A NATURAL TEETH WHITENER THAT DOES MORE.
Grind goes beyond surface clean. It helps lift stains, polish, and naturally support enamel rebuild—so your smile’s not just brighter, it’s tougher.
DENTIST OWNED 
NOTE: Recommended by Dr. Jay Grossman, D.D.S., Chief Dental Advisor, Grind Oral Care. 2021: “Grind has a RDA score of 79, out of an upper limit of 250, making Grind one of the least abrasive toothpastes on the market.” -Dr. Jay Grossman, 2021.
MODERN SCIENCE 
Instead of old-school fluoride, Grind features hydroxyapatite (a gold standard oral heath ingredient in Japan), and theobromine (a modern marvel in dentistry). Backed by science, both have the capacity to help remineralize enamel; therefore, we combined both as our natural alternative to fluoride.
THE EXTRAS 
Grind is vegan, cruelty free, and fluoride free with no weak sauce… meaning no SLS, SLES, DEA, BPA, gluten, dyes, peroxide, triclosan, parabens, artificial flavors, artificial sweeteners or harsh whiteners.
THE FEATURES
Hydroxyapatite + Theobromine Remineralization. Strengthens enamel & helps fight sensitivity Baking Soda + Charcoal Gently whitens teeth Coconut Oil Reduces harmful bacteria and promotes oral hygiene Aloe Vera Soothes and moisturizes gums and oral tissues Ginseng Helps protect gums and promotes tartar control Tea Tree Oil Fights bacteria and helps the gums Black & Green Tea Helps protect the gums and reduces inflammation Xylitol Reduces cavity-causing bacteria and promotes oral health
GRIND… IT WORKS 
Finally, a toothpaste that works as hard as you do.
What is the Relative Dentin Abrasion (RDA) score?
Grind has an RDA score of 79.
Will Grind actually whiten my teeth?
Yes! Charcoal is just one of four whitening ingredients we’ve combined to create this NATURAL whitener. Keep in mind, everyone is different and personal habits can impact results.
How does Grind taste?
Amazing! Like no other charcoal paste. If you’re looking for a gritty paste that tastes like chalk or better yet, Earth, you’ll want to look elsewhere. We spent a lot of time on taste. Resulting in a special vanilla-coconut-mint flavor.
Does Grind foam?
Yes! We use two foaming ingredients (derived from coconut oil) to distribute the paste & remove debris. No SLS, SLES, DEA or sulfates!
Why should I give Grind a try?
Because fate brought you here…. and because we’re different. Instead of choosing fluoride or stoping at “fluoride-free”, we paired TWO fluoride alternatives. A next-gen toothpaste with a mission on the backend.

NATURAL, CLEAN & BIOCOMPATIBLE. No fluoride. No sulfates. No parabens. No fake flavors. Just a biocompatible, vegan-friendly toothpaste stacked with clean ingredients your mouth actually wants. Designed for daily use. Safe for your grind—and your family’s.
FOR SENSITIVE TEETH—NOT SENSITIVE PEOPLE. If brushing hurts, your old toothpaste failed you. Ours doesn’t. Grind’s sulfate-free formula goes easy on nerves, hard on plaque. Comfort without compromise.
FLAVOR WITH TEETH. Mint and vanilla hit first. Then coconut oil goes to work. This isn’t bland. It’s bold. A flavor rebellion that makes brushing the best part of your day—and your breath? Unstoppable.

Finally, effective protection without fluoride!
Grind is the first hydroxyapatite toothpaste I’ve ever tried, and I don’t think I’ll go back! It leaves my teeth feeling clean and glossy without irritating my gums or mouth at all. Lots of brand-name toothpastes dry out my mouth or cause a mild skin reaction, but this one cleans gently and effectively. No sulfates, parabens, peroxide or other harsh chemicals – it’s got lots of nourishing natural ingredients instead. The mint flavor is nice and refreshing but not overly harsh.What sealed the deal for me was reading research on the effects of hydroxyapatite compared to fluoride. Both are equally effective at protecting teeth from cavities and decay, but hydroxyapatite (unlike fluoride) is biomimetic – meaning it is the same compound the body uses to repair enamel naturally. There’s a decent amount of research to back up its use in dental health, and I’m really not sure why it’s not more popular in American toothpastes! Many natural / fluoride-free toothpastes don’t choose ingredients that prevent cavities in the same way, and the handful that do are expensive and hard to find.If you’re used to heavy-duty whitening toothpaste, the activated charcoal in this formula won’t give you the same “glowing” effect, but I find it very effective over time to remove stains on teeth. It’s also a little pricier than most drugstore brands, but I’m happy to pay the premium for a product with an ingredient list I can understand and trust… ESPECIALLY for a product I’m putting in my mouth twice a day. I hope it’s back in stock soon, I really don’t want to switch back to anything else!

Made in America and small business 💚

Leaves a lot of residue!
The toothpaste is great, BUT the residue is crazy! Me and my wife found ourselves cleaning black residue every day because its very visible, Im sure its the same with white toothpaste but it’s definitely more noticeable with Black Toothpaste! You’ve been warned!

The only toothpaste I bother with
Grind is my favorite toothpaste. If you’re stuck in the Colgate/Crest loop, this toothpaste will change your mind about what toothpaste could and should be. The toothpaste literally sparkles and has whitened my teeth substantially, and without peroxide or other chemicals. It tastes great and is less overwhelmingly minty than common commercial brands. I started getting positive feedback from my hygienist almost immediately when I started to using Grind and have been using it for years now. I cannot recommend it enough.

Grind in a Good way
I was a little hesitant at first about using charcoal on my teeth, but after reading about the story of Grind Oral Care and asking my dentist I decided to give it try.I didn’t hurt either that Roger who founded Grind Oral Care served in the military was working to start his own business making oral care products.I have been using Grind for 8 months now. I love that it doesn’t taste like chemicals. It is a soft, but minty fresh taste that leaves my mouth ready to begin and end my Grind (See what I did there).My dentist had no complaints about my teeth during my last visit so I feel good about using a product made by a fellow Veteran to take care of my smile.I can’t wait to see what is next. Give Grind a try and you will like it.

The marketing made me purchased it. The flavor makes me not want to buy it again.
I brought this in hopes of a new toothpaste to replace my current favorite. However, I’m underwhelmed with the “mint refreshed”. Also, I don’t really see a benefit to using this toothpaste that isn’t already being provided by others. While I won’t throw it away and will finish using it (because the mint isn’t overpowering, but it’s really underwhelming), I will likely not purchase this again.

Weird at first but love the product!
I live by this product been using for 3 years now! If you’re switching from a big brand fluoride toothpaste, this will feel like you haven’t brushed your teeth for a while but you’ll get use to it. I know charcoal has been found to remove your enamel, but my dentist couldn’t stop raving about it once she learned I was prone to cavities.

This is one of the few more natural toothpastes that has the same kick as the chemical slop.
