    • Great
Zero pain, awesome results for a beginner! First time trying the I Smile Whitening Kit and it worked like a charm. Absolutely zero gum irritation or sensitivity, so I didn't even need remineralization gel afterward. Simple to use and comfortable to wear. 10/10 for first-timers!

    • Smile Confidently!
Review Image by Hailey Rardin
Let me tell you- photos don't do this product justice! This is the best teeth whitening product I've ever used, and I've tried a lot of different whitening products over the years. After reading countless reviews and looking through everyone else's before-and-after photos, I decided to give it a try myself! My teeth had been very yellow for years, and it made me incredibly self-conscious. I brush and floss twice a day, use mouthwash, and still couldn't get the results I really wanted. Now? I actually get compliments on my smile! I no longer hide my teeth in photos or give the closed-mouth smile. I smile big and confidently now. My own before-and-after photos were taken in the exact same spot a little over a week apart, using only natural light from a window with no other lights on. For the best results (in my opinion), I used the product for 30 minutes a day on completely dry teeth. One tip that worked really well for me was placing paper towels under my tongue to absorb saliva. Keeping both your teeth and the whitening gel as dry as possible seemed to make a big difference! I also didn’t have any sensitivity, which normally I do with whitening toothpastes/strips. If you’re considering purchasing this product- do it! You won’t be disappointed! I give this a solid 10/10! ... show more

    • Good Results with Consistent Use
Review Image by Reinier
I've been using this whitening kit and overall I'm happy with it. It's easy to use, the instructions are straightforward, and the mouth tray fits comfortably. After several treatments, I noticed my teeth looked a bit whiter without causing excessive sensitivity. I'm giving it 4 stars because the results aren't immediate and it takes consistency, plus I wish it included a little more whitening gel. Overall, it's a good value for the price and I'd recommend it to anyone looking for an at-home teeth whitening kit. ... show more

    • WORKS! Sensitive teeth friendly
Review Image by Paulina
It definitely whitens and it’s great if you have sensitive teeth. I usually can’t whiten my teeth because then I end up not even being able to open my mouth, because even exposing my teeth to air hurts SO BAD. This product didn’t give me any sensitivity, I didn’t even need to use the blue gel. It DOES irritate gums though, but what I started doing is placing the product with a little brush. Absolutely RECOMMEND ... show more

    • Can’t beat the price and how well it works.
Review Image by Sasha
1. Price: Can’t beat it. 2. Easy to use. 3. Really improves your teeth appearance in terms of cleaning out and lifting stains. 4. Value: a great value for the money. Whitens really well! My recommendation is to swipe clean or previously brushed teeth dry with a paper towel bottom teeth 1st, apply a light layer to each front tooth part of your visible smile- use a qtip. Do the tip after in the same manner. After application, have your light and mouthpiece ready; place it and bite gently not to give you TMJ pain (you can hold with your hand if it helps) Turn the light on and wait ten minutes til it beeps off. Instructions encourage a 30 minute wear time but ten minutes is good enough if your smacks aren’t that bad looking. Side note: It helps to use a good electric toothbrush whitening toothpaste and floss everyday- it only adds to the whiteness of your teeth. If you’re not doing that and just whitening people will notice the in between and crevices of your teeth dingy yellow or whatever (ick). But no judgment, sometimes you can’t get white teeth maybe because medications you take so there’s that. But honestly bestie, it works so well I even like it over the 60-70$ crest products! The reason you should QTip it on is you don’t want to get any on your gums where the sensitive issues come in. So by doing it this way your not over applying and wasting your treatment gel. If you end up getting sensitivity you can use a remineralization gel that they conveniently provide. It comes with clear instructions and anyone can do it. Pair with your favorite whitening mouthwashes and gum for on the go saliva action to keep the teeth whiter. I’ve been whitening at home for a long time and over the years there’s always something “new” but I’ve been quite pleased with this whitening kit by ismile. Do you think they should sponsor me bestie? 🤭☺️ your teeth will have their own glow up party. Let me know what you think I hope this helps! -Sash ... show more

    • It’s strong!
It works but wow! The chemicals are strong! It burned so badly in my mouth I left it in for only 3-4 minutes.. not the prescribed 10 minutes. So if u have sensitive skin use it wisely. Teeth are more whitened but I will not use it again.

    • Why the iSmile Whitening Kit is the #1 Best Seller in Teeth Whitening
Review Image by Amiri
1. “Amazing Results in Just a Few Uses!”
I’ve been using the iSmile Teeth Whitening Kit for a week, and I’m blown away by the results! The LED light and 35% carbamide peroxide gel worked together to whiten my teeth by several shades. The tray is comfortable, and the included remineralization gel really helped with sensitivity. For $25.99, this is an incredible value—highly recommend it! 2. “Super Easy and Effective!”
This whitening kit is a game-changer! The setup was so simple, and the LED light activated the gel perfectly. After just a few sessions, my teeth look noticeably brighter. The professional-grade syringes are a bonus, and the fact that replacement gels might be available is a huge plus. Definitely worth every penny! 3. “Best Purchase for a Brighter Smile!”
I love my iSmile Whitening Kit! The design is sleek, and the 22 whitening strips included are a nice touch. My teeth feel cleaner and look whiter after only a few uses. The customer service even confirmed that replacement trays and gels are available, which makes this a long-term investment. Five stars all the way! 4. “Quick Delivery and Fantastic Results!”
Thanks to Prime Two-Day shipping, I got my iSmile Kit in no time! The LED light is easy to use, and the results are stunning—up to 3 shades whiter in just days! The kit feels professional, and the remineralization gel is a lifesaver for sensitive teeth. Can’t wait to order more gels when needed! ... show more

I really like this teeth whitening kit. I saw a change in my teeth's color after the first use. You do have to use it about once a week in order to keep your desired results. The one thing that I would change is in my pictures... there is only one of the pieces that you have to screw onto the tube in order to properly track where the gel is going. If you do not have that piece, the gel just kid of goes where ever. That means that you have to unscrew and save that piece after every tube. I wish they would just come on each tube. I don't use the mouth pieces from the box since I have clear retainers, since they are formed to my teeth they fit more snug. However, I have used the mouth pieces from the box and they work just fine. I like that the light shuts off on it's own after 10 minutes, as sometimes I forget to set a timer. ... show more
