Work Excellent, Sensitive Teeth Friendly
This product works great! I wish I would have taken before and after pictures, but I saw a noticeable difference with the first two uses. I have sensitive teeth and these didn’t bother me at all. I’m a habitual coffee and red wine drinker, and these helped remove all those surface stains and got me back to white teeth!!! And the express treatment is really good for when you have an event and want to boost the whiteness in just 1 hour. I’m super happy with the results, and these are a new staple in my home.Ver másVer menos

Amazing.
Noticeable difference in first use. This product is amazing. I only used the professional, so far. I can only imagine the difference with the express. Can’t wait until my 7th day, is complete. Small coffee stains removed. No sensitivity. Alittle sticky, a tooth brush can remove with quick brushing . I use this product with crest white 1 day tooth paste . Fantastic combo.Ver másVer menos

Effective and great for sensitive teeth
My teeth do not whiten easily and get extremely sensitive with most whiteners from the dentist or available at stores. When I read that this was different, I wanted to try it and I am pleased to day this is my solution! I'm cutting back but i do drink tea and coke, and even with excellent oral hygeine my teeth have always tended to stain easily. Kids used to tease me in school about the color of my teeth, and about a year ago my toddler niece admired my "golden teeth." In spite of her endorsement, I began using these regularly and find they make a huge difference. They whiten very effectively and I only have a little sensitivity if I use them daily, which really isn't necessary. I have to say that I do cut the strips in half lengthwise and apply them only to the front of my teeth. This makes the supply last longer and I think may help cut down on sensitivity. The package includes a card with a color scale so you can monitor your progress. I also use the oil pulling kit and toothpaste from this brand.Ver másVer menos

Great Results, Sensory Nightmare
Like a lot of us, I don’t have money for regular teeth cleaning and was looking for a good at home solution. I was recommended this product and was nervous because I have pretty sensitive teeth and in the past whitening strips have caused a lot of pain. These were gentle on my teeth. No harsh sensitivity after, and I saw noticeable improvement from the first use.My only issue is that it’s a sensory nightmare. Nothing physically prevented me from closing my mouth, but between the strips on my teeth and the ungodly amount of foam it produced I just couldn’t do it. I looked like a rabid dog. It also leaves a film on your teeth but brushing afterwards solved that problem. If you have sensitive teeth wait about 30 mins before eating or drinking anything and you should be in the clear :)Ver másVer menos

It works well. Swallowing saliva or water while using may give you an upset stomach.
Usually I do a pros/cons list, but I only have good things to say about this product with a few caveats.Pros:1. It actually works and works pretty fast comparatively to other products. I have tried teeth whitening toothpaste and a few other methods of whitening my teeth over the years with success only coming from Nu Skins' AP 24 Whitening Fluoride Toothpaste. That however required a month or more of constant brushing and a bottle of it is $25.00. That being said, within my first day, I felt like I could see results. By day 5, I knew for a fact things had gotten better for me.2. It's easy to use. Dry off your teeth, slap this on them, it does all the work. Wait a hour and take it off. Easy as pie.3. I noticed a little sensitivity after a week's use, but it wasn't anything bad at all and went away fairly quickly.Caveat: The instructions say you can drink water while using this. I did so and it gave me a somewhat upset stomach. In fact, swallowing my saliva while using this made my stomach upset. Perhaps I have a weak stomach? I don't know. I just stopped swallowing while using this and haven't had any issues since.Last note: I saw a review saying this didn't permanently keep their teeth white. While there are longer lasting solutions out there than this, considering the cost per results, I think this is a decent deal. For my needs, I brightened up my teeth initially using this daily. However, to maintain them now, I just use one a week. Something to consider.Ver másVer menos

Good teeth whitener. Good results. I like the card that is included in the box so you can see how much your teeth have lightened.

No Sensitivity - Works Great!
I purchased these strips after reading reviews from people with sensitive teeth who said they had no problems—and they were right! I have extremely sensitive teeth, and other brands have caused pain for me in the past.The first time I used them, I left the strips on for 30 minutes to test my sensitivity. I had no discomfort at all, and my teeth already looked brighter after the first use.The second time, I tried using them a little differently. I applied the top strip for an hour, removed it, and then applied the bottom strip for another hour. I personally found this more comfortable than wearing both strips at the same time—especially if you have the extra time.The results after the second use looked great—noticeably whiter and brighter. As the instructions mention, the longer you leave them on, the more they adhere to your teeth. Before removing them, I rinsed my mouth with water, which made them come off more easily. I also brushed to remove any remaining residue.Another thing I appreciate is that they don’t leave the gooey mess that some other brand-name strips do.Overall, these strips are excellent and a great option for anyone with sensitive teeth. I’m looking forward to even brighter teeth with continued use. Cheers to whiter teeth!Ver másVer menos
