DnZ-Vibe® is a unique vibratory tool with extraordinary versatility. One end of the handle is sealed off from the internal components so that no saliva, water, or moisture can enter from that end while working in the mouth. The Switch Tip at the opposite end of the handle turns the unit on and off and can be easily removed to replace the battery. The Switch Tip can also be replaced with another tip in order to use two tips simultaneously. And with over 30 interchangeable tips available, the possibilities are endless! These tips of varying shapes, sizes, and materials provide gentle vibrations to stimulate the gums, palate, lips, and tongue. Use them to increase oral awareness, to decrease oral sensitivities, and to improve a variety of skills during feeding and oral motor therapy. While the DnZ-Vibe® is mainly used for oral motor stimulation, it can also be used outside the mouth on the cheeks, neck, and arms for additional sensory input.
