The first thing to do is find the cause. It's most likely caused by smoking or drinking coffee. If you don't brush your teeth every day, that could be the cause too. I would recommend that you brush twice a day and limit the amount of coffee you drink and stop smoking. To whiten your teeth, you can use whitening toothpaste as well as whitening treatments to whiten your teeth.
