Hi I have had me teeth whitened about 6 months ago but they are begining to turn yellow again, I guess with the food I eat and stuff there is nothing io can do i am a heavy smoker and I drink about 5-6 cups of coffee a day.

I have seen there are many different types of teeth whitening toothpastes on the market such as colgate simply white one called super smile whitening tooth paste and one by jaina (sp). Anyway my point is that if i was to have teeth whitening again to get my teeth to the whiteness they were last time will a teeth whitening toothpaste keep them white afterwards? If so which whitening toothpaste brand would you recommend ?

Also if you have any other tips in keeping my teeth white after treatment other than stop smoking and drink less coffee! that would be appreciated.
