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

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

These actually really work. Noticeably whiter after 3 days.

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!

It works. After 4 days my teeth are already looking super white. I am shocked

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.

These definitely work like a charm. I will definitely need to buy this again. I would recommend this to anyone.

Works perfectly every time. So easy to use I love this product. Whiten my teeth so nice.

Works beautifully! Highly recommend! The first two applications made my teeth sensitive but by third application, teeth felt normal. Saves time and money from visits to the dentist.

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

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

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

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.

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.
