What is the Actual Color of Healthy Teeth?

Actual Color of Healthy Teeth

First things first. Let’s talk about what the natural color of your teeth actually is. 

The shade of white most natural to your teeth is affected by the two outermost layers that are part of the tooth structure. The hard outer layer, or enamel, is naturally white, so people assume a smile should be white. The inner layer, or dentin, is naturally yellow. If your enamel is too thin, the dentin begins to show through, making your teeth appear yellow. 

So essentially, the natural color of your teeth is determined by how dark your dentin color is and how thin your tooth enamel layer is. 

Understanding the Difference Between Stains

Now, coming to the question, “Why are my teeth yellow when I brush them every day?”

But Why Are My Teeth Yellow When I Brush Them Everyday?

Why Are My Teeth Yellow When I Brush Them Everyday

Let’s get into the nitty-gritty. Your teeth may be stained for a lot of different reasons. Most people think brushing alone is enough to make your teeth appear white and shiny. But that is sadly not the case. 

It is important to remember that brushing isn’t designed to make your teeth white. Brushing your teeth cleans your mouth and prevents tooth decay and oral cavities. But brushing alone cannot whiten your teeth. Some of the foods we consume, medications we take, or our daily habits could contribute to tooth discoloration. 

Let’s look at a few reasons why your teeth are yellow even though you brush them every day. 

Poor Oral Hygiene Habits (No Surprise There)

If you have come to the point where you have to ask yourself, “Why are my teeth yellow when I brush them every day?” then maybe you are doing the actual brushing wrong. 

So, think before you brush and follow the following tips to do it right. 

Brush ‘Em Regularly

Make sure that you brush your teeth at least twice every day without fail. Stopping this practice will make matter much worse than they already are. 

Brush Gently

Brushing your teeth vigorously is not a mark of extra cleanliness. Remember, your teeth are not a piece of furniture that you can attack with a brush and cleanser to polish. 

Brushing your teeth hard will not make them any cleaner. Just take your time and brush your teeth gently. Attacking your teeth with a brush will only erode the outer enamel, exposing the yellow dentin underneath and making your teeth look discolored. 

Rinse With Mouthwash

Add a gentle mouthwash to your daily oral care routine, and use it once a day. The hydrogen peroxide in mouthwash will help your teeth become whiter.  

Brush Your Tongue

Brushing your tongue can eliminate harmful bacteria and plaque, which act as staining agents for your teeth. Make sure to clean your tongue while brushing your teeth gently. 

Foods & Drinks – You Are What You Eat

The diet you consume is largely responsible for any discoloration you might be experiencing on your teeth. Everything you eat leaves a residual sheen in your mouth. Elements such as chromogen, acids, and tannins in your food can stain your teeth over time. 

Some high-staining foods and drinks include: 

Foods & Drinks - You Are What You Eat

Tea & coffee: These are two major culprits for staining your teeth as they are super high in acids and tannins. The surface stains from consuming these two beverages build up over time, making them hard to remove. 

Wine: Red wine has a high number of tannins and can cause tough-to-remove discoloration on your teeth. 

Dark sauces: Dark and heavy sauces such as barbeque sauce, soy sauce, and ketchup can cause extrinsic stains on your teeth. 

Smoking – The Secret Culprit

Smoking - The Secret Culprit

Most people focus on the harmful effect smoking can have on your lungs and body, but no one talks about the toll this habit can take on your teeth and oral cavity. Smoking is one of the primary reasons why your teeth turn yellow over time. The nicotine stains become hard to remove, making your teeth turn a darker shade of yellow slowly. 

If you are a compulsive smoker, brushing your teeth is not enough. You also need to get your teeth professionally cleaned to remove the nicotine stains. 

Medications – Say What?

This might be hard to believe, but heavy medications can cause your teeth to discolor over time and give you dry mouth syndrome

Tetracycline is the most popular drug that causes your teeth to discolor. Other medications for conditions such as cancer or blood pressure can also cause your teeth to turn yellow by drying your mouth. The acidic levels in your mouth increase when your mouth is dry, turning your teeth to an unattractive shade of yellow.
