It does not cause tooth sensitivity, once applied it is really comfortable and holds well; by continuing to use it consistently, my teeth have become whiter in different shades!

After using them for three weeks, my teeth are much whiter, the yellowing has been significantly removed, the whitening effect is fantastic!

I have tried these whitening strips and, after just one application, you can already see that the teeth are whiter; the yellow stains on the teeth have been removed very well.

The teeth pads for yellow teeth work great! I haven't even used half a pack yet, but the discoloration has already significantly reduced and my teeth look much cleaner.

When i tell you that there is an instant difference in color i mean it is basically magic! my teeth look bright white after use and only takes 2 minutes of brushing! this product is genius! like i said the difference in color is instant you will be super happy! i'm not sure if it does anything long term but it definitely keeps your teeth bright white for the day!
