Crest whitening strips

They didn't work for me and felt horrible. However I think my teeth are just naturally yellow anyway as I don't remember ever staining them in the first place.
 
I've got some of these and have been using them for 7 days. They've made a massive difference, almost enough for me to stop using them already.

Not noticed much difference after one application, but wasn't expecting to.

Will see after 7 days, if nothing I will prob stop using them.

I'd be weary of using these products. The hydrogen peroxide used in these products has been linked to cancer. Not from contact with the teeth, but the solution coming into contact with the surrounding tissues i.e. gums. So maybe there is an argument for going to a dentist and getting a custom fitted tray.

That's just like saying be weary of meat, the sun and your TFT Monitor :P

I'm sure the risks are tiny enough not to worry about. Isn't peroxide what people use to dye their hair blonde O_o (No that bit was off topic to the quote but lolz @ putting hair bleach on teeth :P)?

Keep us updated, I will be tempted to buy some due to having a deficiency that makes my teeth slightly transparent.

I bought the crest advanced seal ones, 14 day supply for about £25 delivered around christmas time.
Found i only needed to use them for 3 days to get a nice shade of white, i've since used a set now and again just to 'top up' like before going on holiday, but on the whole its easy enough to keep your teeth at the same level of whiteness.
I was impressed with the results :D
 
Well I have used all of mine bar 2-3.

I had to stop using the bottom ones though, as it made my teeth crazy sensitive. Could be pretty painful, but it goes away after a day or two.

Have noticed a massive difference, considering how yellow they were before. They aren't white, but I wasn't wanting them to be, but not yellow anymore :)
 
I found mine go very white when I complete nearly the entire course of them.

I agree that they do make your teeth very sensitive, can also cause your gums to bleed a little if they touch them. One friend of mine stopped cause it really made his bleed.

How bad was the bleeding? The more I read about it, the more I'm leaning towards seeing my dentist about alternative solutions.. :

With me, it was only a little occasionally, much like when you brush your gums and get a little bit.

My friend made out his was much worse, but I've got no idea whether he was just using them wrong.
 
How are people finding this product after some time using it? Any recommendations as to where I can buy it at a decent price other than the link in this thread.
 
My pack of 28 crest 3d Advanced seal arrived on Friday. After only two strips I can really see the difference already. Can't wait for the final result.
