A $16 charcoal toothpaste that publishes its abrasion data
Terra & Co.'s flagship is a 3.4 oz (100.5 ml) recyclable tube of fluoride-free whitening toothpaste built on micro-hydroxyapatite, the calcium phosphate mineral the brand positions as its fluoride alternative, with activated charcoal for stain lifting. Xylitol, baking soda, and peppermint essential oil round out the formula, and the tube lists it as vegan, made in the USA, and free of SLS, triclosan, parabens, and artificial flavors or colors.
The brand publishes its lab numbers on a dedicated clinicals page: a reported RDA abrasion value of 103.37 plus or minus 2.47, an REA of 4.64 plus or minus 0.17, and a third-party shade study in which 16 specimens measured an average 2.7 shades lighter on the R-20 shade guide after 1 to 3 weeks of in vitro treatment. Those are Terra & Co.'s own figures, and the whitening result comes from a lab pellicle test on specimens rather than a live brushing trial, so read them as brand-reported evidence of surface stain removal, not independent proof.
The single tube is $16.00. A Subscribe and Save plan cuts that to $12.80 per tube at 20% off, with delivery every month, 2 months, or 3 months and cancel-anytime terms per the brand. The same product page sells two bundle variants: the black tube paired with the Gentle Green sensitive toothpaste for $30.00, or paired with the Brilliant Black oil pulling rinse for $51.20. The flagship page shows a 4.7 average across 20 reviews, a small base worth noting.
Where it gives ground: there is no fluoride version for buyers who want one, the whitening evidence is in vitro rather than clinical, and the return policy is narrow. Terra & Co. refunds or replaces only items that arrive damaged or defective, and you must report them within 14 days of delivery with an order number and a photo. There is no change-of-mind return window once a tube ships.

Terra & Co. Brilliant Black Whitening Toothpaste - buyer FAQ
Does Terra & Co. Brilliant Black toothpaste contain fluoride?
No. It is a fluoride-free formula that uses micro-hydroxyapatite, a calcium phosphate mineral, as its enamel-support ingredient, alongside activated charcoal, xylitol, baking soda, and peppermint oil. The brand markets hydroxyapatite as its fluoride alternative for remineralization and sensitivity. Each recyclable tube is 3.4 oz (100.5 ml) and sells for $16.00 on terraandco.com.
Is Brilliant Black charcoal toothpaste safe for tooth enamel?
Terra & Co. reports in-house and third-party abrasion testing with an RDA value of 103.37 plus or minus 2.47 and an REA of 4.64 plus or minus 0.17, and markets the paste as low abrasion and safe for twice-daily brushing. Those are brand-published figures; buyers who want independent verification should ask their dentist.
How much does Terra & Co. Brilliant Black toothpaste cost?
A single 3.4 oz (100.5 ml) tube costs $16.00 on terraandco.com. Subscribing drops it 20% to $12.80 per tube, with delivery every 1, 2, or 3 months and cancel-anytime terms. The same product page offers a two-paste bundle with Gentle Green for $30.00 and a toothpaste plus oil pulling bundle for $51.20.
Does Brilliant Black toothpaste actually whiten teeth?
Terra & Co. cites a third-party in vitro study in which 16 specimens measured an average 2.7 shades lighter on the R-20 shade guide after 1 to 3 weeks of treatment. That is in vitro lab pellicle testing on human specimens, not a live brushing trial, so treat the whitening figure as a brand-reported result for surface stain removal.
What is Terra & Co.'s return policy?
Narrow. Refunds or free replacements apply only to items that arrive damaged or defective, and you must email hello@terraandco.com within 14 days of delivery with your order number, a photo, and a short description of the issue. There is no general satisfaction window, so a $16.00 tube you simply dislike is not returnable.
