The new crest professional white strips are the best thing ever made!!! I noticed a change in the color of my teeth within 3 days.My family & friends all noticed & asked what I was using.They are so easy to use & they stay in place & do not slide off.I can not believe how well they whitened my teeth.

If you're looking for a cost effective way to whiten your teeth, this product may be for you. I've tried this product twice and each time my gums became more sensitive. Despite every effort to keep the gel from touching my gums, the product slides because it's not a true fit.

I used this product for a week. Honestly I'm not sure I am getting any results. I took before and after pictures and it's hard to tell for me. If anything my teeth are probably one shade lighter. I stop using them after a week because I was getting teeth sensitive and I didn't like it. It started after two days of use. I stopped folder the strips over at the bottom of my teeth because I was getting the sensitive on the bottom/tip of my teeth. It seem to have helped but then a few days later I started to get it everywhere and so I stopped using it all together. Maybe with continued use I would have gotten better results. The strips are very easy to use and they actually stays put. They have super adhesive, I was actually able to drink with them on and they did not budged. It takes a bit of pulling to get them off my teeth. I was looking forward to getting whiter teeth. These are just not for me but may work fine for someone else. Maybe my teeth weren't yellow enough to be whitened, I don't know…

I was very disappointed with this product. I religiously did it for the allotted amount of time and read the directions thoroughly, however, saw no results. I was about to go on vacation and wanted a nice white smile. Please don't waste your money. There are much better products out there and those will show results and won't cause teeth sensitivity.

These work really well! They are easy to apply, you leave them on 30 minutes. If you use them a few days in a row it can make your teeth a little sensitive but if you use a sensitivity toothpaste its not so bad. Great alternative to in office whitening.

I was amazed at how quickly this product got my pearly's polished and white. I noticed immediate results! I used the trio of the strips, the toothpaste, and the mouthwash and have to say it is the perfect way to get a glowing smile - fast. Is it wrong that I actually looked forward to using the products each day? I must say, it's quite satisfying to watch your teeth become a mouth-tastic masterpiece. Whether you are getting prepped spiffy for a date, have a reason to celebrate or need a reason to start smiling more - these strips will give you the confidence and the results you need. I would not use any other product!

I used to use these regularly, I definitely notice my teeth get whiter but it makes my teeth super sensitive! I now only use them on special occasions and have found that cutting the strip in half helps! Since the strip is smaller it doesn't touch my gums and doesn't leave my teeth feeling sensitive! Plus you get more uses!

You can definitely see results from this product if you use the strips multiple times, you won't see any significant changes after just 1 use. It does make your teeth sensitive to cold and hot for the next day or so after a treatment so be prepared for that. It also makes white “spots” on your teeth instead of your whole tooth becoming whiter, so make sure you prepare to do multiple treatments to balance these spots out. Overall, it does do a good job of whitening though if used correctly.

Crest 3D whitening strips are easy to use and works really well. After about a weeks worth, you could start to see the difference. Although it did not give me sensitivity, some of my friends did get some sensitivity, so be aware of the pros and cons of it. Overall very good produce and would recommend it!

Do you recall the old cartoons sound affect that accompanied a great big smile? Whether the smile was used to cover up a sneaky behavior or to show great pride....CHING!!! accompanied a great big and brilliantly white smile. Well, that is what 3D White Whitestrips Professional Effects has caused to replay in mind every time I confidently flash an ear to ear smile. Many people have commented on my white teeth. My son got his braces off and was a bit surprised at some of the staining.....but only until he used the strips. Then....BAM.......BANG.........BOOM.......CHING!!!!!!!! He restored his smile too!
