Crest 3d Vivid White Strips

The first time I used these strips I was in so much pain afterwards but it made quite a big difference so I waited 3 or 4 days before I applied them again and the sensitivity wasn't so bad this time round and have notice more of a difference. So if you can handle th pain its worth it I just hope it doesn't damage my teeth.

I am an avid coffee drinker, and my teeth hate me for it. I was starting to feel pretty self conscious about my teeth looking yellow, so I had a hunt around for what I could use that wouldn't be too expensive. I was watching a youtube video about whitening teeth, and these came up. I thought I would give them a go, so I ordered some.

When I first got the product I was super excited to try them, as so many people had great results from them.

I followed the instructions, and they worked great. However, after the first few uses of them my teeth got super sensitive, and really painful. I found that during my sleep I was dribbling a tremendous amount, because my teeth were so sensitive I couldn't close my mouth.

I would recommend these to people who do not struggle with any sensitivity. I would also recommend that you do not use the strips too often, and leave reasonable periods of time between each use. This should help with easing the sensitivity. I however have not used them again, as I am slightly nervous about feeling that much pain in my teeth again.

This was my experience of them (the sensitivity and pain), but I know many people who did not get this. So I would recommend you think about how sensitive your teeth are prior to buying these, and trying them for yourself. :)

Yes they may work but I'm about to do some research on these strips because I wonder if they are actually ok for my teeth or if I need some work done because I have chips or am allergic. I do them when I can get some on special because in New Zealand they aren't cheap. The result is great and lets be honest everyone wants beautiful white teeth but for me I experience pain and sensitivity kind of like shocks through certain teeth maybe this is because they could be chipped or my teeth are to sensitive for the strips, I'm unsure but it sucks because I'm now nervous every time I use these. I've read a few reviews below and watched some YouTube videos and people have suggested using Sensydone for the sensitivity but is that just hiding the pain from what's really going on when I'm using these? I'm unsure But ill keep you all updated. In the meanwhile Yes they do work, Yes my teeth are amazingly white and Yes I do love the results

I bought these off eBay after seeing rave reviews. My teeth were definitely whiter after a few applications but it is a little patchy - bits of teeth were whiter than others. But this soon evens out. I experienced no sensitivity which was great. Would recommend

This product is really easy to use. The product works quite quickly. The colour is definitely not 'celebrity white' however I am happy with the colour and it is noticeably whiter. I did experience some sensitivity but once I stopped using the product, and a couple of days later this went away.

Quite pricey and didn't see stunning effects - definitely some effect but nothing to write home about. Prefer the clearwhite strips!

I was recommended these whitening strips by my sister after seeing them work well for her. I agree that they work well to whiten my teeth also. They are a little annoying because you need to keep them in your mouth for at least 30mins. But if you wear them while watching TV then the time passes fast. I noticed my teeth were whiter after 1x use, and significantly more so after several uses. They are slightly pricey to use regularly but if you use them regularly, then you can begin to space out how often you need them.

I have used these a couple of times now and I found they are super easy to apply, and gave a noticeable change after the first use. Will continue to use!

Who would of thought these would work? Like actually do what it promises?? Haha not me! But I had to try. I'm glad I did. Will repurchase definitely.

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!
