FAQs: Hydroxyapatite, Oil Pulling, and More

Our Natural Oral Care Products


Will glycerin prevent tooth remineralization?

Glycerin plays a crucial role in the toothpaste formula at Terra & Co. It's highly soluble by saliva even if is left on your teeth. As a committed vegan brand, we prioritize using plant-based glycerin to keep our toothpaste moist and effective, with the added benefit of binding our premium hydroxyapatite powder. Extensive research over the years has shown that toothpaste containing glycerin, hydroxyapatite, or even fluoride will contribute to enamel remineralization. Read studies herehere, and here.

What is the % of Hydroxyapatite in your toothpaste?


At Terra & Co., we take pride in our commitment to transparency. We use a significant 8%-10% concentration of vegan hydroxyapatite in our toothpaste formulation, a key ingredient that promotes enamel health. We believe that consumers deserve complete clarity about the components of their oral care products, and we're dedicated to providing that transparency by showcasing the high-quality ingredients that go into our hydroxyapatite toothpaste for peace of mind and trust in our brand.

Tell us more about the Hydroxyapatite used in your toothpaste and oil?

We'd love too! Terra & Co. uses natural calcium carbonate deposits from mineral origin extracted from quarries in France. Our Hydroxyapatite toothpaste is functionalized to have a calcium carbonate core and Hydroxyapatite shell to improve its efficacy. Our products are both manufactured in the USA and PETA certified vegan and cruelty-free!

Is there vegan Hydroxyapatite?

 Yes! While our competitors use animal-based hydroxyapatite made from egg shells, crab shells, or milk, our hydroxyapatite is vegan! We import it from France, where it's extracted from quarries. This assures that our products only use unique, high-quality natural hydroxyapatite and minerals.

Did you change the formula in your Brilliant Black Toothpaste? 

Yes we did! Why? Because of your invaluable feedback. We wanted to take our paste to the next level by adding biocompatible and non-toxic superhero Hydroxyapatite. This 'fluoride-alternative' mineral aids with sensitivity, tooth remineralization and protects enamel while whitening teeth naturally.

How do I discard my dental floss packaging?

Once enjoyed, our recycled paper dental floss box and it's interior contents are 100% recyclable. Simply remove the metal floss cutter and discard into your designated recycling bins.

Why does some of your packaging have plastic?

It’s true! While we’re aiming for plastic-free perfection, we’re just not quite there yet! The packaging industry as a whole isn’t either and so some of the products do have plastic components like stoppers, liners, and or seals. As a company we continue to learn, research, and study ways where we can improve, and are hopeful to achieve our idea of “eco-perfection” in the not-too-distant future. Follow along and stay tuned as we continue to grow!


How do I recycle my Terra&Co. when finished?


Great question! Most of our natural oral care products are readily recyclable curbside; meaning our recycled FSC certified paper packaging is unlined/non-coated, metal components, and or glass bottles can all be tossed into your designated recycling bins. However, to learn more about the “how” and “where” in your area, we suggest learning more at Earth911 - More Ideas, Less Waste.
