There are more things you can do to whiten your teeth besides switch toothpaste, visit your dentist, and use whitening strips and trays. Even if you’re already taking these actions, there are several other steps you can take to brighten your smile without spending a lot of money.

Swap Your Toothbrush More Often

Trade out your old toothbrush for a new one every three months or whenever your bristles start to look faded and worn. Doing so ensures that your toothbrush is always providing the proper friction for scrubbing your teeth cleaner and whiter.

Avoid Eating Dark Pigment Foods

No matter how much you might like blueberries, marinara sauce, soy sauce and other dark foods, they aren’t doing your teeth any favors. Such foods can leave stains on your teeth thanks to their dark pigmentation. While not all dark foods are necessarily bad, it’s a good idea to limit how much of these types of foods you eat and make sure you enjoy them with plenty of water to help reduce the chances of staining.

Use Apple Cider Vinegar

While not as powerful as other whitening methods, rinsing with apple cider vinegar is a natural way to help brighten your smile (though perhaps not a very enjoyable one). To make the most of this tip, you’ll want to rinse your mouth out for a full minute with a mixture of one part apple cider and two parts water.

Avoid Drinking Energy Drinks

Besides dark foods, tea, coffee and red wine, energy drinks have also been known to cause staining on your teeth due to high acid content. Acid is also found in citrus fruits, so you’ll want to be careful of those as well. If you simply can’t go without your energy drink or soda, it’s better that you drink it through a straw to keep the liquid from coming into direct contact with your teeth.

Making a few small changes can do wonders not only for the color of your teeth, but for your overall oral health. Pay attention to the small signs that your teeth and mouth might be giving you about the state of your teeth to get a whiter smile and a healthier mouth.
