Do you want to keep a radiant smile and show teeth without spots? Check those things that you do every day and that you are not aware that your teeth may be yellowing.

There can be many reasons. With the passage of time the tooth loses its whiteness as the outer layer weakens, the enamel, which, when transparent, reveals the layer underneath, the dentine, which has a gray-yellow colour. But, in addition, we tell you many habits that we repeat day after day that can also stain our teeth and make them yellow.

Remember that if you have any type of problem with your teeth, you should visit Parkwood Green Dental, here we will help you with that.

Cleaning too aggressively

Too aggressive brushing with a very hard bristle brush or the use of an inadequate mouthwash or more times than necessary, can damage the enamel and make your teeth look yellow ahead of time. Be careful with mouthwashes with chlorhexidine, whose regular use can stain the teeth. It is preferable to get a dental hygiene more often than an intensive use of these rinses.

How do you wash your vegetables?

If you do it with vinegar, be careful because the acid damages the enamel. And if you use a sweeter vinegar, like Modena, or a sauce, like soy, you can color your teeth. Ideally, do not go over these dressings and, after the meal, wait about 15 minutes to brush your teeth. As a general rule, it is not convenient to wash your teeth just after consuming acidic foods, but wait a little while to avoid damaging the enamel.

Coffee with milk or without milk

Short coffee stains teeth less because its tannins remain less in the mouth. Even so, it is better to take a little and rinse your mouth with water afterwards. And even better if you drink it with milk, because according to a study published in the International Journal of Dental Hygiene, casein, a protein in milk, “sticks” to the tannins and drags them, avoiding stains, which would act, according to the researchers, with a “bleaching” effect.

Lemon juice

It is a very acidic drink and the acids trigger a chemical reaction in the enamel that makes it yellow. In addition, it weakens it because it also affects the calcium of the tooth. If you drink water with lemon to have a detox effect, you can replace it with an infusion such as horsetail, which is not aggressive with the teeth.

Food that spills your teeth

As a rule, if a food stains your clothes, it can stain your teeth. For example, blackberries or cherries can be used, which are highly pigmented foods, but also vegetables such as spinach or artichokes. And it is not wisdom to be at home, but there are studies on this, such as one from the University of Zagreb (Croatia) who found that patients with spots on the teeth used to eat more beets. But do not be alarmed, you should not give up eating these foods, just brush after eating them.

The tea (not only black) also ties the teeth

Black, but also red, contain tannins that stain tooth enamel. In addition, they are drinks that do not drink in a sip, but being long, they spend a while in the mouth, with which their ability to tint their teeth is greater. To avoid giving up your benefits, which are many, rinse yourself with tap water after drinking a cup of tea.

And the wine (yes, the white wine also)

The white wine does not dye as much as the red wine -which contains many tannins, a substance that stains the teeth a lot- but it is as acidic as this one, and this acidity is what makes its consumption can damage the enamel and make it more porous and prone to dye in contact with colouring substances. For example, it has been proven that coffee stains more teeth if taken after a glass of white wine.

Carbonic and sugar drinks

Carbonic acid erodes the enamel. And what about sugar, which not only attacks the enamel but increases the risk of decay. But … to avoid great damage, it is best not to abuse and drink these drinks with straw, so they have as little contact with the denture as possible. Of course, always afterwards you have to brush.

Candies not only cause cavities

The sugar attacks the enamel and can cause cavities but … it can also dye it, because the vivid colours that make caramels so attractive, for example, are nothing more than food colours.

We like white teeth. They are a symbol of youth, health and make our smile radiant. But … do you smile the same if you have yellow teeth? Surely not. To maintain a white and radiant smile and avoid stains on your teeth, check your habits, because teeth can turn yellow because of things you usually do, such as the fruits or vegetables you eat, the drinks you drink or the way you wash your teeth …

Why you have the yellow teeth

The teeth are not a nuclear target, it would not be natural. But it is true that with the passage of time, the natural white colour, which is very determined by the inheritance, goes off for various reasons, but basically because the enamel, the outer layer of the tooth, is worn and shows the layer that has just below, the dentine, which is grayish yellow.


But there are also everyday habits such as tea or coffee or water with lemon, to give an example, which make your teeth yellow and we tell you in the gallery. But, to make a summary, keep this in mind:

  • Avoid very acidic foods, such as citrus, vinegar …
  • Also, very sugary foods or drinks.
  • And those who can “dye” because they are very pigmented, like beets or blackberries, tea, coffee, wine, etc.
  • Maintain a good dental hygiene, but without exaggeration, because a too intense brushing or a very strong mouthwash, can damage the teeth.

The yellow teeth of children have a lot to do with having taken certain medications when they are small and the teeth are forming.
