A dental hygiene system handle including a proximal grip section, a central control section, and a distal brush section, the central control section including four elastomeric lands for receiving the thumb and forefinger of a user on opposite sides of the central control section.

Dental hygiene system handle

A toothbrush which is particularly well adapted for properly cleaning tooth surfaces and interproximal areas having a plurality of tufts of bristles mounted in the head of the toothbrush with the tufts cut in a series of at least two rounded peaks extending laterally across the head and in which the tufts of bristles may be arranged in at least two longitudinally disposed outer rows defining an inner area lying therebetween and at least one longitudinally disposed inner row is positioned in the inner area, with the tips of the inner row of tufts of bristles being feathered.

Toothbrush with bristle configuration adapted for cleaning tooth surfaces and interproximal areas

The present invention relates to dental hygiene devices carrying dental hygiene elements and to a method for assembling them. The dental hygiene devices have two intersecting cavities, with a dental hygiene element positioned in one cavity and a plug positioned in the other cavity. The plug engages a portion of the stem, thereby locking the dental hygiene element in place in the device.

Dental hygiene device with easily mounted and identified dental hygiene element

Dental floss case

A dental hygiene system in which a single elongated handle having a recess in its distal end receives a plurality of carrying members holding different dental hygiene elements. The carrying members have resilient portions retained in the handle recess by way of either a latching portion in a slot in the handle or by way of a frictional fit in the handle recess. A lever is positioned in the slot in the handle for releasing the carrying members with the latching portion.
