How Does Coffee Stain Your Teeth?

Your teeth is made of enamel, the hardest tissue in the body. Despite its hardness, enamel is, in fact, a porous material. It has millions of microtubules or pores that can harbor stains from food and beverages, producing a dark or yellowish shade. Coffee, in particular, is among the most common types of drink that can stain your teeth. Here’s how coffee can give your teeth a dark shade:

The Role of Saliva

According to the American Dental Association, saliva builds and manages the healthy mouth, including teeth and gums. It naturally removes waste products, rinsing the mouth from acquiring microbial invasions that cause staining. It follows that a lack of saliva could play a major role in teeth discoloration.

Dehydration

Since coffee dehydrates, the coffee drinker is not able to produce enough saliva in the mouth to naturally rinse off the coffee particles. Make it a point to stay hydrated with water, and rinse after drinking coffee to help keep your mouth from going dry.

Hygiene

Everyone should brush their teeth 2-3 times daily. To prevent further staining, try brushing your teeth after drinking coffee. The fluoride in toothpaste mineralizes enamel, strengthening it and halting stains. If this is impossible, drink water to rinse the mouth or chew a stick of sugar-free gum to trigger saliva production.
