What are the best at home kits for teeth whitening?

i really don't want to spend a lot of money on a product that will leave my teeth overly sensitive or won't work at all.
--------------------
I agree with a lot of what everyone has said: Brush regularly, stay away from items that can stain such as coffee, tea, and colas, and many of the commercial whitening products really do work. However, I have an additional tip for you. Take advantage of the free trial offers you can find all over the Internet. And I mean, take advantage of SEVERAL of them. Go ahead, order a few of them at once. However, make sure that you read all the terms and conditions, and be sure to CANCEL in time so that you are not charged outrageous prices for your subsequent shipments. So, for example, sign up for the Premium White 14 day trial (http://freetrialreviews.info/teeth-whitening/premium-white-teeth-whitening-free-trial-offer/) and for the 14-day trial of Alta White (http://bestfreetrialoffers.com/teeth-whitening/alta-white-teeth-whitening-free-trial-offer/). You will pay a total of $9.89 for s&h for these two offers. Then, as soon as your trial products arrive, follow the directions enclosed to cancel so that you are not charged anything additional. Theoretically, you could do this over and over again, but after a couple of times, your teeth should be white enough, and you can stop until they start to look a bit dull again. I hope that this helps you out!
