3D Whitestrips Sensitive & Gentle + LED Light – Teeth Whitening Kit, 1 Light + 14 Treatments, Each with 1 Upper/1Lower, 28 Strips – Crest 3DWhite Teeth Whitening Strips

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.

It works! Buy it!

Perfect for my sensitive teeth...I skipped a day or 2 between treatments to let my teeth return to normal. I'm giving 4 stars for 2 reasons: 1. top and bottom strips are not long enough...they don't cover enough teeth. 2. doesn't seem to get between the teeth very well...not enough product. I try to press it in but it just doesn't get in there well.

Been using this for about a week now - I highly recommend taking a foto of your teeth on day 1 for comparison. By day 4 - I noticed a difference and took a foto for comparison and definitely my teeth were lighter. Full disclosure- I drink 3-4 cups of coffee a day, often smoke a cigar once a day, and drink some decaf chill out tea at night. So my teeth have a lot of room for color improvement. Today will be day 7 and I will take another foto for reference. Sorry, I'm not posting the pics, I really don't like the look of my teeth since they've gotten a bit crooked over the years. I also recommend that you dry your teeth a little before applying the strips and use your nail to press the strips into the little spaces your teeth might have. I don't notice any taste that is "bad". Basically just dentist type stuff that is sticky. 30 minutes goes by really fast, and then 5 minutes with the light is also over before you know it. Then taking the strips off can require a little bit of focus. They stick really well if you apply them into dry teeth. As for gum pain, I noticed a little irritation on day 3 then just adjusted the strip placement as i realized i had part of the strips covering my gum and that solved the problem. Since then, no issues. So far I really like this product and I'm looking forward to seeing my teeth at the end of next week.

I’ve tried a few whitening kits before, and this one’s definitely my favorite so far. The strips are super easy to use, and the LED light actually makes a difference—I noticed my teeth looked brighter after just a few uses. I have pretty sensitive teeth, but these didn’t cause any pain or irritation, which is a huge win. The taste isn’t bad, and the strips stay in place well. It’s a bit of a splurge compared to regular whitestrips, but totally worth it if you want something that works and is gentle. My smile looks noticeably whiter now, and I feel more confident using it!

It's been many years since I used an at-home whitening treatment like this because I experienced pain the last time that I used one & had to stop. So, I thought I'd give these Sensitive & Gentle strips a try. Before I rate them, I should mention that I have never smoked, been a coffee or tea drinker, or habitually eaten anything notorious for staining teeth. So, they weren't horrible to start with, just not like those bright white teeth one sees in ads. That said, the positive is that I experienced no pain whatsoever & they did whiten my elderly teeth somewhat which is the best that I can say about them. But, since I'm not one to give up easily, I will repeat this treatment when it is safe to do so rather than wait 20 years.

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!
