I had Enlighten teeth whitening (prescribed by the dentist) which made my teeth ache so I stopped using it. It’s been a month and my teeth still ache. Dentist reckons it’s impossible for the whitening to still be causing pain after this amount of time, any discomfort wears off after a couple of days and there’s never been a case of this product causing long term pain. They’re saying I must be causing the ongoing pain myself by grinding my teeth. Except I’m not. I’m starting to feel scared that I have permanent damage and the pain will never stop. Any advice?
