"My teeth already feel sensitive sometimes with cold drinks, so I'm worried gels might make it worse."
Totally get where you're coming from—I was super nervous about sensitivity too. When I first tried whitening gels, my teeth did feel a bit more sensitive for a couple days, especially with cold stuff. Honestly, it wasn't unbearable, but it was noticeable enough to make me cautious about using them too often. Have you thought about trying one of those sensitivity toothpastes beforehand to see if that helps at all?
I've had similar issues with sensitivity, especially after whitening treatments. One thing that helped me was applying the gel for shorter periods at first—like half the recommended time—and gradually building up. Also, using a fluoride rinse afterward seemed to calm things down a bit. Sensitivity toothpaste is a good call too, but it didn't do much for me personally. Have you tried adjusting how long you leave the gel on? Might make a difference.
I've been dealing with sensitivity too, especially after whitening strips. Tried the shorter application thing you mentioned, and it did help a bit, but honestly, not as much as I'd hoped. Fluoride rinse was decent, but what really made a difference for me was spacing out the treatments more—like every other day instead of daily. Have you experimented with frequency at all? Also, weirdly enough, drinking room-temp water instead of cold afterward seemed to ease the discomfort a little. Not sure if that's just psychological or actually helps, but hey, I'll take it if it works...
"what really made a difference for me was spacing out the treatments more—like every other day instead of daily."
Interesting you mention that—I actually tried spacing mine out every two days after my dentist suggested easing into it. Definitely felt less sensitivity overall, though results took longer... trade-offs, I guess.
I spaced mine out too—my teeth are super sensitive, and daily treatments were a nightmare. Every other day was way more manageable, but yeah... patience required. Still, better slow than sorry with tooth pain, haha.
