Curious to know what your teeth color suggests? Read on.


4 Teeth Colors and their Indications on Your Oral Health


1. Yellow Teeth 

Probably the most common teeth color, slightly yellow-tinted teeth indicate a strong and healthy tooth, as what Science Focus had found. Yellow is the natural color of the dentine underneath whereas the outer covering of the teeth called enamel has a natural hue of bluish-white. Since enamel has a translucent property, the slight shade of yellow underneath is revealed, resulting in an overall shade of light grey or light yellow in your teeth. 

However, excessive discoloration in the teeth might suggest even deeper problems of disease and tooth decay. Darker shades of yellow in your teeth normally mean that you’re pearly whites have been exposed to heavy staining. There are a lot of factors that cause discoloration of the teeth and below are some. 

Factors Leading to Dark Yellow-colored Teeth 

  • Food and Beverages

A long list of pigmented food and drinks, such as red meat, berries, tea, red wine, and many others, cause the fading of your teeth color from pearly whites to dark tints of yellow. You might find it a struggle to steer away from such common food favorites but frequent consumption of these will never do your teeth any good. 

  • Genetics

As you know, teeth colors have a wide array of shades and your genes play a big role in what shade you’ll be born with. Some are lucky to be born with lighter pearly whites while some inherit darker shades of teeth. Genetics also plays in the development of the enamel, from its strength to its reactive properties to staining and the formation of proper teeth. Some hereditary teeth disorders, such as dentinogenesis imperfecta, also cause the natural discoloration of the teeth. 

  • Age 

The discoloration of the teeth may be due to the natural and inevitable process of aging. As you grow older, the enamel that protects your teeth slowly wears out, causing the underlying yellow dentin to be more visible. 

2. Brown Teeth

Brown-stained teeth are far more severe than dark yellow-shaded ones. A brown color implies that you’re teeth have gone through excessive staining from dark yellow to brown or worst, to even dark tints of brown. These spots and stains are even harder to remove over a long period of time. 

Just like having yellow teeth, frequent consumption of colored beverages and food, genes and age also contribute to the discoloration of the teeth. But particularly for brown teeth, the top culprit is an unhealthy lifestyle brought by smoking. With repeated use, nicotine and tobacco products that contain staining particles will be absorbed by the tiny pores in your teeth. 

Brown spots on the teeth also suggest the build-up of plaque, leading to the formation of tartar. Over time, tartar or calculus becomes harder and more permanent that turning to professional remains your only solution in order to remove it. 

3. Blue or Gray Teeth

For some people, hues of blue or gray in their teeth might be the natural color of the teeth they’re born with. On the other hand, certain conditions may cause tooth discoloration and might be an indicator of a  dental problem caused by antibiotic exposure. 

Tetracycline is an antibiotic medication known to change the color of the teeth to bluish-gray. If you have been exposed to this substance at an age as early as when you were in your mother’s womb, chances are, you will acquire blue or gray-stained teeth. Normally the stains create horizontal patterns of blue-gray stripes that become permanent inside the tooth, making them difficult to brush away. 

4. White Teeth

Everyone desires to have a bright set of pearly whites, that is no lie. In fact, some people go the extra mile to whiten their teeth as it elicits confidence straight from their smiles. While white teeth may be an indicator of good oral hygiene, there goes a saying that too much of something is bad. 

Note that the formation of white spots or streaks on your teeth may be an implication of excessive fluoride application. Although fluoride is intended to strengthen your teeth, too much amount causes abnormal whitening of teeth.

To prevent this, always seek professionals when undergoing teeth whitening procedures. Just remember that bleaching treatments are safe, given that they are performed by oral care experts. 


Teeth colors play a vital role in helping you see and distinguish the ones that are normal from the ones that aren’t. Make it a requisite to understand their implications as they will give you the key in providing solutions to your dental issues, whenever necessary. As a rule of thumb, always consult with professionals if you feel that your teeth color is causing you worries.
