Just started teeth whitening with trays that you use overnight which I got from my dentist. I thought about doing this for a long time as I am really self conscious about the colour of my teeth so decided to give it a try.
The first night was fine but after the second night my teeth are hurting this morning, not just sensitive but like zingy pains. I actually took the retainer out after 5 hours as it was starting to feel uncomfortable and rubbed some sensodyne toothpaste on the teeth. I was told about sensitivity but is this what they mean?
I hardly used any bleach the first night but last night I think I may have used too much? And I only did the top teeth last night but this morning the bottom front teeth are a bit zingy too. Don't quite understand that!
Im not in a lot of pain but I'm not going to do it again till they settle down but is this normal?
