Please press the aligners in place with light pressure and then press the aligners in place with your fingertips with balanced force.
Hold one end of the chewie, put the other end into your mouth and bite gently, moving from one side of your mouth to the other, making sure that it touches every tooth.
After using the chewie, clean it with water and put it back in the box to avoid contamination and loss.
