Most invisible braces are made of zirconia, a material often used in aerospace, defense and atomic energy fields, and also in pacemakers. Invisible braces are made of high-molecular nanomaterials.

        Regular cleaning of braces involves removing the invisible braces, carefully scrubbing every part inside and outside the braces with a hard-bristled toothbrush, and then rinsing them with clean water. If you use a soft-bristled toothbrush, you can add a little toothpaste to increase friction and make cleaning easier.
