Having a bright, beautiful smile is something most people desire. Unfortunately, daily activities like eating and drinking certain items with tannins can lead to stained teeth. Though you can visit a dentist for teeth whitening services, it's important to know how to maintain your smile between appointments. Consult the guide below to learn about tannin and how it affects your teeth's appearance. 

What Are Tannins?

Tannins are organic compounds that give certain foods their bitter taste and color. When consuming tannins, the compounds will interact with sugars, proteins, carbohydrates, and enzymes in the mouth. They also interact with bacterial cell membranes. 

Bacteria, sugar, and proteins naturally stick to enamel, the outermost layer of a tooth. Since tannins interact with them, the compounds will also adhere to teeth, leading to discoloration and possibly dental decay and cavities. 

What Are Common Foods and Beverages With Tannins?

Because tannins are bitter, you will likely find them in acidic beverages and foods notorious for causing stains. Examples include cherries, red wine, soy sauce, colas, coffee, tea, and curry. Because of the acidity of these items, they can soften and erode tooth enamel, creating rough patches that make it easier for the tannins to stain the teeth. 

Many of these items contain chromogens or substances converted into dyes or colored compounds. Tannins and chromogens create a reaction that intensifies discoloration. 

How Can You Avoid Discoloration When Consuming Tannins?

Your dentist likely won't tell you to abstain from all tannin-rich foods and beverages. You can take steps to minimize tooth discoloration and enjoy the drinks and meals you love. For instance, you can enjoy coffee or tea with cream or milk to weaken the tannins without dramatically downgrading the taste of the coffee beans. 

Another tactic is to rinse your mouth after enjoying tannin-rich drinks or foods immediately. Rinsing prevents many of the tannins and other debris from settling on your teeth. It's also a good idea to keep your bi-annual dental appointments. Your dentist will examine and clean your teeth, reducing the risk of severe discoloration or decay.
