Crest 3d Vivid White Strips

I purchased these after hearing great things about them from numerous you-tubers and bloggers and they didn't disappoint. I only used once per week as have sensitive teeth anyhow and most of the time they didn't cause pain. Only minimal discomfort (due to exposed nerves, so probably wouldn't occur for those without this problem). Only once were they for some reason excruciating and I had to remove? Not sure why they were so sore just the once. I have only used about 7 sachets (7 uses) and my teeth are noticeably whiter. Definitely recommended, but just be aware that they may not be pain free.

They did whiten my teeth a little bit but made them so tender ans sore not a good product at all don't use it breaks down your enamel and once its gone its not coming back, and it will make you unable to eat for at least 24hrs. the smell isn't very pleasant either as it smells of bleach yuck!

I found these way to hard on my teeth, after using only 2 strips I had to give up. My teeth are not super sensitive normally but these just plain hurt! I'm sorry I can't review on whether they whiten like they say, from what I saw and heard they are really good but for me it turned into a painful experience :(

The strips are easy to apply and I don't fault them in any way except that they hurt my teeth like they've never hurt before!

I used these before my wedding to make sure my teeth were nice an white. After about 5 uses my teeth were whiter but they seemed to be feeling more and more sensitive after each use. I persevered a couple more times for the sake of pearly whites on my big day but I stopped after that. I wouldn't use them again as they did cause discomfort.

After hearing so many beauty gurus raves about this product, I went and tried it myself. Hmmm I have only used 3 stripes and I couldn't continue cause it made my teeth sore and painful! I can't really comment on the whitening effect cause I haven't used enough to give a full review. I don't have sensitive teeth but it still gave me alot of pain.

I purchased these with a high expectation, because of so many beauty gurus were raving about them. Beautiful pearly whites, and that's what I got! I was really scared about my teeth getting sensitive because I do have quite sensitive teeth but surprisingly no pain! After the first three days (I used a strip every day) I had an uncomfortable feeling (wasn't painful) still used them daily and the feeling went away as soon as I stopped. It didn't worsen. And I can honestly say even after the first strip I noticed a slight difference. Once I finished them, wow! My teeth are so white and completely stain free, I am amazed.

The strips are easy to apply, and if you have your mouth open with your teeth exposed (to dry them) for a minute or so, they won't slip at all. You may have a gel type residue after you remove them, but don't brush your teeth. An hour before or a hour after as the toothpaste creates a barrier. Overall, great product, certainly whiten and brightens teeth, totally recommend.

I try to be careful with my oral hygiene, but my teeth can sometimes look a little yellow. I was looking for something that would be easy and simple to use, not cost too much and not cause problems for my teeth by making them too sensitive.

I liked that these were easy to use and saw results quite fast. I found that they worked reasonably well for a short period of time but their effects soon wore off. I noticed my teeth were also feeling a lot more sensitive than normal.

I do worry about them causing harm to my enamel as I would rather have teeth are healthy and slightly dull looking than bright white with the enamel ruined.

Overall i would probably purchase again if I had an event and wanted to whiten my teeth for it, but I will still keep searching for that elusive perfect teeth whitening product.

I will continue to buy these at this stage, purely because I am yet to fine something better. Pros: *Your teeth definitely look whiter and brighter the next day Cons: *Your teeth are sensitive as heck and your gums ache for 1-2 days after *You have to be SUUUUPER careful of not having anything but water after you use it. It says one hour, but I found even then they still get stained more easily, so I just apply them right before bed *You have to leave them on for 30-60 minutes depending on which one you get (I've used both, and I found the 1 hour ones more effective, but also more sensitising) and it feels quite sensitive while it's on n can sting your gums. *they taste revolting *the whiteness only last 1-3 days (my personal experience, maybe it's because I drink too much coffee!!) *the strips adhere well to the front, but i found they peeled off on the back of my teeth n slid around, leaving this gross tasting bleach-slime.

So, there's my crest white experience, it's not a BAAAD review per say, but at the end of the day, you're bleaching your teeth, those are all to be expected. Beauty is Pain!

Well this was hyped around MUO and by shaaanxo so i had to purchase it (ebay), while i do like it,maybe I'm lazy but i thought it was a bit high maintenance. But beauty is high maintenance. It definitely worked thats for sure and instantly made my teeth a little whiter after one use but it made my teeth a bit weak and sensitive. I hate waiting and i love eating so waiting for 30 minutes before i can eat was a struggle haha. The only thing is you have to constantly use this to keep up with the white teeth or else they will go back to their normal colour again. I did read somewhere that whitening teeth really does break down your enamel which makes your teeth weaker. Ive avoided this since then but i will probably still use this the night before a special occasion or something.

I heard massive raves about this product and seen results from a friend of mine who was using them so, I went out and purchased these.

I got a pack of 10 (5 top and 5 bottom) and after using them for two days my teeth started to get quite achy and sore, it was bearable but still rather uncomfortable.

I feel as though you would definitely need to use these for at least 10 days before seeing results as after I used them for 5 days it was only a very slight difference from when I started using them
