Perfect for whitening!
This Puur Smile whitening kit is now a must have in my home ! I always wanted to have whiter teeth but going to a dentist is too expensive. I decided to buy this kit to try it out and I am very happy with my results ! The kit is very easy to use and you have a manual. I love that the Puur Smile led device has 2 modes , for sensitive and extra sensitive teeth . It does not irritate my teeth and gums . You don't have to hold it on for long , 10-15 minutes per session is enough. After using it I noticed significant improvement of my teeth color , it is whiter and I am looking forward to making it even better with future sessions.

Very good
I really liked this teeth whitening kit. It comes very complete with an LED light, whitening gel pens, and a shade guide to track your progress. The instructions are easy to follow, and the design is practical and comfortable to use. After several uses, I noticed my teeth looked a bit brighter and cleaner. I also like that the device is rechargeable, which makes it convenient and easy to use anywhere. Overall, it’s a great option for at-home teeth whitening.

Must have!
I am honestly blown away by the Puur Smile Teeth Whitening Kit — it’s become a must-have in my self-care routine! From the moment I started using it, I noticed a visible difference in the brightness of my teeth. Even stubborn stains from coffee and wine have faded noticeably after just a few sessions. The kit is super easy to use, and the instructions are clear and straightforward — no fuss, no mess. I love that it doesn’t cause sensitivity like other whitening products I’ve tried in the past. The LED light feels gentle, and the gel goes on smoothly without irritation. My smile looks brighter, cleaner, and more confident — and I’ve already gotten compliments from friends and coworkers! The results feel professional quality but at a fraction of the cost. If you’re looking for a reliable, effective, and gentle whitening system, this kit is a total winner. Highly recommend! 😁✨

Haven't seen an extreme difference
This looks to work about as good as any other teeth whitening product out there. It has the whole mouth piece with the light, i can't say is actually doing anything special. The real magic seems to be whatever is in the tubes, but the stuff only works about as well as any other whitening strip i've ever used. You'll get a few shades whiter, but nothing absolutely crazy. I think for the trouble of applying and then wearing the mouth piece to throw the light on to get the whole thing going, i'd rather just use burst white strips or something similar.
