Question by matt: What happens when wearing teeth whitening strips for too long?
I bought the Crest Advanced Vivid whitening strips and as I was beginning to wait for the 30 min wait, I accidentally fell asleep and ended up wearing the strips for like 7 hours. Now my lower tooth is sensitive and hurts a little. Will the pain go away and do i need to get this checked up or something?

it seems you might damage the enamel. Don’t leave them on longer than required.
