Get both soft and firm Y-Chews. They can also be used to develop biting and chewing skills and to decrease sensitivities to texture. Because ARK's Y-Chews are a non-food item, you can avoid the risk of choking when working on feeding skills. The handle of the Y-Chews makes them easy for the therapist or individual to hold. The top part of the 'Y' makes it easy to reach the upper and lower back molar area. The resilient, medical grade materials are FDA approved and contain no latex, lead, PVC, or phthalates. Made in the USA.
