I have found that yellow teeth whiten the best and show the most dramatic difference. Greyish teeth do not whiten as well. If you never whitened your teeth before, you will also see a more dramatic difference.

I agree with dr. Patalowski. My experience too is that yellowish tinted teeth get the best result. Give it a try. You have very little to lose (time and money) and a good upside.

You should be able to get whiter teeth coming from a yellow tint. Grey tinted can be more difficult, so you should be fine. Depending on your goals, simple methods may be enough, such as white strips and products from a store. More dramatic changes are best done under supervision of a dentist.

A yellow color to your teeth is unfortunately the natural color of your teeth and responds the best to professional teeth withering. Unless your dentin is stained from either Fluoride or antibiotics when the teeth were first developing around 2-4 yo, you should have great results.
