Even casual food and wine lovers have likely heard of tannins, the compounds that give food and beverages their color and hint of bitterness. You may have heard some praise them and some avoid them, but what are they really about? Here is a brief guide to tannins and why you should be mindful if you are whitening your teeth or having issues with cavities. 

What Are Tannins?

Tannins are a group of organic compounds that interact with the enzymes, proteins, sugars, and bacteria inside the mouth.  The teeth are covered with a protective coating of enamel, but the enamel is quite porous. Tannins stick to this enamel, attracting sugars to the teeth which can lead to cavities and staining. 

What Are Some Foods and Beverages That Contain Them?   

Tannins occur naturally in certain pigmented foods and beverages. Drinks such as coffee, soda, tea and red wine, and foods and spices such as cherries, soy sauce and curry are leading culprits of tooth discoloration due to their intense colors and tannin makeup. 

A general rule is that if the substance could stain a white shirt, it can stain teeth. Tannins react with other compounds in these foods to increase their staining effects.  

How Can You Avoid Discoloration?

Despite their staining effects, tannins are actually good antioxidants. Even if you could avoid them altogether, it isn't advised. Instead, just rinse your mouth with water or mouthwash after you have consumed food or beverages with tannins. 

Stay on top of brushing, flossing, and dental cleanings to fight both cavities and stains. Let your dentist know of any changes or concerns about your oral health. Also, consider adding milk or creamer to your coffee as the enzymes in those products can help weaken the tannins.
