Chewy Tubes are an innovative oral motor device designed to provide a resilient, non-edible, chewable surface for practicing biting and chewing skills. They provide great oral proprioceptive input especially for those who demonstrate teeth grinding and mouthing of non-food objects. The Blue Chewy Tube has a larger diameter and thicker wall than the Red and Yellow Chewy Tubes. Intended for adolescents and adults, the Blue Chewy Tubes offer the greatest resistance to work against for those with stronger mouthing muscles. Non-toxic, latex free, non-flavored and compliant with FDA standards.
