You’re probably aware that certain foods and beverages, such as coffee and wine, are prone to staining teeth. What you may not know is that this is caused by tannin, a group of bitter and astringent compounds. While the discoloration left behind is strong, solutions like professional teeth whitening and adjusted eating habits can help bring the shine back to your smile. Learn more about tannins and how to combat them below. 

What Are Tannins?

Tannins are naturally occurring compounds that give the color and acidic or bitter flavor to many foods and drinks. When you consume them, they settle on your teeth. Tannins attract sugar, carbohydrates, proteins, enzymes, and bacterial cell membranes. These substances then stick to your enamel, increasing your risk of cavities and tooth decay.

What Foods & Drinks Contain Tannins?

Many highly acidic and pigmented foods and beverages contain tannins. Unfortunately, this combination enhances the staining effect. Acids break down tooth enamel and allow the tannins to discolor vulnerable teeth. 

Pigmented foods also contain a substance called chromogen, which reacts with tannins and deepens the color of stains. Some of the most common offenders include coffee, wine, tea, curry, and berries.

How Can You Prevent Discoloration?

Completely cutting tannins out of your diet wouldn’t be practical, but there are steps you can take to reduce their impact. For example, adding cream or milk to coffee and tea lightens the color of the drink and weakens the tannins. 

It is also recommended that you remember the foods and beverages in your diet that contain tannin, and always rinse your mouth or drink water after consuming them. If possible, brush your teeth afterwards as well. Remember to wait at least 30 minutes, as the acids will temporarily weaken your enamel, and brushing in this state could damage your teeth.

Be sure to schedule routine dental appointments every six months for an exam and thorough teeth cleaning. While you’re there, you can ask about teeth whitening options to remove the staining and discoloration already left by tannins.
