Las 5 causas de los dientes amarillos

The 5 causes of yellow teeth

Surely you have always wondered why your teeth turn yellow. We explain the 5 reasons that cause this aesthetic problem.


We start with the best known, food. And there are certain foods that cause the pigmentation of our enamel, the archenemies such as coffee, tea, wine and although it is not a food, tobacco.

But at this point we also want to mention foods that contribute to an improvement in our health and dental aesthetics.


Both cheese and other dairy products, such as yogurt or kefir (which is also a good source of probiotics, beneficial for the intestinal macrobiota), can help maintain the white tone of the teeth. This is because they are foods rich in calcium and phosphorus, two components that adhere to tooth enamel and help neutralize the acid in saliva.



"Although it is a dark-colored food and we might think that it can stain the teeth, strawberries contain an enzyme known as malic acid, which makes the teeth whiter," they point out from the Adeslas Dental Clinic. Cherries, apricots, tomatoes, apples or plums are also rich in this acid, which is essential for dissolving stagnant bile and softening stones, in addition to promoting saliva production.



“Both apples, cucumbers and carrots, when consumed raw, contribute to cleaning the tooth surface,” says Bratos. In this sense, a good ally can be apple cider vinegar, which also has antiseptic properties, but you must be very careful with its use and not abuse it, as it can be counterproductive. Therefore, while it is true that the consumption of apple cider vinegar can help reduce stains and whiten the enamel, it is also true that its acetic acid content can end up damaging the pieces. This has, on the one hand, proven antiseptic and disinfectant properties, but on the other hand, being an acid, it can cause abrasions on the tooth enamel, making it more porous.

There are a large number of foods that contain color pigments . These foods wear out and can stain the color of the teeth in a very slight way. Some of them are coffee, wine or red fruits such as blueberries.


Lack of oral hygiene is one of the biggest causes of yellow teeth. If we do not properly clean our teeth, the bacteria accumulated on them will crystallize and form a yellowish layer called tartar.

This layer of bacteria is known as tartar and, in addition, it alters the aesthetics due to its yellowish and brown tone if it lasts for a long time. Furthermore, over time this plaque solidifies and professional cleaning is necessary to remove it.

It is no longer just a matter of hygiene, there is a relationship between oral health and people's life expectancy.


Leaving aside tobacco, knowing that it is bad for our health, but also a disastrous friend for the whites of our teeth, there are other drugs that are harmful to dental health, that destroy the tooth tissue and that excessively damage the teeth.

On the other hand there are medicines, which sometimes we have to take no matter what. We will comment on two, one not widely used today and another very common in oral care products.

Tetracyclines , very popular in the 60s and 70s, which cause severe darkening of the enamel, forming horizontal lines on the teeth

Chlorhexidine, a famous bactericidal and fungicide antiseptic, widely used to treat small wounds to prevent future infections. But, this stains the teeth a dark color.


Like all the cells in our body, they naturally age. Including teeth that darken as time goes by. This darkening occurs because food and tooth rubbing progressively weaken the enamel layer and cause the dentin to emerge (a darker color).

To do this, we recommend the use of products with FLUOR, a mineral that helps strengthen enamel and, as a consequence, prevent the appearance of cavities . Although you have to watch out for excesses. Excessive filtration can cause stains on the teeth or even damage the enamel, a disease called fluorosis.


As in so many other things, having a genetic tendency to have yellow teeth is also a possibility, although the first 3 points of the article will be of special importance.
