i read all these reviews and wasnt sure but brought them anyhow, my friend uses them and has bright white teeth like she has been to the dentists and had done profesionally, mine after three days are now the same. have got very sensative though but im sure this will go.

Just finished my very first session of Crest Whitestrips and I must say I'm VERY Impressed! I have family in the States and they always rave about them, but living in the UK, It's been difficult for me to give them a proper try. I bought a packet on ebay but the date had expired so I didn't use them. Beware of that by the way - there are lots on ebay that have expired. As far as ease of use, they are a little tricky to keep on your teeth, and they do make your mouth build up with saliva so it's difficult to talk with themon - in fact it's impossible! Fortunately they've started popping up online in the UK and there are 5 different models around. I've only tried the professional effects, but you can choose for yourself which suits you. In the USA you can buy them at most Grocery stores - Target, Walmart etc. The official site is http://www.3dwhite.com.

I have only used this product for 2 days now (twice a day) and i can already see a real difference. my teeth have been a horrible yellow for years. I never believed that i could do anything about them as all the other products i have tried never made a slight difference. I can already see the whiteness coming through and i cant wait to see the end results. It has already made a boost of my confidence. I bought the crest supreme of ebay for £26 for 42 strips and it is worth every penny and more. supreme is the best strips as they have twice the whiteness.

now for the down side

your mouth fills with water when wearing these and it can become slightly annoying

I have had very sharp pains in my teeth while wearing these but it goes away after a couple of seconds but everybody is different. I think the pain is deff worth it and if you try this product i guarantee you will say the same
THEY REALLY REALLY DO WORK!!!

Fantastic the strips beat any teeth whitening systems . if you suffer any sensitivity just miss a day and your fine. the result is well worth the slight discomfort

This is a really good product, I got it today.

I had heard about these strips and wasn't sure...
They are so simple and in two weeks my teeth are (after twenty years) actually looking really white. Amazing that they're so difficult to buy in the UK. Im 50 and I wish someone had told me about these things years ago.

I first used Crest whitening strips 2 years ago and yes they are great! However, you will feel some sensitivity after using them for a few days, maybe up to week but this passes! Be sure to use a good mouth wash to keep your gums and teeth strong and healthy and a good toothpaste with the strips on a regular basis. I recommend the "Arm and hammer" brand of toothpaste. My teeth are really white and I get complimented a lot on them! I am ordering more now after 2 years to brighten my teeth a bit, but the whitening hasnt faded very much! Would recommend to anyone.

My husband and i are just finishing the 2 week course of these strips and our teeth are so much whiter! We have recommended it to two people already! A great product!!

Crest white strips are such a great product. Having bought several whitening products in the past that did absolutely nothing, I was dubious about these. So I bought 7 strips off of E-bay for £9.00 to test them out. They're brilliant. I had extremely yellowed teeth due to smoking and drinking coffee, but they are now mostly white with a slight hint of yellow There is a little sensitivity, but I find that it goes not long after removing the strip. However, I've just ordered more as I've seen incredible results from just 1/4 of a full course and would recommend these to anyone.

I loved using these! I had a brace for just over a year and felt very self concious about my teeth, because although they were what the dentist called healthy they were yellow and discoloured. I do not smoke, or drink and I would not recommend for smokers as they will not last very long. But i used the Crest SUPREME for a week and really did notice the difference in about three days. My teeth are now pearly white and I buy every six months and use for a week to maintain. Please note a friend of mine had her teeth professionally whitened in the dentist and my teeth are whiter than hers now. I STRONGLY RECOMMEND THESE THEY ARE A BARGAIN! LOVE THEM!

Firstly, I should say that I very rarely write reviews for anything...however, I felt compelled to do so on this occasion!

I'm the first to admit that I haven't looked after my teeth. Being a heavy smoker and compulsive tea drinker meant that my teeth were very yellow and stained. So much so that I always made sure that I had my mouth closed in photos!

I bought the '3D advanced' strips and have been using them daily for two weeks. I certainly noticed a marked difference in the shade of my teeth after three days and they have gradually become whiter day by day.

I should add that I haven't had any problems with the application of the strips, nor the burning sensation that some people have reported. I have however noticed that my teeth have become SLIGHTLY more sensitive than usual.

I by no means have glistening Hollywood teeth but, hey, I never expected to do so. I made sure that I took a photo of my teeth prior to using the strips and I can really see the difference after two weeks when I make the comparison.

I really do feel more confident to show my teeth off now (even if they still aren't quite as perfect as I'd like them to be!)

I Have been using crest whitestrips supreme for two days and already noticed the difference!! they are fiddly and cause a bit of sensitivity but if they do cause too much sensitivity just use them once a day and avoid too cold or too hot drinks for a couple of hours i wouldnt reccomend doing them at night as they make teeth uncomfortable in the morning. Cost wise you can get them for £18.95 for a 7 day course on ebay. They definetly work but just be careful you dont get it on your fingers or gums. I would have liked to know that before i bought them as i learnt the hard way haha

I brought a sample of this product to try and i definately noticed my teeth were whiter. I have just brought more strips and it definately makes your teeth whiter, i have had no pain whatsoever the only thing i have had is when i was removing the strips some of the gel got on my fingers and it started to burn me! i quickly washed it off and it was fine but luckily it hasnt done that to my gums, i brought these so my teeth will look whiter b4 my wedding and ill definately use them again nearer the time.

I have just ordered my first batch of whitening strips and can't wait to try them, all I hope is that I have good results as the system I paid £250 for from the dentist wasn't much good at all, I've got my fingers crossed.
