I was very impressed with how easy they were to use, just simply open the pack, press on ( they stick right on & form around your teeth), & wait. Results will happen before you even notice it! Even better is, you can still continue to drink your coffee and tea without worrying about your teeth getting stained again. The whitestrips protect your teeth from build up and residue as well.
For continued results the best way is to continue use for the Crest 3D toothpaste and mouthwash, and you will be amazed!
