Okay i was watching TV while having whitestrips on and fell asleep. I woke up 1:25min later and it said to "wear strips 30minutes. Now today my gums or teeth feel a lil bit wierd. Kinda like when you drink something really cold. It did say that "some people may experience tooth sensitivity or gum irritation when using whitening products-this is temporary and not harmfull." It doesn't feel bad but its a weak constant pain. Is this anything that i would need to worry about? My mom was like ur teeth are going to fall out because its peroxide.
