Abstract
A toothbrush includes a head having multiple cleaning elements. One group of the cleaning elements is mounted on a movable portion of the head and another group may be fixedly mounted on the head. The movable portion of the head is attached by a flexible membrane to the fixed portion of the head so that the membrane is capable of flexing to alter its original orientation during use of the toothbrush and then recover to the original orientation randomly during use.
