New! PikstersTM bristles reach into and clean the indents on the surfaces between your teeth- especially at the gum line of molars and premolars. Floss is not as effective in this situation, although it is very effective in other areas and should be used in conjunction. PikstersTM remove plaque & food particles in areas normal toothbrushes don't reach as effectively. Plaque is a significant factor in decay and gum disease. Decaying food particles also cause bad breath. Note to Dentists: Color of handles follows same size sequence as endodontic files.
