Years of carrying out a flawless teeth cleaning routine by religiously brushing them 3 times a day and your teeth still have that yellowish color? Annoying, isn’t it?.

You may think you’re doing something wrong, but the answer is… No! Healthy teeth can also be yellow.

Can healthy teeth be yellow?

There are several factors or agents that influence the society in which we live, such as advertising, public figures; they influence that we want a totally white tooth, but you must know that nobody has white teeth by nature.

However, our habits aren’t the only thing that affects our teeth color.

Why are my teeth not white, but yellowish?

Genetics determine the color of our teeth, as well as age.  

As we age, the shade of our teeth often becomes more yellowish, as the enamel begins to wear away, exposing the dentin.

Dentin is the inner part of the tooth (ivory), which is… Guess? Yellow! And it’s covered by enamel, which is translucent.

Depending on the thickness of the enamel, the dentin can be exposed more or less, and create the yellowish color on our teeth. 

Slightly yellow teeth can be healthier, because of the dentin reflecting off the enamel. 

Yellow teeth may be healthier, but that does not mean that they are not exposed to staining or discoloration by external agents. 

What are stains on teeth?

Discoloration of teeth can occur as a result of stains in the enamel, due to actual changes in the material of the teeth, or due to a combination of several factors.

Intrinsic Stains: These types of stains are the most common, as they are created by factors that we cannot control, and are located below the surface of the tooth.

Mostly, taking strong medication during the process of forming our teeth creates those stains. As well as decalcification, knocks, and dental aging. 

Extrinsic stains: Unlike intrinsic stains, you can find them on the surface of the tooth, and are a product of the deterioration on the protein film that surrounds the enamel. 

Extrinsic stains are product of “bad habits”, and the best way to control them is to stop exposing our teeth to products that contain chromogens (food, drinks, tobacco) 

A study by Mark Wolff, a professor and chairman of the department of cariology and comprehensive care at NYU’s College of Dentistry, in which they soaked cows’ teeth for an hour in black tea, red wine and white wine — the same effect as drinking a couple of glasses of wine over a quiet dinner.

The red wine left the strongest stains, while the tea left no stains unless the white wine preceded it. 

“When combined with the beverage’s acidity, the tannins in white wine act as a binding protein and help chromogens to saturate the tooth’s surface,” Wolff said. So when you linger over a cup of tea at the end of dinner, you are inadvertently discoloring your teeth.
