I have sensitive teeth and gums. In the past I have not been able to use whitening strips on my bottom teeth. I tried these strips and they worked great. No pain from sensitivity. Love them!

Update!!!!! Currently I'm using aligner after my braces and I want my teeth to be look healthy and white. First I got them original crest 3d level 20 but my teeth got super sensitive on 3rd day. So I switched to this one and I ddnt get any sensitivity or any problem at all. my teeth looked so good and healthy for just 8 days. Worth it & love it so far. Ps: More whiter inperson. Ddnt took a picture before but I uploaded my teeth before braces. Ty Update year 2026 my 2nd box treatment. Im telling you guys this is the one that realy works. I tried the other 3d crest which cheaper (without light) but wont work. This item realy works + Use 3d whitening deep stain remover toothpaste indicates (whitens teeth in 1 day.) And make sure to get sensodyne Thanks me later

So far so good. I tried for the first time and it seems to work. I'll tell you how it goes. No sensitivity yet which is great for me.

I’ve been using it for about 7 days, and so far, it works well. I haven’t experienced any discomfort while using it. After my first use, my teeth were very white, but the next day, they seemed a little bit yellow compared to how they looked initially. I hope the results last longer!
