Why Are My Teeth Yellow Even Though I Brush Every Day?

Good oral hygiene habits are an important part of maintaining a bright and radiant smile. However, brushing your teeth may not always be enough to prevent tooth discolouration.

A wide range of factors can contribute to yellow teeth. These factors may include things you cannot control, such as age or genetics, and things you can control, such as vaping or dietary habits. 

Learning about what causes yellow teeth and what you can do about tooth discolouration can help you make the right decision about cosmetic dentistry and other treatments you may want for your teeth. 

What Causes Yellow Teeth? 

We often associate yellow or discoloured teeth with poor dental hygiene, but that is not always the case. While poor dental hygiene can contribute to tooth discolouration, it is just one of many factors that can cause yellow teeth

Some of the other factors that can cause tooth discolouration include: 

  • Genetics
  • Enamel erosion and age
  • Dietary habits
  • Tobacco use and vaping
  • Poor dental hygiene

Genetics

First and foremost, it is essential to recognize that the natural colour of your teeth can vary from person to person. Some individuals naturally have whiter teeth, while others have slightly yellowish or grayish teeth. This can be influenced by genetics, as well as the composition and thickness of tooth enamel

Despite regular brushing, the underlying natural colour of your teeth may still have a yellow tint. However, that does not necessarily mean your teeth are not healthy, and maintaining good oral hygiene practices can still help your teeth remain bright and strong. 

Enamel Erosion & Age

As we age, the outer layer of our teeth, known as enamel, can naturally wear down, revealing the yellowish dentin underneath. Enamel erosion can be accelerated by factors such as excessive consumption of acidic foods and drinks, acid reflux, and certain medications. As your enamel becomes thinner, your dentin’s yellow hue can become more visible. 

Fluoride can be beneficial for preventing enamel erosion, as it can actively help strengthen your teeth. Many dental hygiene products contain fluoride, including some toothpaste and mouthwash. If you suspect you may be experiencing enamel erosion, you should consult your dentist for appropriate treatment options. 

Dietary Habits

The foods and beverages you consume regularly can have a significant impact on the colour of your teeth. Dark-coloured substances such as coffee, tea, red wine, and certain fruits like berries can stain your teeth over time. Additionally, highly acidic foods and drinks can erode your enamel, revealing the yellowish dentin layer beneath. 

While brushing your teeth after consuming these foods or drinks is not always feasible, rinsing your mouth with water can help minimize the staining effects. It is also a good idea to limit your intake of these staining substances and incorporate more teeth-friendly foods into your diet. 

Tobacco Use & Vaping

Smoking or using other tobacco products can cause discolouration of your teeth. The chemicals present in tobacco and tobacco smoke, such as tar and nicotine, not only stain your enamel but can also contribute to the overall deterioration of your oral health. Over time, these stains can become deeply ingrained and harder to remove. 

While they do not always contain tobacco, vaping products can also cause tooth discolouration. Quitting smoking, vaping, and other forms of tobacco use can be beneficial not only for your overall health but also for maintaining the whiteness of your teeth. 

Poor Dental Hygiene

Although you may brush your teeth daily, it is possible that your technique may not be as effective as you think. Brushing too vigorously may cause enamel erosion, leading to yellowish teeth. On the other hand, not brushing enough may not effectively remove surface stains. 

In order to maximize the benefits of brushing, it is important to follow proper technique and use a toothpaste that contains enamel-protecting fluoride. 

How to Treat & Prevent Yellow Teeth

While a regular brushing routine is crucial for maintaining good oral health, it is important to understand that brushing alone may not always be sufficient for achieving a white smile. 

To combat yellow teeth, it is essential to adopt a holistic approach to oral care. 

Some additional steps you can take include: 

  • Regular dental cleanings: Professional dental cleanings can help remove stubborn stains and tartar buildup that brushing alone cannot address. Schedule regular visits with your dentist for cleanings and checkups
  • Whitening toothpaste or mouthwash: Consider using dental hygiene products that contain a whitening agent. These products can help remove surface stains and restore the natural whiteness of your teeth. However, it is important to use them as directed and avoid excessive use, as they may cause tooth sensitivity or enamel damage. 
  • Professional teeth whitening: If you are looking for a more robust tooth whitening option, you may benefit from a professional teeth whitening treatment. We can recommend an appropriate whitening procedure based on your needs and dental health. 
  • Good oral hygiene: Brushing your teeth twice per day and flossing daily can remove plaque and bacteria to help promote overall oral health and maintain the whiteness of your teeth. 

Achieving and maintaining white teeth can be a gradual process. It requires consistency, patience, and a comprehensive oral care routine. If you have concerns about the colour of your teeth or need personalized advice, feel free to reach out to us.
