I remember how the pamphlets that came with my curling irons always had a warning in them along the lines of, "Do not use while asleep!" You're going to be the reason why this warning appears on the whitening strips' literature in the future! Ouch.

As the hydrogen peroxide oxidizes the colorants in the dentin layer of the tooth (in other words, as the whitening gel does its job), it incites a pulpal (tooth nerve) response. This is the sharp pain you may feel. Most whitening strips that you can take home and use are not too concentrated... probably 15%. The OTC stuff might be even less. The 35% concentration should only be used for 30 minutes but the 15% concentration instructions actually say you can sleep with them in. And even if you are awake, you can keep them in for up to 3 hours. The OP should brush their teeth to remove the remaining gel. The sensitivity *should* disappear within an hour or so.

I never thought about how they could mean "Do not use and then fall asleep while using." I always thought that they literally meant do not fall asleep and then start using. Now I feel kinda blonde.. no offence to all the blondes out there :)

I once read one that said 'For external use only. Do not insert into an bodily orifices.' my first reaction was ok who the hell did this before that caused this stupid warning. I think it might have said while turned on. Though that could be my twisted mind thinking it was there.

I always get sleepy when I lay down, so I tend to fall asleep in situations like that too. but if I do, I always notice before and if I really don't wanna sleep I just get up and do something to not sleep in.

#6 that's how it is for me too. I was thinking the same thing. I work hard to fall asleep. Apparently we're the only ones.

I was wondering if anyone was going to mention that...Can't believe it wasn't the first comment. Something like "see, TV does teach people things, just look what happened in the same situation on Friends"

My teeth ache in sympathy pain. FYL and YDI. FYL because leaving white strips on can cause irreversible erosion of the enamel, and getting "fake" enamel replaced is more pain and money for ya. YDI because that was just stupid.

Impossibleeeee! The chemicals in the strips are only active for the thirty minutes so that dumbasses like yourself won't disinigrate their teeth. We all appreciate your attempt though ; )

Where the hell did you hear that from? Not true. I've left on whitening strips on for an hour and they were in pain for the next 24 hours. Also, now, whenever I use them, my teeth get extremely sensitive. Also, you've never heard that whitening strips give you sensitivity?

Well my dentist for one, the box itself. They can cause sensitivity, but it doesnt' leave white streaks, the chemicals inside the strips are only active for the 30 minutes.
