Beyond the Percentage: Why We're Updating Our Nano-Hydroxyapatite Toothpaste

Why We Updated Our Nano-Hydroxyapatite Toothpaste to 7%
Thoughtful ingredients. Trusted quality. Fair pricing. More choices ahead.
At Smart Charlie Naturals, we believe that creating a great toothpaste isn't about following trends or simply adding more of an ingredient. It's about understanding the ingredients we use, carefully evaluating their quality, and continually looking for opportunities to improve.
With more than 25 years of manufacturing experience guiding our approach, continuous improvement has always been central to our philosophy.
Today, we're sharing an important update to our toothpaste across all flavors, why we've made this decision, and what it means for the future of Smart Charlie Naturals.
Why We're Moving From 10% to 7% Nano-Hydroxyapatite
As part of our ongoing product development, we've refined our toothpaste formulation across all flavors from 10% to 7% nano-hydroxyapatite (n-HA).
Nano-hydroxyapatite is a mineral-based ingredient studied for its ability to support enamel remineralization and help reduce tooth sensitivity.
For years, much of the conversation surrounding nano-hydroxyapatite toothpaste has focused on concentration. It's understandable to assume that a toothpaste containing 10% must be more effective than one containing 7%.
But the science is more nuanced.
Research has explored the benefits of hydroxyapatite toothpaste at different concentrations, including formulations below 10%. Importantly, concentration alone does not determine the effectiveness of a finished toothpaste.
Ingredient characteristics, formulation balance, and the way ingredients interact can all influence performance.
In an insightful interview published by Fluidinova, dentist and oral health educator Dr. Mark Burhenne discusses why higher percentages don't automatically translate into better results.
His perspective reinforces a principle we believe strongly at Smart Charlie Naturals:
More isn't always better. What matters is using thoughtfully selected ingredients in a carefully developed formulation.
Our transition to 7% reflects that philosophy. While we haven't conducted comparative clinical testing between our previous and updated formulas, available research supports considering more than concentration alone when evaluating nano-hydroxyapatite toothpaste.
Not All Nano-Hydroxyapatite Is Created Equal
One of the most important—and often overlooked—considerations in nano-hydroxyapatite toothpaste is the quality of the ingredient itself.
Two toothpastes may advertise the same percentage of nano-hydroxyapatite, yet the materials used can differ significantly.
Important considerations include:
-
Purity: The quality and composition of the raw material.
-
Particle characteristics: Size, shape, and other physical properties that can influence how the ingredient behaves.
-
Manufacturing consistency: Reliable production standards and ingredient specifications.
-
Safety evaluation: Scientific assessment of materials under defined conditions of use.
-
Formulation compatibility: How the ingredient works within the complete toothpaste.
European scientific authorities have evaluated specific forms of nano-hydroxyapatite for use in oral care products, with detailed attention to particle characteristics and safety.
Fluidinova, a manufacturer specializing in nano-hydroxyapatite, has publicly highlighted its material-specific European safety evaluation and the importance of rigorous ingredient standards.
These distinctions matter because a percentage on a label tells you how much of an ingredient is present—not everything about its quality.
At Smart Charlie Naturals, we believe responsible ingredient selection deserves just as much attention as concentration.
Our approach is guided by thoughtful sourcing considerations, ingredient quality, and continuous refinement of the finished product.
We don't believe quality should be measured by percentage alone.
Why Our Price Remains Unchanged
We believe transparency and fair pricing should go hand in hand.
As a small business, we've experienced increasing costs for ingredients, production, packaging, and shipping. Rather than automatically passing these increases along to our customers, we've made a conscious effort to absorb them whenever possible.
Interestingly, while our updated formula contains a lower concentration of nano-hydroxyapatite, our overall cost to produce the finished toothpaste has actually increased.
We understand that customers may reasonably question why the price remains unchanged when the concentration of a featured ingredient has been reduced.
It's a fair question—and one we believe deserves an honest answer.
Our pricing reflects the complete product, not simply the amount of one ingredient. It considers ingredient quality, the overall formulation, manufacturing, packaging, and the care that goes into every jar.
We also recognize that value must be meaningful to our customers.
That's why we've maintained our regular retail price of $20 per jar, while continuing to provide:
-
10% off purchases of two or more jars.
-
Free shipping on qualifying three-jar orders.
-
Consistent everyday pricing, despite increasing production and shipping expenses.
For customers purchasing three jars, that means $54 delivered, reflecting both the multi-jar discount and complimentary shipping.
Our goal isn't simply to maintain a price. It's to maintain a fair relationship with our customers—one where quality, transparency, and value remain priorities.
Looking Ahead: More Toothpaste Choices for Different Needs
Our transition to 7% nano-hydroxyapatite is also part of something bigger.
We're developing a broader toothpaste collection designed to provide customers with more options for their individual oral care preferences.
Our vision includes three distinct offerings:
Everyday Toothpaste
A future option focused on simple, purposeful ingredients and an approachable everyday oral care experience.
Our Current 7% Nano-Hydroxyapatite Toothpaste
Our refined toothpaste across all flavors, featuring 7% nano-hydroxyapatite and our continued emphasis on thoughtful formulation, ingredient quality, and value.
Professional Toothpaste
A future specialized formulation designed to expand the choices available to customers seeking a different oral care experience.
Each option will be developed with the same underlying philosophy: quality ingredients, purposeful formulation, and honest communication.
These future offerings are still in development, and we'll share additional details as their formulations and availability are finalized.
Our goal is not to suggest that everyone needs the same toothpaste—or that the highest concentration is automatically the best choice.
It's to provide thoughtful options so customers can select products that align with their individual preferences and oral care routines.
Continuous Improvement Is a Commitment, Not a Destination
At Smart Charlie Naturals, we don't believe product development should stop once a formula reaches the shelf.
We believe in continuing to learn, evaluate, refine, and improve.
Sometimes that means reconsidering an ingredient. Sometimes it means adjusting a concentration. And sometimes it means developing entirely new options to better serve our customers.
What doesn't change is our commitment to approaching those decisions thoughtfully.
We also believe customers deserve to know when a product they trust has changed. That's why we're openly communicating our transition from 10% to 7% nano-hydroxyapatite.
We want you to understand not only what's changing, but the principles guiding our decisions.
Our Promise to You
As Smart Charlie Naturals continues to evolve, our commitment remains rooted in five principles:
Quality ingredients. Thoughtful formulation. Continuous improvement. Transparent communication. Fair pricing.
We're excited about the next chapter of Smart Charlie Naturals and the opportunity to bring you more choices in natural oral care.
Thank you for supporting our small business and trusting us to be part of your daily routine.
Our formulation may evolve, but our commitment to earning your trust never changes.
