ARK's Brush Tips turn any Z-Vibe® into the ultimate sensory toothbrush.  It's available in two different versions: the Soft Brush Tip (blue) has pliable bristles for gentle gum massage. The Hard Brush Tip (yellow) has firm bristles, to be used as a transition to the eventual use of a regular toothbrush.  Both tips are perfect for tactile and proprioceptive input to the tongue, cheeks, palate, and lips during oral stimulation and/or dental care
