Coffee drinkers, take heed: Your teeth may be impacted by your morning or evening routine.
Whenever coffee spills on anything, it stains it. This general principle also applies to your teeth.
A type of polyphenol called tannins, which are present in coffee. Coffee’s tannins enter your teeth’ pores when you drink it. Tannins make colourants stay on your teeth and have a yellowish look. One cup of coffee each day is all it takes to discolour teeth.
Coffee’s acidity can eventually erode the enamel, causing further stains. Red wine and black tea also have teeth-staining tannins.
How to prevent discolouration from coffee
- Drinking coffee through a straw can help you avoid this.
- Don’t drink your coffee black, add some milk. Milk’s casein clings to tannins to stop the tea from staining.
