Early and concise answer to the question of the article.

The yellowing of the teeth, which may be very uncomfortable, can have two main causes.

  1. The first category is the causes that are not under your control and are unavoidable. such as genetics and ageing, and to get rid of them, one should resort to teeth whitening methods such as implants.
  2. The second category is the reasons that are caused by the lack of oral and dental hygiene or the presence of underlying diseases. This group of causes of tooth yellowing will be resolved by maintaining oral and dental hygiene or by trying to treat the underlying disease.

As it is clear from the explanation above, the first category of causes are the causes that cannot be resolved even with the observance of oral and dental hygiene such as continuous brushing. And maybe you get frustrated that you brush your teeth continuously but your teeth remain yellow.

In this article from drhealthandbeauty by Dr, Sanaz, we will first explain the main reasons for tooth yellowness despite frequent brushing, and then we will provide practical and experienced solutions from whether it will be solved by brushing to choosing other practical methods to remove tooth yellowness.

By reading this article, you will get rid of your worries and by following the instructions, you will have an attractive smile. So let’s get started.

You should know before all the answers.

The question we must first answer is: what is the natural color of the teeth?
In response, we must say that the white and shiny appearance of the teeth is almost unnatural, natural teeth are usually yellow or gray in color. To better understand this answer, it is better to have a look at the anatomy of teeth:

On the outside, the tooth has a layer called enamel and its color is blue and white. But the enamel material is transparent, which allows to see the underlying layers, which is the dentin. 

Tooth dentin is yellower and darker in color, and this is what gives teeth a darker appearance.

Therefore, it is actually the color and thickness of the tooth enamel that determines the color of the tooth.

So even if you constantly brush and floss your teeth, but the color of your teeth is still yellow or not bright white, maybe the reason is the dark color of the dentin that is visible from under the tooth enamel.

Note: Sometimes, brushing too much and with a lot of pressure will make the tooth enamel thinner, and the tooth color will be darker due to the dentine color being visible.

If your teeth look yellow because of this, brushing will not whiten them, and you will have no choice but to use cosmetic methods such as dental lamination.

The root of yellow teeth

  • Unavoidable causes 

This group of reasons that cause yellow teeth even with a regular toothbrush are not caused by plaque and bacteria and include:

    • Genetics

      One of the most fundamental causes can be genetics

      • How to recognize that the yellowness of our teeth is genetic?

        There are some signs by which you will know that the yellowness of your teeth may be genetic. Which include:
        1. If several family members, especially parents or siblings, show the same tooth color despite good oral hygiene, it can indicate a genetic component.
        2. People whose teeth color is genetically determined may notice yellowing from a young age, even before exposure to staining agents such as coffee, tea, or tobacco. This early onset of tooth discoloration, independent of external factors, is a potential indicator of genetic influence.
        3. If the dark color of your teeth is evenly spread over the entire tooth, it indicates that underlying genetic factors have affected the overall tooth pigmentation.
        4. Resistance to whitening attempts despite adherence to recommended protocols may indicate intrinsic factors, such as genetic variations in enamel structure or thickness.

      • Whitening solution for genetically yellow teeth:

        Whitening kits, toothpaste, and whitening mouthwashes can penetrate into the porous structure of enamel and oxidize pigment molecules, leading to a reduction in surface discoloration and, to some extent, improving the brightness of teeth in the long term. 

Professional whitening treatments performed by a dentist, such as veneers and laminates, remain the most effective option to whiten teeth that are genetically dark and yellow.

Note: Bleaching will not be effective in this regard. Because this method is used to remove stains on the surface of the teeth..

    • Aging

      As people age, tooth enamel undergoes natural decay and erosion. By weakening it, the underlying layer of dentin, which is yellow, is exposed. As a result, by eating and chewing a variety of foods, you will see changes in the color and yellowness of the teeth. The solution of genetic yellowness of teeth is also true in this case.


    • Taking certain medications:

      According to the studies, the use of some medicines causes yellowing of the teeth and the formation of layers in the teeth. As:


      • Can tooth yellowing caused by the use of drugs be removed by brushing?

        Unfortunately, the yellowing of teeth caused by using certain medications, known as intrinsic staining, usually cannot be effectively removed by regular brushing.

        Drug-induced internal staining is more resistant to removal because it affects the deeper layers of enamel, making it difficult for surface cleaners to penetrate and remove the discoloration. While regular brushing is essential to maintaining overall oral health and minimizing the accumulation of plaque and surface stains, it is unlikely to change the color of teeth affected by internal stains significantly.


      • whitening solution for yellow teeth caused by the use of medicine:

        For people experiencing medication-induced yellowing of their teeth, it is important to consult an experienced dentist to discuss appropriate treatment options.

        Depending on the severity of the staining and underlying causes, the dentist may recommend specialized whitening treatments such as professional teeth whitening, porcelain veneers, composite bonding, or other cosmetic procedures designed to remove internal stains and improve the smile’s appearance.


    • Excessive use of fluoride

      • Can tooth stains caused by excessive use of fluoride be removed by brushing?

        Excessive use of fluoride, a condition known as dental fluorosis, while mild cases of dental fluorosis may only appear as fine white streaks or spots on the teeth, more severe cases can cause coffee stains. or moles that may affect the overall appearance of the teeth. Brushing alone is unlikely to cure dental fluorosis or discoloration, especially in more severe cases.


      • What are the treatment options for severe fluoride stains?

        Treatment of dental fluorosis usually requires professional intervention and may include different treatment options tailored to the individual’s specific needs.
        It can be one of the following:
        1. Microabrasion.
        2. Composite bonding.
        3. Porcelain Veneers. 

    • Filling teeth with silver

      Sometimes, your dentist may use silver filling materials for your teeth for various reasons (this usually happens in molars that need strength more than beauty).
      In this case, brushing will not cause whitening and change the silver color of the filling. And if their color bothers you, you can ask your dentist to replace them with white material.

  • Causes that are our own fault

    • Five causes of yellow teeth that can be fixed 

If the cause of teeth discoloration is the appearance of the deep layers of the teeth, it will be a bit difficult to fix it and require aggressive measures in the teeth whitening clinic. 

But there are some other factors for yellowing teeth that can be prevented with the help of whitening products or diet modification, which include:

      1. Smoking, including the use of cigarettes and hookah
      2. Foods like tomatoes, pickles, spices, and berries
      3. drinks such as tea, red wine, coffee, and soft drinks
      4. Severe damage to the tooth: This can lead to the enamel breaking and expose the dentin (the yellow layer of the tooth) and toothache.
