Product Info

Coastal Crush, Fluoride-Free Whitening Toothpaste

Coastal Crush is a fluoride-free hydroxyapatite whitening toothpaste with pineapple and coconut that brushes like a short vacation.

  • DROXY™ formula. Micro and nano-hydroxyapatite (n-Ha) work with theobromine and xylitol to remineralize and rebuild enamel while whitening gently, the smarter way to care for your smile.
  • Functional flavor. Pineapple and coconut with Vitamins K2 and D3. Vitamin D3 helps your body put calcium to work, and K2 helps guide that calcium to your teeth to support strong enamel.
  • Made for every smile. Powerful but never harsh, gentle on sensitive teeth, and loved by the whole family, even the kids.
  • Clean ingredients. Fluoride free by choice, with no peroxide, parabens, sulfates (SLS), artificial sweeteners, colors, or flavors.

Rise. Grind. Repeat.

Way better than I expected

Got to try it before it was for sale. Pineapple and coconut in toothpaste sounded a little crazy not gonna lie 😂 but somehow it works. It’s fresh without tasting like every other toothpaste. This one’s probably my favorite so far.

THE GRIND GUIDE

Does it actually taste good?
Better than good. Grind comes in nine crave-worthy flavors, from Mint Chip to Berry Dip'd, so brushing becomes the best two minutes of your day. No chalk, no medicine-cabinet aftertaste, just flavor you'll look forward to.
Will it actually whiten my teeth?
Yes. Grind gently lifts and polishes away surface stains while dual hydroxyapatite rebuilds enamel, so your smile gets brighter without grit, bleach, or sensitivity. Whitening that works with your teeth, not against them.
Is it fluoride-free?
Completely. We skipped fluoride on purpose and built the formula around hydroxyapatite, the same mineral your enamel is made of. You get real strengthening the modern way, safe for the whole family.
Is it safe for sensitive teeth?
It's made for them. Hydroxyapatite seals the tiny tubules that cause sensitivity, calming the ache at the source instead of just masking it. Most people feel the difference within a couple of weeks of daily use.
Do I really not have to rinse?
Nope. Grind is a low-foaming formula designed to be left on, so the hydroxyapatite stays on your teeth instead of going down the drain. Spit, smile, go. Rinsing is optional if you prefer.
Will my kids actually use it?
That's the whole idea. Flavors like Coastal Crush and Purple Pop make brushing something kids ask for, and the fluoride-free, swallow-safe formula means you don't have to hover. One paste the entire house actually likes.
Is it vegan and cruelty-free?
Yes. Grind is vegan and never tested on animals, and it's free from sulfates, parabens, artificial sweeteners, and fake dyes or flavors. Clean ingredients you can feel good about twice a day.
