I started using those Crest Whitestrip peroxide teeth whiteners. Three days in and I was extremely pleased with the results. But last night I stupidly put my strips on at 11:30 intending to read for a half hour and take them off (the usage time prescribed on the package) but I dozed off and didn’t reawake until 2:00 in the morning. Now my teeth are super super sensitive and I can barely work because the pain is starting to give me a headache. I’m told the effects are temporary and I should just discontinue the strips for a few days, but right now…OW!! Plus I’m so embarrassed about whitening my teeth I’m afraid to tell anyone why I’m so quite this morning.
I used them too, and they did make my teeth hurt once or twice (though I didn’t leave them in like you did!) But I was happy with the results. I plan to use them again when the time comes.
