I've been curious about those LED kits too, but honestly, after years of dental visits, I'm skeptical about quick fixes. Has anyone noticed if they cause sensitivity like the strips do? I'd rather not trade brightness for toothaches...
Tried one of those LED kits last month before a friend's wedding—honestly, I was super nervous about sensitivity too (my teeth are drama queens, lol). Surprisingly, it wasn't as bad as the strips, just a tiny bit sensitive the next day...nothing major.
Glad to hear the LED kit wasn't too harsh for you—I always get nervous trying new whitening stuff because my teeth tend to freak out easily. One thing that helps me is brushing gently with a sensitive toothpaste right after whitening, and then rinsing with lukewarm water instead of cold (cold water makes sensitivity worse for me...). Also, I avoid acidic drinks like coffee or soda the next day, just to be safe. Seems to help keep things calm down there.
Interesting points about brushing right after whitening... though I've actually heard the opposite from my dentist. She recommended waiting at least half an hour before brushing, even gently, because teeth can be temporarily softened and more vulnerable right after whitening treatments. Instead, she suggested just rinsing thoroughly with lukewarm water or using a fluoride mouthwash to soothe sensitivity. I tried it her way last time, and honestly, it felt a bit better for me—but everyone's different, of course.
That's interesting, because my dentist gave me similar advice about waiting before brushing, especially after stronger whitening treatments. She explained that the enamel can be temporarily more porous and sensitive, so brushing immediately might cause unnecessary discomfort. I've found rinsing with lukewarm water or using a gentle fluoride rinse really helps ease that sensitivity too.
One thing I've always wondered though—does anyone have tips for minimizing sensitivity overnight after whitening? I've tried using sensitivity toothpaste beforehand, and it seems to help a bit, but I'm curious if there are other tricks people swear by.
