8 Foods That Cause Yellowish Teeth


Having a white denture is synonymous with youth, as it is very normal that with aging the teeth lose their natural white tone.

However, there are some foods that can cause yellowish teeth prematurely, as some substances can stain the teeth and deteriorate their white enamel.

The enamel of the denture is the one that gives the white color and the underlying layer, called dentine, is yellow.

If the enamel is still almost intact and you notice that your teeth are yellow, some foods may be staining it.

    This is one of the foods that cause more yellow spots due to its characteristic dark color.
    The outer layer of the teeth is very porous and therefore easily absorbs this type of food and its color.
  • Tea
    Many consider tea to cause fewer stains than coffee, but some types of tea may yellow more than coffee.
    Tea contains substances called tannins, which stain teeth.
    The best thing in this case is to choose the teas that are of clear colors or to cut them with milk.

    Dark sauces such as soy sauce, used to season foods, can also cause that yellowish hue in the teeth.
    The rule says that if a food stains clothing or carpet, it can also stain teeth.
  • Tomato Sauce
    The tomato sauce that we like so much to eat spaghetti and other foods can also cause us the yellow tone.
    This is because it contains high concentrations of acid, which causes erosion and yellow teeth.
    The trick that many recommend to reduce its effects is to eat a spinach or broccoli snack first.
  • Blueberries
    Blueberries are one of the best health foods thanks to their high antioxidant content.
    However, because of their dark blue color they can cause stains that are more difficult to remove.
    It is recommended to rinse immediately after eating blueberries. A good trick is to brush with a little sodium bicarbonate and lemon after consuming them.
  • Beetroot or beetroot
    All of us who have consumed beets know that their intense color can also cause spots, especially when consumed in the form of juice.
  • Curry
    The red and yellow tones of powdered curry unfortunately also cause yellow teeth.
  • Red wine
    Red wine contains antioxidants and other substances such as resveratrol, which has great benefits; however, it is not as friendly to your teeth because of its dark tone.

Keep in mind!

In any of these cases, you can reduce the effects on your teeth with a good mouthwash immediately after eating.

However, sometimes brushing after eating can aggravate the problem, as some acidic foods can soften the enamel up to half an hour after consuming them.

In this case, it is ideal to wait at least one hour to rinse.
