- Lumismart Whitening Strips - Dentist-Designed, Enamel Safe, up to 42 Treatments with Smart Adjust - Teeth Whitening Strips in Mint for Sensitive Teeth

I wasn't 100% sure at first, but they definitely work. Love these strips, and love that you can customize the size, you may even be able to get two uses out of each packet. I think they take a couple more uses to really start to notice them working than some more mainstream brands, but my teeth don't get sensitive or sore at all, where they do with other brands. I think it's a great and worthwhile trade off. I've been using these for a couple weeks and I think the coffee stains are totally gone. Glad I finally purchased these!

I’ll give quick instructions all the way at the bottom, these must be used with extreme care and follow all instructions for best results and no enamel damage. Never have I been so sure about a 5 star in my life before. These whitening strips outmatch anything else you might find out there. First picture you will see is the before, and then two more pictures which will be the after. My teeth are sparkly white now. Every picture that I take, my teeth SHINE WHITE. I started these right before my vacation and when I came back? The praise my teeth got from coworkers was so nice to hear. I tried so many other options out there, with the worst being this brand that starts with the letter C. These strips win all of the time. ZERO SENSITIVITY, I thought it would be less effective, but nope. I actually fold them and also whiten the back of my teeth and they still don’t get sensitive AT ALL. Proper whitening routine: 1. Floss your teeth before you brush 2. Brush your teeth. 3 use paper towels or a dry cloth to dry your upper teeth and apply upper strips 4. Use paper towels or a dry cloth to dry bottom teeth (more difficult) and apply lower strips. 5. Wait 45 mins to an hour with the strips on, DO NOT EXCEED THE ONE HOUR LIMIT 6. Remove the strips when the time is due 7. Wait 30 mins for your enamel to remineralize a bit and then brush your teeth again, but this time very gently to prevent any enamel damage NEVER SLEEP WITH THE STRIPS ON AND ALWAYS BRUSH YOUR TEETH AFTER TAKING THEM OFF. 8. Once you finish the box, DO NOT BUY MORE, you have to wait 4-6 months for your teeth to strengthen, if you continue then you could damage your enamel and cause permanent damage that can cause you sensitivity. Whitening strips are only meant to be done twice a year with 6 months in between but supposedly you can use these strips every 3 months but idk if I trust that lol

First off - Do NOT get the watermelon flavor. If you hadnt told me they were supposed to be wafermelon flavored I would never know, they taste so weird and slightly bitter. More like the green rind than the actual edible part. They actually dont slide around which is great because the feeling of whitening strips sliding around on my teeth grosses me out. Ive been using these for almost 3 weeks, and I definitely think my teeth are whiter, but it isn't as noticeable as using crest whitening strips. That being said, crest whitening strips make my teeth so sensitive that I cant actually use them anymore, even just one use makes my teeth hurt for days. This is the first time I've been able to successfully whiten my teeth since high school, and since im a coffee drinker I definitely need it! Personally, I'm ok with needing more treatments for the same result if it means I can complete the treatments to actually get a result. I'm going to pick up another box but I think ill be getting either the mint or coconut, not sure im brave enough to try the peach.

These whitening strips are okay. I like how they don’t irritate my teeth but results are very subtle. The strips aren’t long enough so I stretch them to get my back teeth. They don’t taste horrible but they definitely don’t taste great. They don’t get gummy or slide around like other strips do, but I think I’ll try something else for better results.

This product works wonders! My teeth were yellow for over 8 years, and it noticeably whitened them in just 2 weeks. I used it every day, leaving the strips on for about an hour each time, and experienced no sensitivity at all. I also love that it’s adjustable and I can get 42 strips out of it, which is great value. Overall, I highly recommend this if you want to whiten your teeth quickly without sensitivity.

It whitens your teeth without any sensitivity! I absolutely recommend and I also use their toothpaste a well

I’ve used this for two nights and my teeth are already whiter, I’ll update after I’ve finished the box. As long as you choose the right size from the strip, they’re super grippy. I didn’t realize each strip had three different sizes at first and they were falling off my teeth. I almost returned them. When I used the correct size, they were firmly attached. The mint flavor is good, and there isn’t a bunch of leftover goo on my teeth like other brands.

I tried them for about a week only on my top teeth to see the difference between tiny bottom and top. When I tell you NO difference. I mean no difference. None, absolutely none. It was not white at all, and did nothing. I think the only think theh did for me qas make some of my teeth more sensitive.
