This double-sided Brush Tip was created in order to soften the transition into toothbrushing for young children who are accustomed to using the Z-Vibe. The soft, pliable bristles allow for gentle gum massage and teeth cleaning. Perfect for providing tactile and proprioceptive input to the tongue, cheeks, palate, and lips. The added vibration of the Z-Vibe can have a soothing and calming effect for children with sensory issues. Each tip is constructed of medical grade silicone.
