Frequently Asked Questions

Here are some ideas to help. 



There are 60 grams of powder in a jar. So, if you use the ‘sprinkle over your brush’ technique to apply the powder to your brush, there will be around 240 uses.

If one person brushes twice daily, we can approximate 3 months

Our products are 100% safe to use during pregnancy , but we always advise to consult with your health practitioner.

A toothpaste formulation requires the use of many ingredients that have no impact on your oral care. Like surfactants , preservatives , solvents , stabilisers, thickeners for texture , flavour , stability & shelf life

A paste that flows out of a tube needs water, flow (viscosity) modifiers, and paste stabilizers that are all chemicals.

We use minimum , raw in the original form that are all beneficial & active, whilst eliminating ingredients that we don`t need. 

The RDA was simply a test designed in 1976 to determine abrasion in the laboratory but did not correlate to abrasion in the mouth. In 1995, RDA became the international standard for abrasion measurement. Tooth wear has many factors.

For example diets high in acidic beverages and foods, bruxism, aggressive or improper tooth brushing, low pH of the oral cavity ,acid reflux, GI disorders, bulimia nervosa,  and oral hygiene habits are all contributing factors.

Erosion is a common cause for tooth wear, which can be broken down to two primary causes − intrinsic factors and diet. Intrinsic factors can often be difficult to manage, as these are acids caused by physical limitations. Tooth structures can be chemically eroded by the acids resulting from gastroesophageal reflux or prolonged vomiting. External factors such as a diet play a tremendous role in the wear of tooth structures. An acidic diet will also chemically destroy the tooth structures, particularly beverages that are often swished in the mouth or sipped repeatedly over a longer period of time.

Abrasion is another factor in tooth wear.

The Mohs Hardness Scale is a set of ten reference minerals (numbered 1 through 10) that are used to determine the relative hardness of minerals and other objects

Studies at the atomic level have revealed that human tooth enamel is incredibly complex. It consists of tightly bunched together, oblong-shaped mineral crystals that are a thousand times smaller than a strand of your hair.

Tooth enamel is mostly hydroxyapatite, which is a mineral form of calcium phosphate. The apatite group of minerals scores a five on the Mohs hardness scale; which makes enamel the hardest biological material.

Tooth enamel is harder than steel, but a lot more brittle. 

Baking soda rates 2.5 on the Mohs scale of hardness—just above talc and well below traditional blasting abrasives such as silica .

Calcium Carbonate rates 3 

There are 3 forms of Hydroxyapatite that exist.

Natural Hydroxyapatite — a naturally occurring mineral form of calcium apatite (calcium, phosphorous oxygen) that makes up most of our bones. The sources are mammalian,fish bone or scale, shell, limestone. These particles of HAp are slightly bigger than nano .Natural can often be referred to as MCHA or Micro made from bone.

Nano Hydroxyapatite —Nano-hydroxyapatite has been created in a lab, atomized into fine powder particles. Synthetic nano-hydroxyapatite mimics the size of natural dentinal hydroxyapatite or enamel apatite(Pentacalcium hydroxide triphosphate).

Biomimetic Hydroxyapatite- Synthesised materials that mimic the natural hydroxyapatite of enamel and dentin.

NATURAL HYDROXYAPATITE- We use the finest particle size our team can mechanically produce, which is right around 70 micrometers.

In our view, nano-HA FACES 2 challenges:

  1. Its extremely small particle size facilitated easy migration throughout the body, including crossing the blood-brain barrier and penetrating cellular structures, raising concerns about safety as emerging literature indicated.
  2. Nanoparticles are synthetically manufactured, lacking natural derivation.

NANO HYDROXYAPATITE- According to this article  Hydroxyapatite (nano) is fully synthetic and inorganic.  The available information indicates that HAP-nano in needle-shaped form is of concern in relation to potential toxicity. Therefore, needleshaped HAP-nano should not be used in cosmetic products. 

This safety evaluation only applies to the hydroxyapatite (nano) with the following characteristics:

- composed of rod-shaped particles of which at least 95.8% (in particle number) have an aspect ratio less than 3, and the remaining 4.2% have an aspect ratio not exceeding 4.9;

- the particles are not coated or surface modified.

Suggested usage is 

Toothpaste at concentrations up to 10%
Skin products  up to 5%
Oral hygiene products > Mouth wash  at concentrations up to 0.465%

Why do so many people “assume” baking soda is extremely abrasive?

It’s because the particles are large and have sharp edges, so it “feels” gritty when you touch it.

Mohs Hardness of materials (remember this is an ordinal scale, so there is no mathematical formula of consistent distance between each number):

  • Tooth enamel = 5
  • Tooth dentin/root = 3
  • Baking soda = 2.5
  • Hydrated silica in toothpaste = 5-7

Baking soda “feels” much more gritty than regular toothpaste (which usually has hydrated silica as the abrasive) because the particles are larger, and the edges are rough. Whereas silica particles are more round, smooth, and many times smaller.

So baking soda “feels” more abrasive – but it’s not.

The American Dental Association has published their RDA (Relative Dentin Abrasivity) to measure the abrasiveness of various toothpastes. The RDA abrasiveness categories are:

  • Low 4-70 (plain water is 4. Baking soda is 7.)
  • Medium 70-100
  • High 100-150
  • Harmful 150-250

The FDA limits abrasiveness to a maximum of RDA 200.
