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

Definitely on the affordable end when it comes to whitening strips! They do the job after a few weeks (2-3) of usage. So you may need to buy more if you buying the smaller size. They are good for those who have sensitive teeth and/or are afraid of harsh strips damaging their enamel. These are far less harsh than other strips and to me that is priceless! Being that these are more affordable and don’t break the bank as badly, I certainly recommend!

I love these whitening strips! Overall i give a 5 because I LOVE the Guru Nanda brand.Pros and cons:1) the strips are not super long in width. They do not go far back at all show mostly all of my Back teeth, and my top back teeth are not covered with the strips. I might end up using four strips in one sitting because I do want all of my teeth to be the same shade. (The black lines in the pictures show where the strips stop at for me)2) I do love the stickiness of the strips. You don't get that nasty slimy feeling like normal whitening strips. They are definitely easy to keep on for the time recommended without bothering your mouth at all.3) the strips are very thick and you can tell it is doing the work while you have them on!

Okay guys, these are actually good. I've used three strips so far (two express and one professional) and my teeth are at least three shades lighter. I didn't have any issues with packaging quality/damage like some of these other reviewers experienced. They're affordable and work, and I will be purchasing again when I need a little brightening up.

So a lot of people said that these didn’t make their teeth sensitive but they did for me and I do not have sensitivity issues normally so I thought that was odd. They definitely did make my teeth look whiter within the first 3 days which is great but they only provide you with 7 days work of product. Also I found these at Marshall’s for cheaper lol but I would use these again.

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!

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.

This is after only one use. The moment they arrived in the mail today, I used 1 of the 2 “express” strips that came along with the other 12 “professional” strips. I followed the directions exactly. I’m truly shocked at the effectiveness after just this one use. I’m writing this review about 12 hours later now, and the effects appear to be lasting so far. The sensitivity is minimal, if any at all. I’m glad I decided to try these first, at a fraction of the cost of the big name brands. I intended on spending the high price for those fancy brands, but I came across these first, and I hesitantly decided to try them and save myself some $. I’m so glad I did.

these teeth whitening strips are THAT GIRL!!!! after just the two express strips my teeth are multiple shades whiter. i cant wait to see what they look like in a few days after i finish the 7 day treatment!! i have super sensitive teeth and these haven’t caused any sort of sensitivity or issues for me. BUY THEM!!!
