They are designed to help remove external surface stains and make teeth look cleaner and naturally brighter. Hydroxyapatite may also improve surface smoothness and optical brightness. They are not a bleach and will not provide the same dramatic shade change as a dedicated whitening treatment.

Hydroxyapatite is a calcium-phosphate mineral similar to the mineral naturally found in tooth enamel. In oral-care formulations, it can deposit on enamel and support remineralisation of early surface mineral loss.

The formula is designed to use certified-organic agricultural ingredients wherever practical, together with necessary mineral and naturally derived ingredients. The final product should only be called certified organic after formal certification has been completed.

The formula uses plant-derived ingredients, botanicals and minerals. Some ingredients, such as decyl glucoside and zinc citrate, require controlled processing. A more accurate description is “made with certified-organic, mineral and naturally derived ingredients.”

TGC avoids positioning a spit-out toothpaste as a supplement. The formula is designed to be gentle and microbiome-conscious, but claims that it improves gut health, brain health or pineal-gland function should not be made without direct clinical evidence on the finished product.

The children’s formula must be separately developed with age-appropriate essential-oil levels, flavours and directions. The adult peppermint-and-clove formula should not automatically be used for children without a qualified safety assessment.
