GuruNanda Teeth Whitening Strips, 7 Treatments

There was noticeable whitening after the first and second applications. After that the whitening was much more gradual. Overall, the whitening achieved was okay, but certainly not great. Teeth that started out more discolored than others did improve somewhat, but still remain more discolored. The biggest problem with these strips is the size, but most especially for the bottom strip. These strips need to be stretched out in order to cover enough teeth. This is not much of a problem with the upper strip. However, it is very big problem with the much smaller lower strip. It is hard to grip and then to pull on the ends of the lower strip with sufficient force to get it to stretch out enough to cover most of the visible teeth. If you apply too much force, in an attempt to get a sufficient stretch, a piece of the strip is likely to break off. Also, compared to the larger upper strip, it is more difficult to maneuver the smaller stretched lower strip into place and to get it to adhere well. The bottom strip definitely needs to considerably longer. It would also help if both strips were wider. This is because the strips obviously thin out when stretched and, for some teeth, it is difficult to get adequate coverage in the direction of the width of the strip.
