Crest 3D Whitestrips with Light Teeth Whitening Strip Kit, 10 Treatments

These white strips with light were awesome! They did excellent, I could tell they whiten my teeth at least 3 shades I'll use them 2x a year :) [This review was collected as part of a promotion.]

So I don't normally want to whiten my teeth but if but my bad habits of coffee blueberries and red wine was not good for them for them. I was really surprised at how great my teeth feel and look. Totally worth the money. Only negative is the time it takes, but working from home that's a little easier to do

My grandson just got his braces off and wanted to whiten his teeth. He loves this light and he and his momma whiten as a new routine now. Great job crest. [This review was collected as part of a promotion.]

It definitely works. I did 4 days straight and took a break because of slight sensitivity. I gave 4 stars only because the wear time is an hour plus five minutes with the light. Product is definitely worth the money considering going to a dentist would cost $500 and up. Good job crest.

I was hesitant to order these again as I tried them several years ago and couldn't get the strips to stick to my teeth. But, there were many glowing reviews so I decided to try again. After the first use I could see a visible difference in the whiteness of my teeth. Pretty impressive. I had no sensitivity after using the first time. In those respects I'm very pleased with the product. However, it's still a major pain to get these strips to stay in place for an hour. Towards the 30 minute mark I have to make a conscious effort to keep my lips and tongue very still or the strips will slide off. Yes...I'm certain I'm applying the sticky side to my teeth. The strips are a little to wide for me as well. Even after placing the edge of the strip at my gumline the strips hand over the bottom. I've tried to wrap them over my teeth by that only lasts for a few minutes. After that I have this annoying lower third of the strip just dangling away in my mouth. As far as the light goes? Who knows if it really does anything? I guess you could try the strips without the light to find out. At any rate, I am pleased with the change in the color of my teeth after only the first application. I'm finishing up the second application as I type this so I'm curious to see if there's further improvement. And...maybe. It appears the teeth may be slightly whiter. But, it's such a slight change, if any, it may just be my imagination. I'll finish out the 10 days of treatments and hope for the best.

Firstly the little gadget is not chargeable, which means it can only be used while battery last. and talking about effect, it makes no difference with the normal strips without light.

bought this for my wife. she's been obsessive of having her teeth whitened. after the first day she saw results. the 2nd day was better. however after the 3rd day, her gums started become sensitive and gave her pains when eating or drinking something cold. it could be her gums are more sensitive than other people. but this was her outcome. had to stop using this product.

3 out of 10 strips did not stick to teeth. At the end the light only lite for one minute, and is suppose to last 5 min each treatment. Contacted Company and no warranty can be used if this item is not directly bought from Crest.

I don't understand why, but these white strips were useless. I have no opinion on the blue light. I have used many types of white strips and have always seen a difference in my teeth afterwards, but, not with these white strips. I would not waste my money on these.

Based off of the majority of the reviews and product description, I was eager to try these. I paired it with optic white to boost results and unfortunately did not see much of a difference. I drink coffee but I dont smoke, drink tea / wine. This one wasnt it and did not deliver.
