There are a few things you can do. Whitening kits such as Crest White Strips, whitening toothpaste, whitening mouthwash. Also stop or limit the amount of acidic drinks such as soda, coffee, and juice. Adding a sprinkle of baking soda to your toothpaste will also help remove some stain....but be careful to not over do it. You do not want to remove too much of your enamel.
