GuruNandaTeeth Whitening Strips - 7-Day Treatment with Non-Slip, Dry Strip Technology - Whitening Designed with Care for a Brighter Smile

I think my side-by-side pic speaks for itself! The before was taken last month. In both pics, I had freshly brushed teeth and hadn’t eaten anything before these pics—although on the Day 5 pic, I had eaten pizza before I brushed my teeth since I was meeting a friend. Both pics were taken on the same camera with flash in similarly lit rooms. And yet there’s a noticeable difference!I’m currently on Day 7. It’s hard for me to discern the level of whiteness my teeth are at using the comparison card they give you, but I think I’ve definitely managed to whiten my teeth by two or three levels. When I look in the mirror, I think I can see a change, but the level of whiteness fluctuates based on the lighting I’m in.Regarding any sensitivity and whatnot, I haven’t noticed any! I’ve steered clear of coffee and other sugary beverages as well as candies so this might be helping. I do admit I have had fillings and whatnot, but I don’t believe these are on any teeth that can be seen when I smile and thus are not touched by the strip upon application.I only use these strips at night before bed. I use the Professional Strips for ~1 hour and the Express Strips 30-45 minutes. I brush 30 minutes before, dry my teeth, apply the strips for the appropriate duration, and then I do a quick water rinse to get rid of the excess gel stuff left behind on my teeth after peeling. You’ll see white spots left behind, but they do go away!I don’t think you’ll achieve the pure white look without professional help, but I think you can certainly get a few shades whiter!

I really appreciate how well these stick to your teeth. Very sturdy, and you can drink water while using them still! That makes for a bit more of a comfortable experience my opinion. I’m on my second box of these. Definitely noticed a great shade difference in my smile :) grabbed a whitening gel pen by this brand to try as well.

The Express should be used for 30 to 45 min because it has a higher strength. So, it shouldn't require as much time as the professional. It only makes sense, it's got to be called Express for a reason. Which explains why there are less than the Professional. Maybe that also explains why some people are stating that they had white spots for a few days because the higher strength is being used for too long. I haven't used these yet, but once I do, I'll update the effectiveness of using this method.

I recently completed the 7-day treatment with GuruNanda Teeth Whitening Strips and I’m genuinely impressed with the results. These strips are super easy to use thanks to the non-slip, dry strip technology—they stay in place the whole time without sliding around or causing discomfort.After just a few days, I started noticing a real difference in the brightness of my teeth, and by the end of the week, my smile looked significantly whiter. What I really appreciate is that the formula didn’t cause any sensitivity, which I’ve experienced with other whitening products in the past. It feels like this product was made with care, and it definitely shows in the gentle yet effective results.If you’re looking for a convenient, mess-free way to enhance your smile, I highly recommend giving these a try!

When I purchased these, I was not looking to have white teeth, my only goal was the decrease the years of coffee and soda stains on my teeth. After two uses, I could not only chart the difference but see it as well. Can’t wait to see what the entire 7 days is use does.

There was noticeable whitening after the first and second applications. After that the whitening was much more gradual. Overall, the whitening achieved was okay, but certainly not great. Teeth that started out more discolored than others did improve somewhat, but still remain more discolored. The biggest problem with these strips is the size, but most especially for the bottom strip. These strips need to be stretched out in order to cover enough teeth. This is not much of a problem with the upper strip. However, it is very big problem with the much smaller lower strip. It is hard to grip and then to pull on the ends of the lower strip with sufficient force to get it to stretch out enough to cover most of the visible teeth. If you apply too much force, in an attempt to get a sufficient stretch, a piece of the strip is likely to break off. Also, compared to the larger upper strip, it is more difficult to maneuver the smaller stretched lower strip into place and to get it to adhere well. The bottom strip definitely needs to considerably longer. It would also help if both strips were wider. This is because the strips obviously thin out when stretched and, for some teeth, it is difficult to get adequate coverage in the direction of the width of the strip.

It’s great, it really does work, but I’m in so much pain. My teeth are just super sensitive so I’m not sure any “tooth sensitivity” teeth whiteners will work on me. Given that’s it’s cheaper than crest whitening strips and gives the same results, I can’t really complain.

These are the ONLY whitening strips I have ever seen results with, or at least results this noticeable! These are so cheap, and actually work. I do notice a bit of teeth sensitivity if I use them too frequently, so I like to use them one week, and then break for a week, and use them again. Sooooo recommend!!! Also, they don’t slide off your teeth at all, you have to rip them off. Awesome.
