5 reasons why dentists love nHa
Degraded tooth enamel leads to decay and rot. Problem is: Tooth enamel is one of the only tissues in your body that cannot repair itself from within. That's why remineralization, the process of naturally repairing tooth enamel, is the most critical quality in a toothpaste.
We use a dentist-backed fluoride alternative called nano-hydroxyapatite, which is clinically proven to be just as effective as fluoride -- if not more so -- at remineralizing teeth. The difference is that nHa rebuilds enamel and dentin with the very compounds that naturally make up your teeth, while also offering additional benefits for sensitivity, plaque reduction, and whitening. No wonder nHa is quickly becoming the first-choice ingredient for daily preventative oral care.

1
The stuff teeth are made of
Teeth are the hardest structure in the body, and they're made of hydroxyapatite, calcium, and phosphate. Nano-hydroxyapatite is a microscopic derivative (hence the "nano") of hydroxyapatite, the natural mineral in your teeth and bones that combines with calcium and phosphate to make them strong. nHa was developed in the 70s by NASA when fluoride wasn't doing enough to help astronauts' tooth degradation in space. NASA scientists shrunk the hydroxxyapapitite compound so it could be applied in the microscopic dental setting -- and they found it made teeth stronger for longer on earth and beyond!

Remineralizes enamel + dentin
The nHa in duo toothpaste easily bonds with its natural counterparts to replenish and heal degraded tooth structure. Enamel is remineralized by penetrating porosities to replace dissolved calcium and phosphate and ultimately forming a new layer of enamel. Dentin is remineralized by penetrating the collagen matrix and providing a scaffold of calcium and phosphate.


3
Reduces sensitivity
Other methods of decreasing sensitivity, such as the potassium found in Sensodyne, only patch the problem of sensitivity by soothing nerves that send pain messages to the brain. nHa directly addresses the cause by plugging open dental tubules -- the access points to nerves -- and preventing painful stimuli from reaching those nerves in the first place. nHa also reduces hydrodynamic sensitivity by protecting the pulp from pressure changes.
4
Fights plaque
nHa prevents plaque formation by binding the bacteria before it reaches the teeth and periodontal tissues and preventing bad bacteria from forming a direct attachment to the tooth. nHa has been found to reduce biofilm as effectively as the antimicrobial mouth rinse Chlorhexidine without disrupting the oral biofilm with nonspecific causative agents. That means that nHa is as tough on plaque as medicated mouthwash without destroying all the good bacteria in the mouth as well.

5
Naturally whitens
nHa is naturally white and increases the brightness and whiteness of the tooth surface by remineralization, which also adds to the smoother and glossier appearance. nHA’s effect on whitening is physiological rather than mechanical or chemical, which means it doesn't strip enamel or have the caustic effects of peroxides, which increase dental sensitivity and harm the oral microbiome. For patients that do use peroxide whiteners, the concurrent use of nHa toothpaste has been proven to reduce associated sensitivity.
