You have to take them off after the set time in the directions depending on which one you get!
I would suggest the crest white strips. Although the rembrandt whitens in 2 hrs its not THAT big of a difference especially for how painful it is. I have used both and though the crest strips take longer they whiten better
The original Crest Whitestrips have been discontinued. Crest White Strips Supreme take 21 days for a full effect and last for 18 months. In comparison, the regular Whitestrips took 14 days to take full effect, but only lasted for 12 months.
I always take care of my teeth, and like to keep them white all the time. I highly suggest you buy whitening strips which can be found in any drugstore. I recommend crest white strips. I have used crest white strips a few times and after you're done, they leave your teeth extremely white. It also saves money, I mean going to a dentist to whiten teeth can cost hundreds even thousands. However whitening strips range from $20-$40, saves the money. And after that you can purchase whitening toothpaste to maintain the whiteness.
There are two strips: one for top, one for bottom. You are just supposed to put them on (with the jelly side ON your teeth) and keep them on for...I think about fifteen minutes. Then, you just take them off and rinse your teeth with cold water.
3 hours
Wear a white shirt and white pants, paint your face and hands with a mixture of white and gray face paint, spray temporary white hair dye into your hair, then take that sheet you were thinking about wearing and rip it into ragged strips. Take the strips and either safety pin them onto your clothes or sew them on.
