Wire Part
¿I can apply the wax to the wire portion of my keys?

When I had my cable brackets before, do not cut inside the cheek, but when I got my cable in it long horizontal cuts on the inside of the cheek, I can put dental wax on this? If so how?

The wax not only looks good on cable. It sticks better to the media because there is more surface. If you need to cover much of its lead throughout the mouth, you may want to consider getting a cover for comfort or lip protector instead of wax.
