Abstract
A toothbrush includes a head having multiple cleaning elements. One set of the cleaning elements is longer than the other and relatively rigid. That set alternates with a shorter, springier set of cleaning elements. The flexibility of the shorter springier cleaning elements facilitates penetration of the longer cleaning elements into the interproximal area of the user's teeth.
