Which is the best teeth whitening kit for a smoker?

I keep my teeth very clean but they are stained because of my smoking I suppose. Can anybody recommend a good teeth whitening kit that will work for smokers

The best teeth whitening kit that I have used is the Idol White whitening pens. They are real easy to use and you can get a free trial. I use it all the time and it works. You can read the review about it here http://www.home-teeth-whitening-kits.co.…
