If you look in the mirror and see that your teeth are stained and discolored, you may decide that you want to whiten your teeth and get rid of those stains. If you do go through the whitening process, you want to make sure that your teeth stay white. There are a few things that you can do that will help your teeth stay white.
Use a Straw
If you love your colas, iced tea, or other dark drinks, use a straw. Using a straw means that your teeth will have less contact with those dark drinks, which may stain your teeth. When you use a straw, the drink also goes back behind your teeth instead of right up against the front of your teeth, which means that any residue from the drink won't end up where it's visible.
Smoking can stain your teeth yellow. If you are a smoker and you have had your teeth whitened, you may want to consider stopping. The less you smoke, the less your teeth are going to get stained. If you can't completely quit, then you should at least work on cutting down.
You don't want to use whitening toothpaste every day, but you should use it a couple of days a week. That can boost the whitening treatment's efficacy and help to erase nascent stains, which will also stretch the length of time the treatment lasts. When you aren't using a whitening toothpaste, you should be using your regular toothpaste and flossing, so that you don't get any plaque, which is a breeding ground for bacteria that can cause more staining on your teeth.
You may want to go see your dentist for a touch up every so often. When you see your dentist for your regular checkup, you should talk to them about whether or not you need your teeth touched up so that you maintain your preferred level of whiteness. How often you are going to need to have a touch up depends on a lot of things. Those things include your lifestyle choices and the health of your teeth.
If you have spent the money on whitening your teeth because you don't like the staining and discoloration on your teeth, then you want to make sure that you are doing everything you can to make sure that your teeth stay nice and white.
