I have never had more sensitive teeth in my life !! I will say this, the stuff works. It really does, it made my smile incredibly white and people noticed... However, I didn't want to smile. Because, god forbid a gust of wind land upon my teeth!! I was unpleasantly surprised to have at least a week of overly sensitive teeth --from the chemicals I'm assuming. They do say pain is beauty.. But is paying an arm and a leg also beauty? I'm left wondering if the plain-jane store name brand might have given me the same result for a fraction of the cost. If I'm going to have to suffer with sensitivity I'd at least like to save a dollar or two

after so many years of wine,coffee and many more stuff i dont have a nice white teeths so i give a try to this whitestrips and wow i see a little difference right away after the first use so it good

I don't really like to whiten my teeth all the time because of past experiences, but a friend recomended it to me so I tried it and I saw drastic results! It worked! The product does what it says it does and if you're looking for a quick whitening treatment without going to the dentist, I recomend that you give this product a try!

bon produit qui fonctionne en 2h00, j ai vu une difference de teinte immediatement apres la prmiere application.

These Crest 3D white 2 hour express strips are great. Easy to apply, taste pretty good & can be used for up to 2 hours for effectiveness. Just apply on teeth & wait. Bit pricey but many in the pack & used well can last a long time if used 2 hours each strip. Easy teeth whitening solution.

I have sensitive teeth as it is. I used to use just the regular white strips when I was younger no problem. Tried these and WOW. My teeth were sore for a whole week. I couldn't even open my mouth outside because the air was painful against my teeth. I couldn't imagine doing this in the winter and going outside.. ouch. I wish these didn't hurt so much because they are so convenient. I'm sticking to my whitening trays that i wear over night.

I tried these strips over the summer and loved how clean & white my teeth looked. It was great that the time was only for 2 hours and the strips stayed in place the entire time with only a slightly horrible taste (other strips are much more grotesque). They did do what they said they should and I had beautiful results the only down side I had was the discomfort after I removed the strips! My teeth were very sensitive for days. I love how efficient they are but would only use them now for a very special occasion since the pain afterwards required me to take Tylenol to less the pain. (by special occasion - I mean like ultra special as in I am meeting my celebrity boyfriends RDJ)

Crest 3D White 2-Hour Express Whitestrips

I tried whitening strips 5 years ago only to end up with a Salivary Infection so I was quite apprehensive to try them again.  I started using the Crest Pro-Health line about 3 months ago with great results and decided to give it a go because it is manufactured by Crest and I only have to have it on for 2 hours instead of 30 minutes for 2 weeks.

I found applying the strips incredibly easy, getting them off the plastic took me longer as i don't have long nails.  Once applied I did notice a small burning sensation at the tip of my tongue that lasted for about 15 minutes after that it was full speed ahead.

I kept the strips on for the full 2 hours and just passed the time writing up my other Elle reviews.  I found it easy to talk and not the least bit uncomfortable.  The strips stayed in place the entire 2 hours and were very easy to remove.

There was a white semi foamy residue on my teeth that didn't taste wonderful but it was not horrible either.  I suggest you rinse immediately after you remove the stirps and try not to swallow until after you after rinsed.

My teeth are a good 30% whiter and the difference is quite noticeable.  Being a tea drinker I will do this one more time next week to see if the will whiten any more.

I received these strips for free from the company in order to sample and give feedback.

I've used Crest Whitestrips before but never the 2 hour express. My teeth going into this were looking pretty good so unfortunately I didn't see a major difference in colour but I'm getting really great feedback from friends on how my teeth look and even my dentist asked if I'd had them whitened!

With the shorter duration strips I didn't have any teeth sensitivity but with these I did a wee bit. Nothing major but enough to mention.

I've heard it promoted that you can wear these and no one will notice but I don't find this to be true. They do get a bit 'gummy' as time goes on and while not hugely noticeable, not invisible either.

Fantastic! The 2 hr crest strips worked gret noticed it right away lots of compliments
