Are Yellow Teeth Stronger Than White Teeth?

With the internet becoming the primary source of information, people often stumble upon misleading and confusing content. As dental professionals, we frequently encounter questions like “Are yellow teeth stronger than white teeth?” It is our responsibility to dispel dental health myths circulating online.

This article, backed by our expertise and years of practice, aims to clarify the misconception that yellow teeth are stronger than white teeth. This belief, whose origin is unclear, might refer to individuals who naturally have darker shades of teeth or follow certain practices leading to yellowish teeth. As experts, we will set this myth straight by answering, “Are yellow teeth stronger than white teeth?” and explaining what causes teeth to turn yellow in the first place.

Moreover, the colour of your teeth is determined by the natural or acquired colour of the different layers of your teeth and does not necessarily indicate their strength. Various factors can affect the strength of your teeth. In this comprehensive article, we will discuss the layers of your teeth, understand what causes them to turn yellow, explore the latest whitening treatments available, and address all your burning questions about yellowish teeth.

What Are Tooth Layers?

To answer whether yellow teeth are stronger than white teeth, it’s essential to understand the different layers that make up a tooth. This knowledge will help us recognize that whiter teeth do not necessarily indicate weaker teeth. Our teeth consist of four main parts, which are as follows:

• The Pulp: In the centre of the tooth, the pulp is an essential living layer of blood vessels and nerves. It makes the soft tissue of the tooth and the foundation layer. 
• Dentin Layer: The dentin is the middle layer of the tooth that surrounds the soft tissue of the pulp. It is a living tissue, but unlike the pulp, it is calcified and harder. The dentin layer protects the pulp and is a foundation for the enamel. The dentin layer’s colour determines the tooth’s colour, as the outer layer (enamel) is almost translucent. You will have yellowish teeth if you have a darker shade of dentin. 
• Enamel and Cementum Layer: These are the outer layers of the tooth that differ in location. Enamel covers the dentin in the crown area, while cementum covers the dentin in the root part.

Are yellow teeth stronger than white teeth?

The straight answer is no. However, we should distinguish between the strength of the tooth and its color. Yellow teeth are not stronger than white teeth and could be weaker. When the tooth enamel layer attains a darker shade, it could be an early indication of weakened enamel or another dental issue.

The strength of our teeth is influenced by various factors such as genetics, dental care practices, general health, and diet. These factors affect the enamel layer’s color, strength, and sensitivity to cavities and decay. Similarly, the color of your teeth is determined by the color of the dentin layer, which genetic and non-genetic factors can influence.

If you notice that your teeth are changing in color or turning slightly yellow, you should prioritize seeking professional dental advice as soon as possible. Taking preventive action at this stage can help avoid the need for more extensive treatments or interventions later.

What Causes My Teeth to Turn Yellow?

After addressing the central question of this article, “Are yellow teeth stronger than white teeth?” it would be logical to address what causes teeth to go from bright white to slightly yellow or darker shades of yellow. Below are the most common causes of tooth yellowing and discoloration:

1. Diet: According to a study in the Journal of the American Dental Association (JADA), certain foods and drinks, such as coffee, tea, soda, alcohol, and some fruits and vegetables, can cause your teeth to become a light-yellow shade.
2. Tobacco Products: Tobacco and non-tobacco heated products cause teeth staining and discoloration, as a 2023 study on the National Library of Medicine website indicates.
3. Poor Oral Hygiene: Poor or no brushing and flossing practice and not using mouthwash are highly associated with tooth yellowing.
4. Aging: As we age, the outer layer of enamel on our teeth gradually wears away, which can lead to the exposure of the natural yellowish color of the dentin underneath.
5. Injury or Trauma: Severe injury or trauma can cause teeth to change color due to damage to the enamel and nerves, leading to discoloration.
6. Medical Conditions: Certain diseases and treatments can cause tooth discoloration by affecting the enamel and dentin layers. For instance, head and neck radiation and chemotherapy can lead to teeth discoloration.
7. Fluoride Exposure: Excessive fluoride in water or excessive use of fluoride products like toothpaste and mouthwash can cause teeth discoloration.
8. Medications: Certain medications, like tetracycline and doxycycline, can cause tooth discoloration in children. Chlorhexidine mouth rinses, certain antihistamines, antipsychotic drugs, and high blood pressure medications may also lead to tooth staining or yellowing.
9. Genetics: Some people inherit brighter or thicker enamel. If your parents have a bright white smile, you’ll likely have one, too, and vice versa for yellowish teeth.

Teeth Whitening Treatment

As you’ve learned, yellow teeth are not necessarily stronger than bright white teeth; it can be the opposite. Now, we’ll discuss teeth whitening treatment. Before that, it’s important to note that several factors must be considered when choosing the appropriate teeth whitening plan for each patient. These factors include the severity of the discoloration stain, the patient’s budget, and their commitment to the treatment. A cosmetic dentist can help you determine the most suitable method based on these factors. Below are the most common whitening treatment methods:

• Professional in Clinic Teeth Whitening Treatment

During a clinic tooth-whitening session, the dentist begins by noting the current shade of your teeth. Polishing removes plaque. To keep teeth dry, dentists isolate the mouth and use a gumline barrier for protection. They apply a whitening solution, often with hydrogen peroxide or carbamide peroxide, to the teeth’s front surface and rinse it off after 30 to 60 minutes. Sometimes, laser or light agents enhance results. Dentists may apply fluoride to reduce tooth sensitivity. They might schedule more visits depending on the staining severity.

• Veneers (Hollywood Smile)

Veneers are thin shells made of porcelain or composite resin that are custom-made to fit over the front surface of teeth. They are a widespread and long-lasting solution for various dental issues, including discoloration, decay, and staining. Veneers effectively cover imperfections and provide a durable, resilient solution, giving patients a natural-looking and bright white smile. In essence, veneers act as a versatile solution, offering aesthetic enhancement and functional improvements in the appearance of teeth; they can effectively cover up imperfections such as chips, cracks, and gaps, thereby restoring the more natural bright white smile.

• Whitening Trays and Gels

Teeth whitening trays and gels, Dentist-provided kits use stronger peroxide for faster, more efficient whitening, while custom-made trays ensure a perfect fit, reducing the risk of gum irritation. However, avoiding over-the-counter whitening trays and gels is advisable to reduce the risk of triggering tooth sensitivity, harming the enamel layer, or, even worse, causing gum irritation.
