ARK’s Brush Tip Combo Pack includes two different textures: one soft version and another slightly harder version. Both tips were designed to assist with dental care and oral massage for individuals who are accustomed to using the Z-Vibe® or DnZ-Vibe®. The softer Brush Tip has pliable bristles, which allow for gentle gum massage and teeth cleaning. The harder Brush Tip can 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. The added vibration can have a soothing and calming effect for individuals with sensory issues. Each tip is constructed of medical grade materials that are FDA compliant and contain no lead, phthalates, PVC, BPA, or latex.
