What Are The Causes Of Yellow Teeth?

The best way to stop tooth discoloration is taking proactive steps. Read here to learn the causes of yellow teeth so you can keep your pearly white bright.

Have you noticed your teeth are looking a little more yellow than they used to?

There are actually a lot of things you can do to keep your teeth nice and white, and it starts with taking proper care of your teeth.

So let’s look at some of the causes of yellow teeth and how you can avoid it.

Why Do Teeth Turn Yellow?

The outside layer of your teeth is called enamel, and it’s what gives your teeth their white appearance.

The next layer of your teeth is called dentin, and it is a yellowish-brownish color.

When your enamel starts to get thin, it becomes translucent. This causes the dentin to be seen through the teeth, which is what makes your teeth look yellow.

What Causes Yellow Teeth?

Any number of things can weaken your enamel and cause your teeth to turn yellow, including eating certain types of food or drink.

Take a look at these main causes of teeth discoloration.

Poor Dental Hygiene

If you don’t clean your teeth properly, they won’t stay healthy. That means your enamel will start to thin and make your teeth look yellow.

The best way to avoid getting yellow teeth is prevention, and cleaning your teeth plays a huge part in that.


Either smoking this or chewing it can cause your teeth to stain.

Foods and Drinks

Some foods and drinks can actually soften your enamel when you eat them, which makes it easier for them to stain your teeth.

These include things like:

  • tea
  • coffee
  • soda
  • Sugary candies
  • Wine
  • Fruit juices
  • Some fruits (like pomegranates, blueberries, and apples)

You might think brushing your teeth right after eating these foods will keep your teeth from staining, but because your enamel is softer after eating these foods, you should wait at least 30 minutes to brush.

Instead, drink water immediately after you eat any of these foods. This will help clean the teeth and keep them from staining.


As you get older, your enamel weakens and thins. It’s just a natural part of aging.


Some people have naturally thinner enamels that make their teeth look more yellow than others. This doesn’t mean their teeth are unhealthy, it’s just how their teeth grow.

Illness and Medication

Some illnesses can affect the thickness of the enamel. Even some medications, like tetracycline and doxycycline, can make teeth look more yellow as well.

What Can I Do About It?

The best thing you can do that will keep your teeth from turning yellow is take proper care of them. This means brushing your teeth correctly, flossing, and using an antiseptic mouthwash.

When you clean your teeth like this, your enamel will stay strong, thick, and plaque free.

But if you already have yellow teeth, you can also get some teeth whitening treatments.

Keep Your Teeth Healthy

Sometimes, keeping your teeth from turning yellow involves a lifestyle change. Avoiding eating foods you know will stain and quitting tobacco are some good places to start. Add that with proper dental care, and your teeth should stay white.

These lifestyle changes may not get rid of stains that are already on your teeth. If you want to turn your smile around, you should check out our teeth whitening services.
