Follow the directions inside the box.
You basically peel off the sticker, you get 2 of them, a long thin one, and a short wide one..
The long one is for the top, you put it on your teeth then the left over under and back.
Same thing with the short one
I've used 1 pack, my brother has one and my mum had one..
