Can I wear whitening strips longer than it says?!
Question: I have Crest Whitening strips and have used them for a while. But I was just wondering if it is okay to wear the strips longer than the 30 minutes it says to? I know my teeth will hurt I have forgotten them on my teeth more than once, haha. But, will they continue to whiten with the same consistancy after the first 30 minutes?

After 30 minutes, they are not as effective. I don't think it would hurt if you have left them on longer.
No, after 30 minutes there is not enough gel left to really whiten your teeth much more. If it was okay to do this it would be written on the directions.
dont do it, i tried it, all it does it ruin ur enamel and make ur teeth very sensative
