    • Really great teeth whitening kit!
I am honestly surprised by how well this whitening kit works, especially for such a great price! The light makes the process quick and easy, and I started noticing a difference in just a few uses. My teeth look brighter and cleaner without feeling sensitive, which has always been a problem for me with other whitening products. The tray/aparatus is comfortable to wear, and the whole process only takes around 12 mins, so it’s easy to fit into my routine. I love that I can get professional-looking results at home without spending a fortune at the dentist. Definitely recommend if you’re looking for a convenient way to brighten your smile! ... show more

    • My Smile Has Never Looked Better 😁✨

This teeth whitening kit really works. I noticed a difference after just a few uses, and after a full week, my teeth looked noticeably brighter and cleaner. It is easy to use, comfortable to wear, and perfect for anyone who wants professional-level results at home without spending a fortune. 😁 The gel has a pleasant taste, and it did not make my teeth or gums sensitive, which is something I was worried about. The LED light is lightweight and fits comfortably while I relax or scroll on my phone. I usually use it at night as part of my self-care routine, and it feels good knowing I am doing something that makes me look and feel more confident. 💃🏿 My smile looks fresh, polished, and camera-ready now. I love how it helps my lipstick and gloss pop even more. This has definitely become one of my favorite at-home beauty tools, and I will keep it in my regular routine. If you want a brighter smile and that confident glow, this is worth it. ✨🤍 ... show more

    • Works pretty well
I am a daily coffee drinker and was glad to try this instead of other whitening strips. They made my teeth a couple shades whiter and not hard to use at all. Just twice a day for just 20 mins per session.

    • Be careful .The gel will burn.
It does seem to be whitening my teeth a very slight amount after using four time but be careful because it will burn your gums and under your lips. I accidentally let my lips touch the top of my teeth when the solution was in pace and it burnt the flesh under my lips horribly. My mouth was swollen, burned and turned white. The burn healed after a about four days and the white burned skin peeled off. Just be very careful to only get the whitening gel on your teeth which is not that easy. ... show more

    • Can’t beat the price and how well it works.
Review Image by Sasha 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

    • Want white or whiter teeth ~ you need this
To begin, about 10 years ago my dentist made molds of my upper and lower teeth to start my journey into teeth whitening. Needless to say, had to purchase my whitening product through his office. 3 vials at a time every 6 weeks $75.00. Did that for 6 years, then just started using whitening toothpaste. So recently, while cleaning out a few things from my vanity, I noticed my molds and decided to check out Amazon for a product that would be comparable to what I was using. When I found iSmile and read a few reviews, figured to give it a try. Actually couldn’t believe price, like $55.00 less than what I was paying. I have used it 4 days now at 10 minutes, my teeth are actually way whiter than what I remember from 4 years ago. This is extremely easy to use. Based on some reviews, I’ve read that several are stating that globs of product come out. Others suggested to use q tips. I get that, but in the kit there are 4 clear applicators with caps (just like those that I used way back). All you have to do is remove the blue cap from the vial, and insert the clear applicator. Keep in mind, this applicator has a very small opening. At this point you can do 1 of 2 things. #1 - simply squeeze a small dot of product on each tooth, preferably the center and begin whitening. #2 - if placing product directly in the tray, do not place it on the bottom. Place it above the bottom (as on the rim) keep it low, close to the bottom and begin whitening. Both methods were instructed to me by my dentist. With the clear and correct applicators , globs of product is not released. So, all said, if you truly want white or whiter teeth you absolutely without a doubt MUST get iSmile. I believe you will never find anything better, and at such a ridiculous low price. ... show more
