Crest 3D Whitestrips Professional Effects + LED Light – Teeth Whitening Kit, 1 Light + 20 Treatments, Each with 1 Upper/1Lower, 40 Strips – Crest 3DWhite Teeth Whitening Strips

I've purchased these Crest 3D Whitestrips three times now because I'm so impressed with the fantastic results. Unfortunately, I didn't think to take a before picture, so an after photo alone probably wouldn't show any dramatic difference. But I can definitely see in the mirror!I'm 62, and between age and drinking lots of coffee, my teeth had become noticeably darker and stained. These Whitestrips made a big difference and got my teeth really white. I've had my teeth professionally whitened before, and honestly, the results are very comparable.Once my bottom teeth get as white as I want them, I take the extra strips and use them on my top teeth. It gives me several extra days of whitening on my top teeth. It's a little trick that lets me get more use out of the product.I make sure the strips are positioned carefully and avoid getting them on my gums. I have not experienced gum sensitivity and the strips stick well, unlike some other brands I have tried.If you have noticeable staining and have been considering professional whitening, I think these are absolutely worth trying first. They're economical and easy to use at home. The results have been excellent for me and I'd highly recommend trying them.

I'm on day 7 out of 20 and wow I already notice my smile noticeably whiter, it's definitely working as described. I can't wait to see the end result I'm very excited. So yeah you might experience slight sensitivity it really depends on you just make sure to do everything correctly, don't brush before using, don't brush right after using, keep the strips off your gums, don't use for more than 60 minutes, and at 5 minutes remaining use the LED light. Out of the 7 days so far I've only experienced slight temporary sensitivity twice in 1 or 2 areas but it's not uncomfortable, doesn't hurt, and disappeared by the next day. I've been brushing 1 hour after a treatment with nano hydroxyapatite with a brand called Boka and it's supposed to help easy sensitivity more than traditional fluoride toothpaste, I don't know, you might have a different experience, but it's been working great for me.

I’ve only done one treatment and already can see a difference! I did have some slight sensitivity but also did just get dental work done so that could be why. I may do a couple more rounds, but my teeth already look much better.

These actually really work. Noticeably whiter after 3 days.

My dentist actually recommended this in contrast to the products offered in office! So I had to try. I was especially interested in a whitening system that would not sacrifice effectiveness for gum sensitivity. Not only could I see instant improvement, but I had no gum irritation whatsoever, not even next day. So that's the two big things that exceeded expectation. A few drawbacks though - (1) Instructions were unclear as to how long to leave the light on, & I didn't realize until after mixed Internet recommendations & testing it out blindly that it automatically times out after a few minutes; (2) the product unfortunately outlasts the light's battery life, so I had to find a $16 replacement LED on Ebay, & (3) the adhesive will strip your dental work fyi. Not cool, but still overall beneficial as a whitener & hundreds cheaper than true, professional whitening. BTW this before and after were taken within a month of each other.

I mean, this product is simply THE BEST on the market. Just be SMART and don't use the straps every single day because that WILL cause teeth sensitivity. Use every 2 to 3 days. You will LOVE the results! It's worth every penny.Mind you, this may not work for those with severe stains and discoloration. For that you may need professional help. But for those who just want a brighter smile, this is where it's at!

This is well worth the money!

Easy instructions to follow for fantastic white teeth. Little pricey but well worth it.

تركيز الماده كبير ويمرض حساسيه وبلغم بالحلق وطعمها زي الكلور يبقى عالق بالفم لا ادري اذا كنت ساكمل العلاج به همي الان اخلص من الطعم العالق بالحلق من امس

I see the result only in day of 7 I will continue and buy for my family also

Only used once so far and the results are immediately visible. Very surprised but very pleased.

These work wonders, I usually don’t use the entire thing as recommended on the box, since my teeth get super sensitive, but just 2-3 days every few months does the job.

DO NOT BUY.Very harsh chemicals, I used once and it stripped all of the skin off of my gums and gave me huge ulcers. The chemical is hydrogen peroxide and is not suitable for putting in your mouth. Avoid at all costs.
