Why do teeth yellow with age? This natural process occurs as enamel thins over time, revealing the underlying, naturally yellow dentin. Factors like food and drinks that stain teeth, lifestyle, and oral hygiene can accelerate this yellow buildup on teeth.

In this article, we'll delve into the causes of tooth discoloration, specifically addressing age-related changes.

We'll also guide you through effective at-home whitening methods, including LED trays, strips, and toothpastes, tailored to combat these age-related changes.

Our goal is to provide you with practical, safe solutions for maintaining a brighter smile as you age, directly addressing your concerns and queries.

What this article covers:

What Causes Tooth Stains?

When it comes to maintaining a bright smile, understanding what causes tooth stains is crucial. At SNOW, we're not just about providing top-notch teeth whitening products; we're also here to educate you on the science behind tooth discoloration.

Tooth stains are primarily caused by two types of substances: chromogens and tannins. Chromogens are intense color pigments that cling to the enamel, the outermost layer of your teeth. Tannins, on the other hand, are plant-based compounds that increase the ability of chromogens to adhere to the enamel.

But that's not all. The acidity in foods and drinks plays a significant role too. Acidic substances can erode the enamel, making it rougher and more susceptible to staining. According to WebMD, acidic foods and drinks make tooth enamel softer and rougher, creating a perfect environment for stains to latch onto.

As dental health experts, we at SNOW understand these dynamics and are committed to providing solutions that not only whiten your teeth but also protect them from future staining.

What Makes Teeth Turn Yellow as You Age?

As we age, our teeth naturally undergo changes that affect their color. The enamel, the hard, protective outer layer of the teeth, gradually wears down. This wear and tear is a natural part of aging and is influenced by the foods we eat, our oral hygiene habits, and general dental care. As the enamel thins, it reveals more of the dentin beneath, which has a yellowish hue. According to WebMD, this process is a key reason why teeth appear more yellow as we age. At SNOW, we've dedicated ourselves to understanding these natural changes and developing products that not only address but also counteract this yellowing effect. Our aim is to provide effective solutions that help maintain the natural beauty of your teeth throughout the aging process.

How Do You Whiten Aging Yellow Teeth?

As we age, our teeth can lose their brightness, but at SNOW, we believe that everyone deserves a confident, radiant smile at any age. That's why we've developed a range of products specifically designed to combat age-related yellowing. Let's explore how each of these products works to restore the natural whiteness of your teeth.

LED Whitening Trays

Our SNOW Teeth Whitening Kit includes LED whitening trays that use state-of-the-art technology to enhance the teeth whitening process. The LED light works in tandem with our whitening agent to accelerate the bleaching effect.

LED lights activate the hydrogen peroxide in teeth whitening products, enhancing their effectiveness. This makes LED whitening trays a powerful solution for tackling age-related yellowing, ensuring your smile stays bright and youthful.

Whitening Toothpaste

Incorporating our Teeth Whitening Toothpaste into your daily routine is a simple yet effective way to combat yellow teeth. This toothpaste contains gentle abrasives and whitening agents that remove surface stains without damaging your enamel.

Regular use can help preserve the natural color of your teeth, making it a staple in your oral hygiene regimen.

Whitening Mouthwash

Finally, our Arctic Frost Teeth Whitening Mouthwash is an excellent addition to your oral care routine. This mouthwash contains ingredients like hydrogen peroxide, which assists in lightening the teeth over time. It's an easy step to add to your daily routine for an extra whitening boost, ensuring your smile remains vibrant and healthy.

At SNOW, we're committed to providing you with effective, easy-to-use products that address the natural yellowing of teeth with age. Our range of whitening solutions is designed to meet your individual needs, helping you maintain a bright and confident smile.

What Are Other Causes of Yellow Teeth?

While aging is a primary factor in the yellowing of teeth, several other elements also play a significant role. Understanding these can help you make informed decisions about your oral care and choose the most effective whitening solutions.


Your diet significantly impacts the color of your teeth. Foods and drinks with strong colorants, such as coffee, tea, and red wine, are known for staining teeth. These substances can penetrate the enamel, leading to persistent discoloration.

At SNOW, we recommend being mindful of these dietary choices and considering our whitening products as a countermeasure.


Tobacco use is another major contributor to yellow teeth. The nicotine and tar in tobacco create stubborn stains that can be difficult to remove.

These stains are not just superficial; they can seep deep into the enamel, making them more challenging to eradicate.

Poor Oral Hygiene

Inadequate brushing and flossing can lead to plaque buildup, which contributes significantly to tooth discoloration.

Regular and effective oral hygiene is crucial in preventing this buildup and maintaining the natural whiteness of your teeth.


Certain medications can also alter tooth color as a side effect. These include some antibiotics, antihistamines, and high blood pressure medications. It's important to discuss these potential side effects with your healthcare provider and consider appropriate dental care measures.

At SNOW, we understand the various factors that contribute to yellow teeth and have developed a range of products to address them. Our whitening solutions are designed to combat the effects of diet, smoking, and poor oral hygiene, helping you maintain a bright and healthy smile.
