8 Foods and Drinks That Stain Teeth

Blueberries, coffee, sodas… Watch what you eat! Many foods and drinks can stain your teeth. Zoom on the most harmful for your smile with the explanations of Dr. Christophe Lequart, dental surgeon and spokesman for the French Union for Oral and Dental Health (UFSBD).

1 – The coffee

Coffee tends to stain the surface of the teeth because of the caffeine and tannins it contains. Tannins are vegetable substances from the polyphenol family that stain the enamel.

How do stains appear? “Stains that are related to diet or certain lifestyle habits are part of what is called external stains. They are deposits that will be made on the surface of the tooth and will then penetrate the enamel if there are cracks,” explains Dr. Christophe Lequart, dental surgeon.

2 – Soft Drinks

Some sodas like Coca-Cola® or Pepsi® tend to stain the surface of the teeth because of the caramel colouring and caffeine they contain.

Tip: “As soon as you have eaten or drunk something that can stain your teeth, you should rinse your mouth with clear water or, at the very least, drink a glass of water to remove some of the tannins that have settled on the surface of your teeth,” says the specialist.

3 – Red wine

Red wines tend to stain the surface of the teeth because of the tannins they contain. Most of the tannin in red wines comes from the grapes used to make the wine.

Scaling is the key: “These stains on the tooth surface can be removed by scaling and polishing in a dental practice,” explains the specialist.

4 – Tea

Teas, both black and green, tend to stain the surface of the teeth because of the theine they contain. Tea contains a lot of tannins, even more than coffee.

Tip: “If you rinse your cup immediately after drinking your tea, the deposits can be easily removed. If you wait 30 minutes before rinsing your cup, to be able to remove these theine deposits from the cup, you will have to rub! It is exactly the same thing that happens on the surface of your teeth” explains Dr. Christophe Lequart. So don’t hesitate to rinse your mouth with clear water or drink a glass of water after drinking.

5 – Soy sauce

Soy sauce tends to stain the surface of teeth because of the tannins it contains and to aggravate the porosity of teeth because of its acidity.

Namely: “It is recommended that you brush your teeth immediately after consuming the food or drink containing tannins. Brushing will remove deposits from the tooth surface. The electric toothbrush is better at erasing surface discoloration than the manual toothbrush. Brushing will make it possible to eliminate a part of these surface stains but will also make it possible to reduce their installation after a scaling” explains Dr Christophe Lequart.

6 – Curry

This spice originating from India tends to stain the surface of the teeth. Whether it is yellow, red or green, curry causes discoloration.

How to remove stains? “Bleaching or tooth whitening does not affect external stains but the tooth’s own color. Food and drinks containing tannins will not influence the clean color of the tooth but only the stains. Bleaching is therefore not the solution to this problem, we have to turn to scaling” explains Dr. Christophe Lequart.

7 – Beetroot

Beets tend to stain the surface of the teeth.

Tip: “As soon as you have eaten or drunk something that can stain your teeth, you should rinse your mouth with clear water or, at the very least, drink a glass of water to remove some of the tannins that have been deposited on the surface of your teeth,” says the specialist.

8 – Red fruits

Red fruits such as blueberries, blackberries and blackcurrants tend to stain the surface of the teeth because of the tannins they contain.

Tip: “To remove these external discolorations, a cleaning is necessary once a year,” says the specialist.
