Attention Tooth discoloration: These 7 foods discolor our teeth

Bright white teeth – that’s what many people want. However, they are often unaware of which products are responsible for their discolored teeth. Because: Some foods sound harmless, but are actually the cause of yellow teeth. Learn here which seven foods you should avoid if you want to shine with a white, radiant smile.

Tooth discoloration: what is it??

With tooth discolorations, a distinction is made between inner and outer tooth discolorations. The expert calls these then extrinsic or intrinsic tooth discoloration.

For black teeth, there are many different causes, so the treatment should be tailored to the individual patient. Whether a professional tooth cleaning, a bleaching or a ceramic veneer again ensures a white smile, you will find out in conversation with your dentist.

Discolored teeth are today easily treatable with modern technology.

Extrinsic tooth discoloration

These stains arise on the tooth surface and have external causes: Dyes from certain foods, tobacco or medicines accumulate there. Lack of oral hygiene can also be a cause: If the plaque is not removed regularly, it will mineralize. The result is yellowish tartar, which can not be removed by the domestic dental care.

External discoloration can be solved easily and quickly by a professional tooth cleaning. The prophylactic aid removes dark spots with ultrasound and with certain polishing paste and brush.

Intrinsic tooth discoloration

Internal discolouration can be caused by color deposits and structural changes. This can lead to amalgam fillings, metabolic diseases or certain medications. But also an incipient caries, which can be mineralized again by good care, will later be visible as a black tooth discoloration. When minerals re-deposit, dyes can become embedded in the tooth and discolour it. The “healed” tooth decay is then seen as a dark spot.

Internal discoloration is more difficult to treat than external: Proper brushing or a thorough cleaning of the teeth at the dentist are then powerless. In some cases, bleaching can help, but it should be done professionally. Very stubborn stains can only be covered by plastic fillings or ceramic veneers.

7 foods that discolour your teeth

The fact that coffee and black tea discolour our teeth is well known. But there are some other foods that you have not known to cause severe tooth staining.

Acidic fruit juices

Acidic drinks such as orange juice or tomato juice attack our enamel and lead to discolored teeth. Due to the acid contained, the tooth enamel is roughened first. Dyes from the juices can then be stored more easily. As these juices also contain a lot of sugar, the risk of tooth decay increases. Carious defects are ultimately also recognizable by dark areas. These internal discolorations can not be completely removed even by professional tooth cleaning.

Red and white wine

Alcohol also leads to tooth discoloration. Especially the intense colors of red wine discolour your teeth strongly. The acidity of the wine roughens the tooth surface, making the surface particularly receptive to the color segments of the wine.

If you want to use white wine now because of the less intense color, you make a mistake: Scientists have found that white wine causes even more discoloration than red wine. Because white wine dissolves more calcium from deeper layers of teeth than red wine and thus leads to intense discoloration despite the stronger color of red wine.

Balsamic vinegar

Balsamic vinegar is very popular as a dressing for salads and is used in many dishes.

But beware: The dark dyes can cause spotty discoloration, while the acidic vinegar also attacks our enamel and, when consumed frequently, leads to dental erosion. This loss of tooth hard tissue increasingly weakens the stability of the teeth and leads to hypersensitive tooth necks.

Therefore, be sure to limit the consumption of balsamic vinegar and resort to alternative dressings (such as yoghurt dressing).

Soft drinks like Cola, Fanta and Co.

Sweet soft drinks such as cola or fanta are considered a special refreshment. However, most of these drinks are extremely acidic and thus harm the dental substance. The high sugar and dye content lead to yellowish tooth discoloration and damage your teeth. And ice tea leads to discoloration – but not yellowish, but brownish. It is made from black tea and the black color pigments stick easily to our teeth.

NoteExcessive consumption of sugary soft drinks can lead to dental diseases such as tooth decay or periodontitis. Drink soft drinks therefore only in moderation.

Spices like curry or saffron

Spices such as curry, saffron or turmeric are used especially in Asian cuisine. These spices leave a color film on our teeth due to the high number of pigments.


Smoking leads to yellowish discoloration and deposits on your teeth, as permanent dyes are left behind. The more you smoke, the greater the extent of discoloration. In particular, the tobacco smoke contains substances that also lead to brownish discoloration.

Basically, the consumption of nicotine is responsible for numerous general diseases. The circulation in the mouth is worsened and the immune system is reduced. The type of bacteria in the oral cavity also shifts towards harmful microorganisms. Often a disease of the periodontium is the result: periodontitis leads to bone loss and later to tooth loss.

Chemical chlorine water

Although it is not a food, it nevertheless carries the risk of discoloring your teeth in everyday life: Chlorinated water. When you swim in conventional swimming pools with chlorine water, water often gets into your mouth. As a result, chemicals penetrate your teeth. Chlorine has a low Ph value: the acid attacks the tooth enamel. This leads to unwanted yellow discoloration and tooth damage.

Note: An occasional swimming pool visit is safe for your teeth. However, swimming several times a week for several hours may have a negative effect on your teeth.

Tooth discoloration? The solution: professional teeth whitening

You are dissatisfied with your tooth color and want whiter teeth? A professional whitening with your dentist provides a whitening. An alternative method is veneers. Here, thin ceramic shells are glued to the natural teeth and make your teeth look whiter.
