Are you noticing that your teeth are starting to become visibly stained? Does no amount of brushing seem to help it? The reason for this discoloration could be due to the foods and drinks you have every day! Many items have something called tannins inside of them, which turns your pearly whites not so bright anymore. Continue reading to learn more about why this happens.

So, What Are Tannins?

In short, tannins are organic compounds that are found in nature. Some items that are high in them are coffee beans, cranberries, cacao, and grapes. This chemical is the reason they have a bitter flavor that coats your mouth when consumed.

Pair that with pigmented foods, and you may increase your risk of staining. Products like wine, curry, soy sauce, and cherries have chromogens in them. This substance is responsible for their dark color, and it intensifies when it reacts with tannins.

How Do Tannins Affect Your Enamel?

Did you know that your enamel is porous? This means that there are tiny spaces that tannins are able to find their way into. They sit on your smile and attract chromogens, leading to the discoloration that you may know too well. Although staining can happen over time, tannins can intensify it, making you notice them a bit more.

What Can I Do to Whiten My Teeth?

You may wonder if you should cut out all foods and drinks that have these chemicals and substances in them. However, tannins are great antioxidants, so finding another way to get rid of the discoloration may be your best bet. Your dentist is here to help with professional teeth whitening. They use a high-quality bleaching agent that is leagues better than what you can find in stores.

With an in-office visit, your dentist will place the whitening gel on your smile while protecting your gums. The product dives deep into your enamel and breaks up the chromogens and tannins that are causing the staining. In about an hour, you will leave with results that are noticeably brighter!

If an at-home kit is more convenient for you, then your dentist may offer it as well! You will be given custom whitening trays with a professional-grade gel that you wear for a couple of weeks. After consistent use as directed by your dentist, you will have similar results as if you went for an in-office treatment.

Coffee, wines, and berries are tasty things that many people can’t part with. You shouldn’t feel that you have to cut them out completely! Instead, alternate sips of water while enjoying these items to lessen staining. You can also visit your dentist for an effective way to get back to bright pearly whites!
