Yes they do work.
They definitely work for me. After the first couple of times, I didn't notice a difference, but after a week, my teeth were definitely lighter. They might not make your teeth bright white, because that might not be possible for your teeth.
The active ingredient in the strips can make your teeth hurt a little or a lot. Maybe it would be better to use them once a day, or even every other day.
They work well, but you need to make sure you follow the directions perfectly. Now the results vary from person to person but expect whiter teeth when you are done. You mentioned that your teeth hurt. This is a common side effect of any whitestrips. This tends to go away after a few days if not sooner.
