Yellow teeth are generally described as a loss of the natural whiteness of the teeth. Sometimes, genetic factors can cause a person’s natural tooth color to lean towards yellow. Other times, changes in the color of the teeth can occur due to various reasons, and the most common of these changes is yellow teeth. Of course, yellow teeth are not a desirable appearance and can cause significant discomfort for a person.
It is actually normal for the color of the teeth to change slightly over time. As time passes, teeth may lose their brightness and whiteness, but when yellow teeth becomes more apparent, it may require intervention to restore their appearance. The primary cause of the color change in teeth over time is the thinning of the enamel layer, which allows the underlying dentin layer to become more visible. Since the dentin layer is darker than the enamel, the teeth have a yellowish appearance.
Yellow teeth can be addressed, and methods such as teeth cleaning or whitening can lead to successful results. We will discuss in detail which methods can be used and the causes of yellow teeth. But first, it is useful to briefly review the types of tooth discoloration.
Types of Tooth Discoloration
Generally, there are two main types of tooth discoloration, both of which can result in yellow teeth. The types of tooth discoloration are:
External Discoloration
External discoloration refers to changes in the tooth’s outer surface. This discoloration is usually caused by food and drinks. Methods such as teeth whitening can largely eliminate staining.
Internal Discoloration
Internal discoloration affects the dentin and enamel layers of the tooth. Tooth trauma, enamel erosion, or certain medications can cause this type of discoloration.
Preventable Causes of Tooth Discoloration
There are several reasons why yellow teeth may develop, some of which can be categorized as “preventable causes of tooth discoloration.” These causes can be summarized as follows:
- Consumption of foods and drinks that cause staining, such as tea, coffee, certain fruits, red wine, and soy sauce
- Use of tobacco products
- Lack of oral and dental hygiene
- Excessive fluoride application
These are factors that individuals can avoid, making them preventable causes of tooth discoloration. By staying away from these elements, it is possible to prevent changes in tooth color.
Unpreventable Causes of Tooth Discoloration
Of course, some reasons for tooth discoloration are beyond a person’s control, and these can lead to unwanted changes in tooth color, such as yellow teeth. Unpreventable causes of tooth discoloration include:
Genetic Factors
One of the factors that determines the natural color of teeth is genetics, and this is why genetic factors are included among the unpreventable causes of tooth discoloration.
Dental Trauma
A heavy blow to a tooth can cause dental trauma, which can lead to a change in the tooth’s color. Thus, dental trauma can occur due to factors beyond a person’s control.
Aging
As a person ages, the enamel layer of the tooth thins, leading to the tooth taking on a yellowish hue as the dentin layer becomes more visible. This process can contribute to the problem of yellow teeth.
Dental Treatments
Tooth discoloration is not always yellow; sometimes, a grayish color may appear. One reason for this is the use of amalgam in metal dental fillings.
Certain Diseases
Some diseases significantly affect the color of teeth. These include liver conditions, celiac disease, calcium deficiencies, eating disorders, and some metabolic diseases.
Certain Medications
Certain medications used to treat various conditions can lead to yellow teeth or other color changes in the teeth. Most of the time, these changes are temporary and disappear once the medication is stopped, but in some cases, the discoloration can be permanent.
Cancer Treatments
Chemotherapy or radiation therapy used in the treatment of cancer can also cause changes in tooth color.
How to Prevent Yellow Teeth?
If you don’t want to experience the problem of yellow teeth, there are some important precautions to take. The answers to the question “how to prevent yellow teeth” are as follows:
- Never neglect oral and dental hygiene, and make sure to brush your teeth twice a day using the correct technique.
- Clean the spaces between your teeth and the tooth surfaces with dental floss once a day.
- Limit the consumption of drinks like tea and coffee, which can stain teeth.
- After consuming foods or drinks that can cause staining, make sure to clean your teeth.
- Avoid using tobacco products.
- Be sure to visit the dentist for routine check-ups every 6 months.
What Causes Yellow Teeth or Discolored Teeth?
There are many reasons why teeth may change color or become yellow. Some of the most common causes include:
Enamel Erosion
While the enamel layer of the tooth is very hard, it can erode due to various factors. The erosion of the enamel, which is the protective layer of the tooth, leads to the loss of the tooth’s natural shine and a more yellow appearance. Eroded enamel cannot repair itself naturally, so intervention from a dentist is necessary in such cases.
Genetic Factors
Genetics play a significant role in determining the color of your teeth. Some people may naturally have teeth that are closer to a yellowish color. The thickness or thinness of the enamel is also influenced by genetics, so it is a contributing factor to tooth discoloration.
Side Effects of Medications
Certain medications used to treat various conditions can cause changes in tooth color. Medications used by both children and adults may lead to stained teeth. Some mouthwashes or iron supplements can also cause such issues.
Use of Tobacco Products
The use of tobacco products is one of the most common causes of tooth discoloration worldwide. Tobacco can cause yellow teeth and brown stains, significantly affecting oral and dental health. Therefore, it is crucial to avoid using tobacco products.
Neglecting Oral Hygiene
Neglecting oral hygiene is a direct cause of tooth discoloration. In these cases, yellow teeth usually occur first, and plaque accumulates on the teeth and between them. Over time, plaque hardens into tartar, leading to brown or black discoloration. Neglecting oral care is one of the primary reasons for tooth discoloration.
Teeth Grinding (Bruxism)
Teeth grinding, or bruxism, is a problem many people experience, which can sometimes lead to tooth wear. This behavior, often occurring at night as teeth grinding, can cause small cracks in the enamel, making the dentin layer more visible and resulting in yellow teeth.
Diseases
Certain diseases can indirectly damage the enamel layer of the teeth, leading to discoloration. Liver diseases are a notable example of this.
Dietary Habits
Dietary habits are an important factor in determining tooth color. Excessive consumption of sugary or acidic foods and beverages can lead to enamel wear, which in turn changes the tooth color. Frequent consumption of food and drinks containing food coloring can also cause the loss of tooth whiteness.
Treatment Methods for Yellow Teeth
As mentioned earlier, yellow teeth can occur for many different reasons, and the most appropriate treatment methods are determined by a dentist based on the cause. Some of the most common treatments to eliminate staining of the teeth include:
Teeth Whitening
Teeth whitening is one of the most frequently used treatments for yellow teeth or discoloration. As part of cosmetic dentistry, teeth whitening not only eliminates discoloration but can also make teeth appear several shades lighter. Whitening treatments are generally offered in two types: in-office whitening and at-home whitening. For more effective results, in-office whitening, which is performed by a dentist, is recommended.
Dental Veneers
Sometimes, the reason for yellow teeth is internal factors, and whitening methods may not provide a satisfactory result. If yellow teeth or discoloration cannot be corrected with whitening treatments, dental veneers can be used. Veneers effectively cover the discoloration, allowing individuals to hide the stains. Especially porcelain veneers are highly preferred recently, as they provide a natural-looking dental appearance.
Methods for Whitening Yellow Teeth
The most effective way to overcome problems like yellow teeth or staining is teeth whitening. There are two main methods used today for teeth whitening, which are as follows:
Office Bleaching
Office Bleaching is a method that must be performed by a dentist. Bleaching agents are applied to the teeth by the dentist, and a special light is used to help the teeth whiten. Depending on the degree of discoloration, the duration of this procedure may vary, but it is generally completed within 20 minutes.
Home Bleaching
Home bleaching, custom transparent trays are made for the patient, and whitening agents are used to whiten the teeth. This method is applied by the individual at home, with instructions from the dentist on how to use it. Whitening agents are applied to the transparent trays, and the trays are worn by the patient for 6 to 8 hours.
Home Treatments for Yellow Teeth
The only home treatment for yellow teeth is home bleaching method mentioned above. Other methods must be performed by a dentist. Using materials such as baking soda, lemon juice, certain herbal treatments, or over-the-counter products for home application can damage oral and dental health. Continuous use of baking soda, for instance, can lead to gum diseases, so it should be avoided. If you have yellow teeth, visiting a dentist is the best choice.
