remove tartar and plaque.
