The ARK Tetra-Bite™ Chewy Fidget is a versatile oral motor tool and silent sensory fidget in one. With four uniquely textured arms, it’s designed to provide calming oral sensory input while also offering a discreet outlet for fidgeting – perfect for children and adults with autism, ADHD, anxiety, or sensory processing challenges.

Each of the four extensions offers a different surface – smooth, ridged, or bumpy – giving users multiple sensory feedback options. Its symmetrical, geometric shape is easy to hold, rotate, and chew, offering proprioceptive input to help with self-regulation, focus, and calming in both home and classroom settings.

Made from medical-grade materials and available in three colour-coded firmness levels (sold separately), the Tetra-Bite™ supports oral motor development, jaw strength, and provides a safe alternative to chewing on clothing, pencils, or hands.

• 4 chewable arms with varied textures for multisensory input
• Doubles as a silent fidget tool – ideal for classroom or on-the-go use
• Helps support attention, anxiety management, and oral motor development

Caution: This product is not a toy.
Although the Ark chew tools are sturdy and durable, no chew tool is indestructible. Some individuals particularly those with strong oral sensory needs or who chew aggressively may be able to damage them in a short period of time. The lifespan of each tool depends on a variety of factors, including individual chewing intensity and whether the user is receiving support from an occupational therapist.
Please supervise use at all times and replace the item if it shows signs of wear and tear. We are unable to offer refunds for chews that have been used. Finding the right chew is often a process of trial and error—please contact us for help and advice.
