Welcome to our guide exploring the question: why are teeth white? Here, we delve into the reasons behind the natural whiteness of teeth. Teeth are naturally white due to the enamel, a hard substance that reflects light.

This article will cover the science of teeth color, evaluate the safety and effectiveness of whitening products, and guide you in choosing the right shade for your smile. 

Additionally, we'll discuss the causes of tooth discoloration and answer common questions about teeth whitening.

Designed for young professionals, beauty enthusiasts, and anyone seeking a brighter smile, this guide offers valuable insights and practical tips for achieving a healthy, radiant smile.

What this article covers:

Are Teeth Supposed to Be White?

When it comes to the color of teeth, there's often a misconception that they should be a brilliant white. However, the natural color of teeth is not purely white. Let's delve into what determines the color of your teeth and who can benefit from teeth whitening.

What Makes Teeth White?

Teeth are naturally white due to the enamel, the hard, outer layer of your teeth. This enamel is composed of crystalline structures that reflect light, giving teeth their white appearance. However, it's important to note that the degree of whiteness varies among individuals. The thickness and smoothness of enamel can affect how light is reflected and, consequently, the brightness of your teeth. Our SNOW whitening products are designed to enhance this natural whiteness, catering to the unique characteristics of each individual's teeth.

What Color Is A Healthy Smile?

A healthy smile is often perceived as having bright, white teeth, but in reality, the natural color of teeth can vary significantly. According to WebMD, the natural color of teeth can change and doesn't always appear as bright or white as one might expect. Teeth may darken, turn from white to different colors, or develop white or dark spots in places.

Who May Benefit From Teeth Whitening?

Our SNOW products cater to a wide audience, including young professionals, beauty enthusiasts, and individuals with teeth discoloration. Teeth whitening can be particularly beneficial for those looking to enhance their appearance for special occasions, such as weddings or job interviews, or for anyone who wants to boost their confidence with a brighter smile.

It's also a great solution for those experiencing discoloration due to factors like aging, lifestyle habits (such as smoking or consuming stain-causing foods and drinks), or certain medications. With our inclusive approach, we ensure that our products are suitable for a diverse range of individuals, including those with sensitive teeth.

In summary, while teeth are naturally white due to enamel, the shade can vary, and a healthy smile isn't defined by the whiteness of teeth alone. At SNOW, we're committed to providing safe and effective whitening solutions to help you achieve and maintain a smile that you're proud of.

How Do You Choose the Right ‘White' for You?

Choosing the right shade of white for your teeth is more than just picking the brightest option available. It's about finding a balance that complements your overall appearance and meets your personal aesthetic goals. At SNOW, we understand the importance of this decision and are here to guide you through the process.

Consider Your Skin Tone

Your skin tone plays a significant role in determining the right shade of white for your teeth. According to American Dental Clinic, fairer skin tones may benefit from slightly softer shades of white, as too bright a shade can create an unnatural contrast. Conversely, darker skin tones can often carry off brighter whites, enhancing the overall brilliance of your smile.

Assess The Health Of Your Teeth

The health of your teeth is another crucial factor. If your teeth have restorations like fillings or crowns, it's important to match the whitening level to these existing dental works for a uniform look. Our experts at SNOW can help assess your dental health and suggest the most suitable whitening approach.

Understand Realistic Whitening Ability

It's essential to have realistic expectations about teeth whitening. Not everyone's teeth can achieve the same level of whiteness, often due to genetic factors or the natural color of your teeth. We at SNOW offer a range of products that cater to different whitening needs, ensuring you get the best possible results.

Align With Your Overall Style

Your personal style and the image you want to project should also influence your choice. If you prefer a more natural look, a subtler shade of white might be more appropriate. For those who want a more striking change, a brighter shade could be the way to go.

In summary, choosing the right shade of white for your teeth involves considering your skin tone, the health of your teeth, realistic whitening expectations, and your personal style. At SNOW, we offer a variety of shades and our experts are here to guide you in selecting the perfect one for a natural and attractive look.

What Are the Causes of Tooth Discoloration?

Tooth discoloration is a common concern for many, and understanding its causes is crucial in choosing the right whitening approach. At SNOW, we recognize the importance of this knowledge in helping our customers achieve their desired smile.

Extrinsic Causes

Extrinsic tooth discoloration affects the surface of the tooth. According to Healthline, common causes of extrinsic stains include foods, beverages, and tobacco. Foods like red sauces, chocolate, and certain fruits, along with beverages such as red wine, tea, and coffee, are known culprits.

Tobacco use, whether it's smoking cigarettes or chewing tobacco, can also cause significant tooth discoloration.

Intrinsic Causes

Intrinsic stains are located within the tooth and are often more resistant to over-the-counter whitening products. These can be due to certain medications, trauma or injury to a tooth, tooth decay, excessive fluoride, or genetics.

For instance, antibiotics like tetracycline, when taken during childhood, can lead to permanent tooth discoloration.

Age-Related Discoloration

As we age, the enamel on our teeth begins to wear away, often resulting in a yellow appearance. Age-related discoloration may be caused by both extrinsic and intrinsic factors.

The thinning enamel exposes the dentin, which is naturally yellower than enamel, leading to an overall change in tooth color.

Prevention And Treatment

Preventing tooth discoloration involves good oral hygiene practices and being mindful of the consumption of stain-causing foods and beverages. Regular dental cleanings and checkups are also crucial in maintaining the natural color of your teeth.

For those looking to treat existing discoloration, SNOW offers a range of whitening products that cater to different needs, from our advanced whitening kits to daily whitening toothpaste.

White Teeth FAQs

Why should I whiten my teeth?

Whitening your teeth can enhance your appearance, boost self-confidence, and make a positive impression in social and professional settings.

Why are my teeth turning yellow?

Teeth turn yellow due to a variety of reasons, such as aging, diet, poor dental hygiene, and the thinning of enamel which reveals the underlying dentin.

Why do some people have naturally white teeth?

Genetics play a significant role in natural tooth color. Some people are born with thicker and whiter enamel, giving them naturally brighter teeth.

Can tooth trauma make them appear darker or yellower?

Yes, tooth trauma can lead to discoloration as the injury may cause internal bleeding or damage to the nerves, affecting the tooth's color.


From the natural coloration of teeth influenced by genetics and lifestyle to the safe use of teeth whitening products, each aspect plays a crucial role in achieving that perfect smile.
