Yellow Teeth: Causes and How to Whiten Them

Summary

Yellow teeth can impact confidence and social interactions, but they are not always caused by poor hygiene. Discolouration results from factors like diet, smoking, genetics, ageing, and medical conditions. 

Avoidable causes include staining foods, tobacco use, and poor oral hygiene, while unavoidable factors include genetics and enamel wear. Whitening treatments range from home remedies (baking soda, apple cider vinegar), and over-the-counter products (whitening toothpaste, strips), to professional dental treatments like in-office bleaching and laser whitening. 

Preventing yellowing involves proper oral care, avoiding stain-causing foods, and regular dental checkups. Professional whitening offers the most effective and lasting results for a brighter smile.

Introduction

In a society where physical appearance often influences first impressions, yellow teeth are often associated with bad hygiene. As such, they can significantly affect a person’s social relationships and sense of self.

This perception may lead to feelings of embarrassment and self-consciousness. In fact, the psychological toll can manifest as reduced confidence, isolation—and even anxiety.

However, bad hygiene doesn’t always cause yellow teeth. Yellow teeth can be caused by different factors.

Since smiling is a global expression of friendliness and approachability, this article seeks to dive into yellow teeth. It also aims to discuss teeth-whitening approaches that can help boost social interaction and confidence.

What causes yellow teeth?

Yellow teeth may be caused by a variety of factors. These factors are broadly classified into two categories—avoidable and unavoidable causes.

Avoidable causes of yellow teeth

Avoidable causes of yellow teeth are principally related to one’s lifestyle choices and habits. For example:

• Dietary habits: Foods high in chromogens, like coffee, tea, red wine, and berries, may stain one’s teeth. Furthermore, sugary snacks may contribute to plaque buildup, which may also lead to yellowing
• Smoking and tobacco: Nicotine and tar from smoking and tobacco may also cause yellow teeth.
• Poor oral hygiene: Inadequate brushing and flossing often allow plaque and tartar to accumulate—leading to yellow teeth.
• Certain medications: Some mouthwashes and medications, for instance, chlorhexidine, may stain teeth if used improperly or excessively.

Unavoidable causes of yellow teeth

Examples of unavoidable causes of yellow teeth include:

• Genetics: Some people inherit genes that affect the thickness and colour of their enamel. As such, their teeth are naturally more prone to yellowing.
• Ageing: As people age, the enamel wears away. Consequently, this reveals the yellowish dentin underneath.
• Medical conditions: Conditions like fluorosis may occur due to excessive fluoride exposure during tooth development. This consequently may lead to yellow or brown spots on teeth. Conditions like jaundice or infections may also erode enamel and cause discolouration.
• Trauma: Physical trauma to the teeth can lead to cracks in the enamel, allowing dentin to show through.

Difference between yellow and stained teeth

Although they have different causes and appearances, yellow teeth and stained teeth are related but distinct disorders. Yellow teeth often result from intrinsic factors such as ageing or genetics. As one’s enamel wears down with age, the yellowish dentin beneath may become more visible, giving the teeth a naturally yellow hue.

Genetically, some people are born with thinner enamel or naturally yellower dentin. Furthermore, over time, bad eating and dental practices might make the yellowing process worse. Overall, teeth yellowing is typically uniform across the teeth and may be harder to reverse without professional treatments.

In stark contrast, stained teeth are primarily caused by external factors that affect the surface of the enamel. For example, consuming stain-inducing substances like coffee, tea, red wine, or tobacco. These stains frequently manifest as patches or localised discolourations that change in severity based on the staining agent exposure.

Unlike yellow teeth, these extrinsic stains can frequently be eliminated or lightened with routine dental cleanings, whitening procedures—or better oral hygiene habits.

How to whiten yellow teeth (treatment)?

To whiten yellow teeth, several approaches can be trialled. For instance:

Home remedies for yellow teeth

Home remedies provide affordable and natural ways to whiten yellow teeth. However, their effectiveness varies, and they may not be suitable for everyone. For instance:

• Baking soda: Brushing with baking soda may help to remove surface stains. However, excessive use may erode enamel.
• Apple cider vinegar: Diluted apple cider vinegar can help remove stains due to its acidic properties. However, overuse may damage enamel and increase sensitivity.
• Activated charcoal: Consistently brushing with activated charcoal may help absorb stains and toxins. However, its abrasive nature may harm enamel if used too frequently.

Do note that these remedies may not work for everyone and could pose risks if misused.

Over-the-counter (OTC) yellow teeth solutions

OTC teeth whitening products may provide more dramatic results than home remedies. However, their results depend on the type of discolouration and individual factors. Common examples include:

• Whitening toothpaste: This constitutes mild abrasives or chemical agents like hydrogen peroxide that remove surface stains. However, they may not address deeper discolouration.
• Whitening strips: Coated with peroxide gel, these thin strips can lighten teeth over time with regular use. While effective for extrinsic stains, they might cause temporary sensitivity.
• Whitening mouthwash: Often containing peroxide or other whitening agents, mouthwash can help maintain whiteness when used consistently.

Overall, these products might not be suitable for everyone. As such, it’s imperative to consult a dentist to ensure the right product is chosen for your individual needs.

Dentist treatment for yellow teeth

Professional teeth whitening treatments undoubtedly provide the most effective and reliable solutions for whitening yellow teeth. For instance:

• In-office teeth whitening This dedicated treatment entails applying a concentrated bleaching agent directly to one’s teeth. It’s often combined with special lights or lasers to enhance results—delivering noticeable whitening in one session.

How to prevent yellow teeth and maintain whiteness?

Yellow teeth prevention can be achieved through a combination of dietary adjustments, good oral hygiene practices, and regular dental checkups. For instance:

• Avoid staining foods and drinks: Limit consumption of coffee, tea, red wine, and dark-coloured fruit juices. These foods contain tannins that can stain teeth.
• Brush regularly: Ensure to brush your teeth at least twice a day with whitening toothpaste to eliminate surface stains. Additionally, utilise gentle circular motions and ensure all surfaces are cleaned.
• Utilise a straw: When consuming beverages like soda or juice, consider using a straw to minimise contact with teeth.
• Consume crunchy fruits and vegetables: Foods like apples and carrots can help clean teeth naturally by stimulating saliva production.
• Stay hydrated: Drinking substantial amounts of water to help flush out food particles and bacteria that may lead to plaque and staining.
• Floss daily: Ensure to consistently remove plaque and food particles from between teeth to prevent staining
• Replace toothbrush regularly: Ensure to switch your toothbrush every three to four months or sooner if bristles become frayed.
• Avoid smoking and tobacco: Completely stop smoking and tobacco consumption to significantly improve oral health and reduce yellowing
• Dental checkups: Visit a dentist every six months for professional cleanings to remove tartar and surface stains.

FAQ

Are yellow teeth healthy?

Yellow teeth are not inherently unhealthy. However, their appearance may sometimes indicate underlying oral health issues. In fact, if yellow teeth are accompanied by sensitivity or decay, they may indicate a need for medical attention.

Can yellow teeth get white again?

Yes, depending on what caused the discolouration, yellow teeth can turn white again with the correct treatments. Home remedies like baking soda or whitening toothpaste, as well as over-the-counter solutions like whitening strips, can be helpful interventions.

Why are my teeth still yellow if I brush them every day?

If your teeth remain yellow despite brushing daily, it could be because of several factors beyond basic oral hygiene. For instance, poor brushing techniques may fail to remove plaque effectively or even wear down enamel.

Dietary habits, including frequent consumption of staining foods and drinks like tea, coffee, and red wine, may also cause surface discolouration. Factors like ageing and genetics also play an undeniable role in yellowing teeth, despite one brushing daily.

Can yellow teeth be a sign of an underlying health issue?

Yes, yellow teeth can sometimes indicate an underlying health issue. Specific medical conditions, like celiac disease, diabetes, or liver issues like jaundice, may affect enamel and dentin. Thereby resulting in yellow discoloration.

Additionally, medications like antibiotics (e.g., tetracycline) or treatments like chemotherapy may alter tooth colour. Chronic dry mouth or infections may also contribute by creating an environment for bacterial growth that yellows teeth.

At home vs dental whitening: Which one is better?

The choice between at-home and dental whitening depends on one’s goals, budget, and the severity of discolouration. Professional whitening, performed under a dentist’s supervision, is ideal for significant staining. In fact, it ensures safety by protecting gums and minimising sensitivity. However, it is more expensive and requires an in-office visit.

On the other hand, at-home whitening solutions like strips, trays, or toothpaste are more affordable and convenient. However, they utilise lower concentrations of bleaching agents, leading to slower and less noticeable results. As such, they are better suited for minor stains or maintenance.

What foods should I avoid to prevent yellow teeth?

To prevent yellow teeth, it is imperative to steer clear of foods and drinks that are highly pigmented, acidic, or prone to staining enamel. For instance, beverages like coffee, tea, red wine, and dark-coloured sodas constitute tannins and chromogens, which may cause discolouration.

Acidic foods such as citrus fruits, tomato-based sauces, balsamic vinegar, and fruit juices can also erode enamel. Thus, making teeth more porous and susceptible to stains. Deeply pigmented foods like berries, cherries, beets, and curry may also leave behind strong stains on teeth. Additionally, sticky foods like balsamic vinegar or sugary snacks may contribute to plaque buildup, which exacerbates yellowing.

What is the cost of dental whitening treatment to treat my yellow teeth?

The cost of tooth whitening in Malaysia varies greatly based on the type of treatment, the clinic, and the degree of yellowing. It’s imperative to consult an experienced dental practitioner for a customised evaluation and precise cost estimate based on your unique requirements.

Conclusion: Embracing a brighter, healthier smile
