6 Foods That Might Stain Your Teeth

by Kar Yan | 22 Jan 2018

Who wants stained and discolored teeth? A bright smile can make you more confident and definitely leave a good first impression. Even though teeth darkening may occur as you age, but there are some foods and drinks that you consume daily may stain your teeth.

1. Coffee

Coffee contains tannins (acidic polyphenols) that will lead to staining and discoloration. The acidity of tannins will alter the pH balance of the mouth. It may cause teeth damage occur faster if you consume acidic food afterward. Research suggests that adding milk to your tea reduce its ability to stain your teeth.

2. Acidic Foods

If you notice a yellowish tinge to your teeth, acidic foods such as citrus fruits, tomato and berries may cause them. Even though they are full of nutrients, but these fruits can destroy the enamel (the surface). It will expose the slightly yellow teeth as the beneath are made up of of calcium and phosphate crystal.

Besides that, the deep hue in those berries that are packed with antioxidants may stain your teeth. Therefore, it is important not to let the berries linger around in the mouth for a long period of time and also make sure to drink water after that.

3. Beetroot

Just like how beetroot stain our hands, it can also stain your teeth.

4. Carbonated, Energy and Sports Drink

These drinks not only have high acid content, they are also high in sugars. It will give bacteria in your mouth to feed off (and thus releasing damaging acids) which will lead to cavities. Drink lesser or look for natural alternatives!

5. Wine

Just like coffee, wine also contains teeth-staining tannins. Both red and white wine are hard on our teeth BUT white wine is more acidic. Therefore, drinking white wine may cause your teeth to be stained from those foods you are eating at that time.

6. Tea

Tea also contains natural staining compound known as tannins. Compared to coffee, black tea will stain your teeth even worse as it contains more tannins which will stick to your teeth as they are attracted to the protein in enamel. Green and white tea have lower in tannins but they still do stain your teeth a little if you do not practice regular brushing and flossing. Green tea contains fluoride which is responsible to make our teeth whiter and stronger. Just don't forget to maintain your oral hygiene.

In addition, research suggests that adding milk to your tea reduce its ability to stain your teeth.
