Flavor

How does it taste? 

The light Clean Mint flavor is powered by natural peppermint oil and isn’t too strong. The Sodium Glutimate provides foam without any risks of irritation. The clean mint formulation is also significantly less watery than most other natural toothpaste formulas. Minty enough to freshen your breath without any harsh burn. 

Uncomplicated ingredients

When it comes to products that go in and on your body, fewer ingredients is better! YAYASHI Clean Mint toothpaste is the simplest solution for a natural toothpaste with ingredients proven to effectively fight cavities. Many natural toothpastes remove all cavity fighting ingredients and leave you with less protection than other alternatives. YAYASHI is formulated with 7.5% nano-hydroxyapatite which has been shown to be just as effective as fluoride at preventing cavities. Free from SLS, glycerin, and artificial colors, you won’t find any cringe worthy ingredients.

Ollie only has 9 ingredients (two of which are water and coconut oil), each with a specific purpose. Here’s some keys to the formula:

Nano Hydroxyapatite – Very few toothpastes contain hydroxyapatite, much less 7.5%. The nano particles are small enough to fit into and heal small cracks and gaps within your teeth and the concentration means there will be enough to do the job.
Potassium Gluconate – a potassium salt compound that helps control tooth sensitivity.

More information

Why 7.5% matters: Most studies which test the effectiveness of hydroxyapatite use a 7.5% formula. This concentration is the gold standard for cavity protection.

“HAP particles resemble naturally occurring enamel crystals. HAP particles have been shown to bind to the damaged enamel surface and fill in the porous surface irregularities in order restore the surface integrity”

There’s one key ingredient that’s not in your toothpaste: Its called Hydroxyapatite.

HAP (Hydroxyapatite) is the natural form of calcium your body uses to repair teeth. It works by filling small gaps and cracks on your teeth, binding to the surface to make them stronger, less sensitive, and appear whiter.

Cavity Resistance: It protects against cavities, matching fluoride’s effectiveness.

Less Sensitivity: It fills in tooth surfaces, blocking nerve access for better sensitivity relief.

Repair Cavities: It can reverse small cavities by filling cracks in teeth.

Whiter Teeth: It smooths teeth surfaces, naturally enhancing whiteness.

Fluoride free cavity protection 

We help prevent cavities by strengthening teeth with a durable protective layer of Hydroxyapatite (HAP).
As the natural substance that composes your teeth, HAP effortlessly repairs tooth enamel surfaces.
Acting like a vitamin for your teeth, HAP is safe, non-toxic, and perfectly suited for kids, pregnant women, and anyone seeking fluoride-free oral care.
