No, Charcoal Toothpaste Won’t Whiten Your Teeth (And It Could Do More Harm Than Good)

By Dr. Justin Raanan
Dental Care of Brentwood

Thinking about hopping on the charcoal toothpaste trend for a brighter smile and whiter teeth? You might want to think twice. At Dental Care of Brentwood, we’re committed to helping the residents of Brentwood achieve truly healthy, whiter teeth. Despite the significant buzz and celebrity endorsements, a growing body of evidence, including reviews in the British Dental Journal, suggests that charcoal-based toothpastes are largely a “marketing gimmick” with no proven whitening benefits for your teeth. Indeed, it is crucial to understand that charcoal toothpaste won’t whiten your teetheffectively or in any lasting way. Furthermore, it could potentially increase your risk of tooth decay and staining on your beautiful teeth.

The Truth Behind Charcoal Toothpaste and Its Whitening Claims

Understanding the Allure of Black Paste

Many charcoal toothpastes make bold claims of being “anti-bacterial,” “anti-fungal,” and offering “tooth whitening” or “reducing tooth decay.” However, as Dr. Joseph Greenwall-Cohen, co-author of a study from the University of Manchester Dental School, points out, reviews of dozens of charcoal toothpaste products found claims made by these products to be unproven. Consequently, there is simply no scientific evidence to back up these assertions that charcoal can whiten teeth.

The “Perceptual Improvement” of Whiter Teeth

The perceived whitening effect on your teeth after using charcoal toothpaste might simply be a “perceptual improvement.” To illustrate, coating your teeth in a black charcoal paste and then rinsing it away can create the illusion of whiter teeth, even if no real change has occurred to your tooth enamel. This superficial trick, therefore, doesn’t truly whiten your teeth. Remember, charcoal toothpaste won’t whiten your teeth beyond this temporary visual effect. Furthermore, this lack of genuine whitening can lead to disappointment.

Significant Risks Outweigh Non-Existent Whiten Teeth Benefits

Beyond the lack of proven effectiveness to whiten teeth, Dental professionals at our Brentwood office express significant concerns about the potential risks associated with using activated charcoal on your teeth. These risks, ultimately, make it clear why charcoal toothpaste won’t whiten your teeth safely.

Lack of Fluoride Protection for Your Teeth

A major concern for your teeth is that many charcoal products contain no fluoride, which is essential for protecting your teeth against decay. Without this vital ingredient, your teeth remain vulnerable. A healthy tooth, furthermore, needs fluoride to protect its surface from daily wear and tear. Therefore, relying solely on charcoal toothpaste can be detrimental.

Abrasiveness and Enamel Damage: A Double Threat

Charcoal particles, derived from materials like nutshells, coconut husks, bamboo, or even wood and coal, are abrasive. Consequently, excessive brushing with these charcoal products can wear down your precious tooth enamel. This leads to more sensitive teeth and, as a result, potentially increases the risk of further staining on your teeth. This occurs as the yellower dentin underneath becomes more exposed. Ultimately, this damage makes it harder to truly whiten your teeth in the future. Moreover, once enamel is lost, you cannot regain it.

Gum Irritation and Oral Health

Furthermore, fine charcoal particles can also get caught in the gums surrounding your teeth, leading to irritation and discomfort. Healthy gums, after all, are crucial for healthy teeth. Moreover, such irritation can sometimes lead to more serious periodontal issues if you leave it unaddressed. Thus, maintaining gum health is paramount.

Compromising Fillings and Restorations

If you have fillings or other Dental restorations, charcoal particles can get into them and become difficult to remove. This potentially compromises the filling itself or stains your restored tooth. Therefore, exercise caution, especially if previous dental work could affect your teeth. In summary, the risks extend beyond natural tooth surfaces.

As Prof Damien Walmsley from the British Dental Association states, “Charcoal-based toothpastes offer no silver bullets for anyone seeking to whiten their teeth and come with real risks attached to their teeth. So don’t believe the hype. Instead, trust your dentist at Dental Care of Brentwood for advice on whitening your teeth.”

Potential Risks of Using Charcoal Toothpaste on Your Teeth

A summary of the dangers associated with using charcoal toothpaste on your teeth:

Risk CategorySpecific IssueExplanation
Enamel & DentinAbrasive ErosionCharcoal’s abrasive nature can wear down precious tooth enamel, leading to sensitivity and exposure of the yellower dentin beneath your teeth.
Gum HealthIrritation & InflammationFine charcoal particles can lodge in the gum line, causing irritation, inflammation, or even gum recession around your teeth over time.
Tooth DecayLack of Fluoride ProtectionMany charcoal toothpastes lack fluoride, the key ingredient for strengthening enamel and preventing cavities in your teeth.
RestorationsDamage to Fillings & CrownsCharcoal particles can get trapped in the microscopic crevices of fillings, veneers, and crowns, potentially discoloring or damaging these restored teeth.
StainingParadoxical StainingWhile claiming to whiten your teeth, the rough surface created by abrasion can make your teeth more prone to staining from food and drink, making them appear less whitened.

FAQs About Whitening Your Teeth

At Dental Care of Brentwood, your dentist is always ready to answer your questions about keeping your teeth healthy and whitening your smile. Here are answers to common questions about charcoal toothpaste and whitening your teeth:

Does charcoal toothpaste actually whiten teeth?

No, there is no scientific evidence or clinical research to prove that charcoal toothpaste won’t whiten your teeth effectively. Any perceived improvement in your teeth’s brightness is likely a temporary optical illusion or a placebo effect. It simply doesn’t whiten teeth in a meaningful way.

Is charcoal toothpaste safe for long-term use on your teeth?

Dental professionals and your dentist express concerns about its long-term safety for your teeth. Due to its abrasive nature and often lack of fluoride, it’s not recommended for regular or prolonged use if you wish to protect your teeth.

What are the main risks associated with using charcoal toothpaste on your teeth?

The primary risks for your teeth include enamel erosion, increased tooth sensitivity, gum irritation, potential for tooth decay (due to lack of fluoride), and damage or discoloration to existing Dental fillings or restorations on your teeth. Your dentist would advise against these risks for your teeth.

Why is the lack of fluoride in charcoal toothpastes a concern for my teeth?

Fluoride is a crucial mineral that strengthens tooth enamel and helps prevent cavities in your teeth. Without it, your teeth are more vulnerable to acid attacks and decay. Your dentist in Brentwood always emphasizes fluoride for strong teeth.

Can charcoal toothpaste damage tooth enamel, making it harder to whiten teeth later?

Yes, activated charcoal is abrasive. Regular brushing with it can wear down your precious tooth enamel, which does not regenerate. This can lead to increased sensitivity in your teeth and a duller, more yellow appearance as the underlying dentin becomes more visible, making it even harder to truly whiten your teeth later. Consequently, consult your dentist before trying anything that could harm your teeth.

How does charcoal toothpaste affect dental fillings in my teeth?

Charcoal particles can become lodged in the tiny crevices of Dental fillings (like composite resins) and crowns on your teeth, making them appear discolored or potentially compromising their integrity. Your dentist, ultimately, wants your teeth and their restorations to last.

If charcoal doesn’t whiten, why do people think it does?

The perceived whitening of teeth is often a “perceptual improvement.” The stark contrast of black paste on teeth followed by rinsing can create the illusion of a brighter smile, even without actual changes to the tooth shade. It’s a visual trick, not true whitening of your teeth.

What do dental associations (like the ADA/BDA) say about charcoal toothpaste and whitening teeth?

Major Dental associations, such as the American Dental Association (ADA) and the British Dental Association (BDA), do not endorse or recommend charcoal toothpastes due to the lack of scientific evidence supporting their claims, especially for whitening teeth, and significant concerns about potential harm to your teeth. Your dentist, therefore, will echo these concerns.

What are some effective and safe ways to whiten my teeth, as recommended by a dentist?

Effective and safe options to whiten your teeth include professional in-office whitening treatments provided by your dentist, custom-fitted take-home whitening trays from your dentist, and certain ADA-approved over-the-counter whitening products, used as directed. Always consult your dentist at our Brentwood Dental office first for the best way to whiten your teeth. We specialize in dentistry that gets results.

Should I continue using charcoal toothpaste if I already have it, or should my dentist advise differently?

It’s strongly recommended to discontinue using charcoal toothpaste for your daily oral hygiene routine. Switch to a fluoride-based toothpaste for effective cleaning and cavity protection for your teeth. Discuss any whitening goals for your teeth with your dentist at Dental Care of Brentwood. Our dentistry experts are here to help you achieve a truly bright and healthy smile.
