These work! I was on medications in my very early years which caused discoloration on my teeth. My DDS said mine wouldn't ever be radiant white if done professionally. So, i tried white strips. They really brightened my smile. The only downside, imo, is waiting 30 min.

It works great for me and it takes 30 mi ties to 45 minutes which is not bad. You can do it twice per week so it won't take much your time. It helps whitening your teeth

I have always been embarrassed by my stained teeth from medication during childhood. I was always envious of those with pretty white teeth. I was recently at the dentist and told the hygienist of my embarrassment. She asked if I had tried whitestrips and mentioned she had patients that had and had good results. So I gave it a try and I am so pleased I did, NOTICEBLY whiter, the key is to use them consistently (daily for 30 minutes) through the entire kit. I HIGHLY recommend. This kit has 20 days worth and then the additional strips that stay on an hour to maintain!

Really like the results after first use, thinking to get more, it's very comfortable, great value for the product, didn't feel any sensitivity

I absolutely love this product! I've been using it for over 6 months now and it's amazing. I will warn those that have sensitive guns and teeth that this product may make them more sensitive the next day. Usually it's temporary. My teeth have never been whiter and it's so easy to use!

When I tried Crest Whitening it did wonders for my teeth. And I didn't believe that it would because I've used other products that said that they would do the same thing and they didn't. So I was quite skeptical. But, this one is one of the best I've ever used in my life. It was very sensitive to my teeth and the packaging was alluring. And it definitely did whiten my teeth so much so that I recommended it to everyone I knew that needed a whitener in their life. Crest is one of the best toothpaste I know and their whitening strips are also one of the best.

These are my favorite and the only whitening strips that have truly worked for me! The picture attached I have no filter or editing on! People always ask how my teeth are so white and I always tell them these! If you're questionable, GET THEM! You won't regret it!!

I've tried many whitening products but this is the one that really showed a big difference! I used only a few and people already started noticing . I would get compliments daily of how white my teeth looked and the best part is that I didn't have to whiten them for a whole year! They last so long and give me confidence. My teeth did hurt a bit but I feel like that's with any whitening product if you have sensitive teeth . I will 100% recommend to anyone!

Been using these for about a year and they work amazingly. You can see your teeth whitening from the first use! Super easy to use. The only negative thing is sometimes it bleaches my gums for a short period of time but goes away within an hour. Love using this and will be a customer for life!

Crest Whitening Strips are a popular choice for those looking to achieve a brighter smile. Having used the product myself, I would rate it 3 out of 5 stars based on my experience. While it does have some positive aspects, there are also a few areas where it falls short. To begin with, let's focus on the positive side of Crest Whitening Strips. The packaging is sleek and easy to open, which is a plus. The strips themselves are thin and comfortable to wear, making it convenient for daily use. Additionally, the instructions provided are clear and easy to follow, making the application process hassle-free. However, when it comes to the effectiveness of the whitening strips, I must say that it barely shows signs of teeth whitening, especially considering the price point. With regular use over a period of several weeks, I expected more noticeable results. Unfortunately, the strips only managed to lighten my teeth by a shade or two, leaving me somewhat disappointed. Furthermore, it is important to note that everyone's teeth may react differently to whitening products. This means that while Crest Whitening Strips may not have worked effectively for me, they might produce better results for others. It is always crucial to manage expectations and understand that individual experiences may vary. In terms of convenience, Crest Whitening Strips do have their advantages. You can easily apply them at home without the need for any additional equipment or appointments with a dentist. This makes them a convenient option for individuals with busy schedules or those who prefer home-based whitening treatments. On the downside, I did experience some sensitivity while using Crest Whitening Strips. This is a common side effect of most teeth whitening products, but it is worth mentioning nevertheless. It is recommended to use a toothpaste specially designed for sensitivity during the treatment period to minimize discomfort. In conclusion, Crest Whitening Strips are an average choice for teeth whitening. While they do have some positive aspects such as convenience and ease of use, the lack of significant whitening results and potential sensitivity issues are drawbacks. However, it is important to remember that individual experiences may differ, and what may not work for one person could work well for another. It is always advisable to consult with a dentist before using any whitening product to ensure it is suitable for your specific dental needs.
