Crest 3d Vivid White Strips

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 used to wear braces, and after I got them removed, they left marks on my teeth. This made me want to try every single teeth whitening products in the market.

After watching tons of YouTube videos with ladies having really white teeth after using this strips and after reading lots of good feedback on the internet. And my friend tried this and worked for her.

I have decided to try it myself, I was so excited to try these. I mean, by watching the videos they seemed like magic! So yes, I followed my friends instructions, she was even there to see if I'm doing it right. After getting them on my teeth, they feel weird for the first 5 mins. It was quite hard to put it and you have to make sure that you don't talk or move your mouth. After 10 minutes, the scariest thing happened. I felt as if my teeth were dissolving, they were feeling weird. It kinda stings and hurt at the same time. I never felt that way before. I left it on for another 3 minutes, thinking it was just the strips working its wonders. But it got worse and I got worried so I took them out. My teeth felt really weak and sensitive and they left ugly white marks on my teeth(which didn't last a week). It was a scary experience and I was so gutted since I thought it would worked for me, and it was expensive as well.

These were really successful in Whitening my teeth, even though I didn't do the entire course. I was worried because my teeth became a little sensitive. I'm scared of damaging the enamel. It's now been a couple of years since the first time I did them and I have another course to try. I haven't seen any long term damaging effects so I'll go ahead and do the next ones. I'm just a scaredy when it comes to teeth. These really do whiten, they're easy to use, I wouldn't drink water while wearing them for fear of drinking the bleach - that wouldn't taste too great...but theoretically, yes, you could drink with them in...though I tended to just hang around with my mouth half open and drooling a little....they're intrusive, lets be honest. Which is fine, but I certainly could not whistle with them in. If you are brave enough to go ahead with the bleaching, then yes, these do the trick.

I have always had a poor relationship with my teeth- I have an overbite and it really bugged me when I was younger. This meant I didn't look after my teeth well growing up and they were discoloured. I have pretty sensitive teeth so was hesitant to try the Crest strips. I read lots of good reviews but there was quite a bit about sensitivity.

When I used the first strip, it was very easy to use and stuck very well to my teeth. The next day my teeth were quite painful.I started using sensodyne that day- rubbed some directly on the sore teeth and began brushing my teeth with it. This has completely removed the sensitivity for me and I have been using the strips everyday since.

This is probably tmi but I tend to have lots of saliva - I have had trouble with previous whitening brands sliding around in my mouth. Generally I end up taking them out early due to this. The Crest strips really stick to your teeth- especially using the tip below. I actually have had to make an effort to remove them- this for me is reason enough to keep using the strips.

My teeth are at least 5 shades lighter than they were before I started. Overall I am very pleased and would 100% recommend them.

I purchased these off Ebay after seeing Shaaanxo use them with such success. They do a fantastic job at whitening up your smile. I find them easy enough to use and they get results.

They're easy enough to use. Open the packet, peel them off the clear plastic then attach to your teeth for 30 minutes. I wouldn't go out with them on as they do feel slightly odd. Also when you remove them they're slightly gummy!

I have noticed slight sensitivity after using them but I found that they were well worth the money and I will be repurchasing.

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
