The instructions were to place the strips on your teeth for 2 hours at a time, but it said to use the strips twice in one day which would mean a total of 4 hours with strips on. Confused? I was. The box which was roughly $50 came with four sets of strips which would allow you to bleach your teeth twice, and the instructions say to bleach your teeth a maximum of twice per year. I can tell a difference, not sure if the pictures do it justice. I will be using them again. The only problem I had was the day after my teeth were sore which is to be expected.
Remember the episode where Ross (from f.r.i.e.n.d.s) has neon teeth? Love.
