Teeth Whitening + Chipped Tooth Q&A

I used Crest whitening strips the other day for the first time. One of my bottom teeth, right below one of my two front teeth, has a small chip on the top corner from accidentally biting down a fork when I was younger. It hurt somewhat the first day but 2 days later I am experiencing so much pain that it is making me sick to my stomach. Do I need to go to a doctor or just wait until the affect wears off? What can I do to lessen the pain?

My teeth are chipped and yellow. I gave up smoking 7 weeks ago and promised myself I would get them fixed if I gave up smoking. Can I get these teeth whitened (will it work)? Or do I need to get the chips fixed first?

Hi I have a little chip on the corner of my from tooth, I have whitening strips but I'm wondering will it whiten my filling? Or how badly will it affect it? My teeth are a little off white so would it be noticable?

Had my front teeth chipped as an kid..Now It has discoloration on the false portion and I can clearly see where the my real tooth and false tooth join each other..I hate it
