Causes and treatments

Having bright white teeth it’s a matter of both beauty and health. Tooth enamel can be uniformly yellow or some pale stains only appear on certain parts of the tooth, which can be in different shades of yellow, brown and gray. Finding out the causes for yellow teeth will give us the right answers on why do teeth turn yellow.


Yellow teeth can have multiple causes. This may be intrinsic (from inside the tooth) or extrinsic causes (external factors).

Let’s see why do teeth turn yellow.


Often, the teeth turn yellow while we age. Even if a person is using a good toothbrush and floss, great toothpaste, and brushes his teeth frequently, over the years some yellow stains can infiltrate in the white protective layer of the teeth and enamel. Toothpaste can not penetrate so deep, and although teeth are still strong and healthy, the smile will not be the brightest.

Foods and drinks

Teeth stains may occur due to beverages and food that we consume. Most negative in effects are alcoholic beverages, tobacco, coffee, carrots, tea, and berries because these products contain pigmentation agents.

The tooth may be affected from the inside.

If someone has a tooth whose color is darker than usual, perhaps the tooth is damaged, as its nerve has been affected. In this case, it may be needed a more complex intervention on the tooth than a regular teeth whitening procedure.

Although bleaching can have a temporary effect, a tooth that has a different color from the others should be treated by a dentist.

Inappropriate treatment on childhood teeth.

Before the age of eight, children’s tooth enamel is still forming and therefore it is vulnerable to substances that might turn teeth yellow and that may persist in adulthood, too.

If children are receiving large amounts of tetracycline (antibiotic), their teeth may present splashes of color ranging from yellow-brown to gray-blue.

Secondly, children who swallow more fluoride (e.g. from toothpaste), can form a teeth disease called fluorosis that causes whitish spots or lines on the teeth.

Inappropriate teeth hygiene.

Not brushing your teeth at least twice a day could lead to dental plaque, which is at first a sticky colorless deposit on the teeth but eventually will form tartar becoming pale yellow or even brown.

Plaque is not only an appearance issue, but it is an environment for bacteria development and could lead to cavities, decays, gingivitis, or periodontitis.

Different methods for teeth whitening
