The Senso® Brush can be used to directly stimulate areas of the mouth both inside and out. The Senso® Brush is an excellent tool for both therapists and parents. Due to its alternating textures, this brush is perfect for children with feeding difficulties. This brush is also a great source of sensory stimulation for children who constantly seek input from grinding or chewing on items such as pencils, shirts, fingers, etc. NOTE: Chew/oral products are not returnable.
