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

These Crest 3D whitening strips are seriously effective! I noticed a difference after just a few uses—my teeth looked brighter and cleaner without any harsh sensitivity. They stick well and stay in place, which makes it easy to go about my day while using them. The results feel professional without the expensive price tag. Definitely a simple and convenient way to freshen up your smile at home!

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's a great product that works. I left the strips on for 2 hours. And my teeth were so white, I decided not to use the light. I drink 3-4 cups of strong coffee everyday, and they are still really white (after one application over two weeks ago). My gums were a little sensitive after 2 hours, but that only lasted a few hours after usage. Just be aware if you leave on more than 60 minutes. Then brush and rinse really good. I use their "brilliance" tooth paste as well.

Definitely worth the money I love these things, the following picture is a one week difference. You can get it cheaper without the light but the light definitely makes a difference and speeds up the process twice as much. My teeth arnt sensitive afterwards and if they are I just skip a day.

These work really well! I feel like the light makes a huge difference. Rating this a 4/5 because I feel like the light makes my teeth more sensitive, as it's a bit harsher. I've had this for about a year, and I've only used it two or three times for special occasions because of that. I originally ordered this because I don't have sensitive teeth, but with this specific kit, I do.

The gold standard in at-home teeth whitening. Easy to use, and they work!

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.

Works amazing. Four uses (i spread apart the last two treatments and only used for 30 minutes instead of 60 because of minor sensitivity) and results are already incredible. I had an injury to my front two teeth so they probbaly won't ever get perfectly white without dentist intervention.

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.
