Ive been using Crest Whitestrips for years (Advanced Seal) and always noticed a huge difference. I received soo many compliments and people were always asking me what my secret was. I recently used the entire box of Professional Effects (Luxe) and honestly so no changes. Not sure if there was any change in the formula but i am a bit disappointed. I still think its a great product however and should definitely be given a shot

Love this toothpaste! I'm super conscious of my teeth and am always trying to keep them healthy and white -- and this definitely keeps them shining! The minty taste isn't my favorite, as it sort of leaves a bad after-taste, so I would recommend following up with a mouthwash if you're looking for the minty fresh breath.

[This review was collected as part of a promotion.] I havent used white strips in years, and theyve clearly improved. I remember them being very flimsy and hard to stick to your teeth. These felt thick and they adhered to my teeth very well. I had immediate results with these, I just wasn't able to use the full treatment due to sensitivity. The first treatment my teeth felt sensitive while I was using it, but I had a few treatments after with no effects. Then I started getting longer lasting sensitivity again. I probably would make sure to use sensitive toothpaste in between treatments. And maybe do the treatments every couple days.

[This review was collected as part of a promotion.] I feel so lucky we got to try these strips. My daughter just got her braces off and used these to whiten around where her braces were. After a few days she has noticed a difference. The packaging is cute and my daughter is displaying them on her vanity:

I recently had a root canal, which resulted in a crown. My dentist asked if I bleach my teeth? I explained I only whiten with Crest WS. He said my teeth were so white, he had to submit a special order to whiten my crown even more in order to match. He was very surprised that I've never had my teeth "professionally" bleached... THANKS CREST WS!

[This review was collected as part of a promotion.] I used these for the required amount of time but didn't notice much difference. My gums feel healthier after consistent use; almost feel thicker, which is kind of cool, but my teeth look basically the same. Maybe they just didn't take properly? Taste is fine, they stick well compared to the old ones I'd tried (which also didn't do much). Better quality overall than other similar products. My teeth just don't bleach I guess.

The package claims that you can see visible whitening after only 3 days. This claim is true. I've never whitened my teeth before but they weren't too yellow to begin with and I noticed the difference after 3 days exactly. However, I also have sensitive teeth and by the third day, the strips had increased their sensitivity. The instructions say that if your teeth are sensitive, start using the strips every other day (instead of every day), so that's what I did. The sensitivity stopped immediately after skipping a day. I used the rest of the package in a similar manner: using the strips every other day, sometimes using them two days in a row. The whitening continued just fine using this method. My teeth are extremely clean looking now, but not that fluorescent look some people get with over-whitening. They just look pretty and clean. A few notes on usage. The strips are easy to apply, especially if you follow the instructions and put the bottom one on first. I definitely recommend, as the package says, to use them BEFORE you brush your teeth. The instructions say it will reduce tooth sensitivity but there's also another benefit: if you use them daily before you brush your teeth, you won't forget to do it AND you can brush off the gooey stuff that the strips leave behind on your teeth. Also, the strips are EXTREMELY sticky. They won't come off accidentally; they stay on securely. They are comfortable to wear. When you pull them off, make sure your fingers are dry so you can get a good grip to pull off the strip.

[This review was collected as part of a promotion.] The Crest whitetening strips are a very easy to use product to create a brighter smile. They come with a very sticky adhesive that will firmly stay on your teeth for the 45 minute duration. After the first use you can already see a benefit. The only thing is that my teeth are quite sensitive, so I cannot use this product everyday.

This worked really well for hubby but I saw no big difference for myself. I suspect it's because my teeth weren't particularly stained just needed brightening. I wanted to be in a different range of white but that wasn't the case. I would recommend though, for people whose teeth are stained.

Before trying this, I tried the Listerine Dissolving Strips, and those were gross and did not work at all. I just started using these Crest ones since yesterday, and they work wonders! You see results right away ! By the time I finish this treatment, I feel I'll have the best smile I've had without the embarrassment! Everyone should definitely use Crest Strips!
