The secret of beautiful, naturally white teeth is healthy enamel, . . . smooth, semi-transparent, revealing the natural whiteness of the dentin beneath. When it becomes microscopically scratched or subject to acid attacks from plaque or foods, tooth enamel loses its gloss and transparency and becomes cloudy and easily stained, making the teeth dull and discolored. By constantly replacing essential tooth mineral, Sangi's nano<mHAP> protects against surface scratching and loss of mineral density, and keeps the enamel smooth and translucent, restoring and maintaining the natural whiteness of your smile.
Many toothpastes contain stain removers : some of SANGI's do too. And many contain abrasives, to remove stains by polishing : but that's something SANGI's toothpastes do not do. The key point about SANGI's nano<mHAP> is that, being almost the same substance as tooth enamel, it fills and repairs microscopic scratches on the tooth surface to which stains readily attach, thus reducing the possibility of tooth staining. For smokers and red wine or tea or coffee lovers, for whom special care is required, stain removers are included in some of SANGI's toothpastes. But it's repair of the enamel surface - to a smoothness you can feel for yourself - that offers the best and most lasting protection against stains.
SANGI's nano<mHAP>, known as 'Medical Hydroxyapatite' in Japan, was approved as an anti-caries agent by Japanese health authorities as early as1993. Based on data from laboratory research and field trials, they recognized three ways in which it helps reduce tooth decay: (1) by adhering to and helping remove decay-causing bacteria and dental plaque, (2) by filling and repairing microscopic fissures on the tooth surface which form a breeding ground for plaque-forming bacteria, and (3) by remineralizing areas below the tooth surface from which mineral has been dissolved out by acids from plaque and foods - areas known as 'incipient caries' and which can lead to tooth decay unless the lost mineral is restored by our saliva or from other sources.
Teeth at all ages require a constant supply of mineral, but especially children's teeth. In newly erupted teeth, the enamel is still not completely mineralized; it relies on a constant supply of calcium and phosphate from saliva to reach full mineral density and strength. This makes children's early teeth especially vulnerable to acid attack and development of caries. By augmenting saliva's natural supply of tooth mineral, SANGI's ingredient nano<mHAP> supports the maturation of children's teeth, and protects against tooth decay - as shown by clinical trials in Japanese primary schools over a number of years. Some of SANGI's products, including our mouth rinse and children's toothpaste, contain the natural sweetener xylitol, for additional anti-caries protection. But fluoride is not used in any of SANGI's products, because it isn't necessary. Nano<mHAP>, by supplying tooth mineral, directly achieves the same level of remineralization as fluoride, which relies on external sources of mineral, indirectly does.
One of the first things you notice about SANGI's toothpastes - in addition to the incredible smoothness of your teeth - is how clean they make your mouth feel. And this feeling of cleanliness lasts for hours. It's the first thing people comment about. Why? Well the smoothness comes from surface repair, remineralization filling in microscopic scratches on the enamel surface that are a harboring place for plaque. Nano<mHAP> also gathers up and removes plaque and plaque bacteria from the mouth during toothbrushing, in particular Mutans streptococci, the major decay-causing family of bacteria, for which it has a special affinity. The result is return to a healthier, more favorably balanced oral flora, while at the same time making it harder for bacteria to settle on the steadily restored, smooth surface of the teeth.
Unpleasant breath is the one thing your best friends won't tell you about. And it's something you often don't notice yourself. Sometimes it can result from systemic causes, but breath problems originating in the mouth can definitely be helped by the right type of toothpaste. Not simply one that masks oral odors with strong flavor, but a toothpaste which (1) eliminates factors causing the odor, such as plaque-forming and periodontitis-related bacteria, and (2) absorbs oral odors when they occur. SANGI's ingredient nano<mHAP> does both. It adsorbs and removes not only caries- and periodontitis-related bacteria, but also a number of nasty-smelling odors - the malodorous gases that components of plaque and periodontitis produce.
Another remineralizing function of nano<mHAP> is to seal and form a coating over dentinal tubules in places where receding gums or a thinning of the tooth surface have left the dentin unprotected, thus exposing the tiny tubules that lead to the tooth nerve to external stimuli such as heat and cold. The pain-killer potassium nitrate, acting at the nerve surface, can provide immediate pain relief by blocking transmission of these external stimuli when they reach the tooth nerve. But it doesn't solve the problem of ongoing exposure to such stimuli at the tooth surface. In contrast, nano<mHAP> acts to resolve the problem by forming a new enamel coating over areas of exposed dentin, thereby sealing the tubules and preventing access of stimuli from the oral cavity to the nerve deep within the tooth.
As age catches up with us, our immune system weakens and the flow and mineral content of our saliva begin to decline. Dry mouth is common in elderly people, especially through the night, while opportunistic infections from microbes such as Candida tend to increase with age. In addition, the acid neutralizing functions of our saliva tend to weaken, increasing the risk of caries. Regular daily use of nano<mHAP> toothpaste, by supplementing the natural mineral concentration of the saliva and supporting its neutralizing and remineralizing role, helps to maintain the mineral density and natural whiteness of older persons' tooth enamel, keeping it healthy and young. At the same time, nano<mHAP> helps eliminate harmful microbes, including Candida, resulting in a more favorably balanced oral flora and the maintenance of an odor-free, healthy environment in the mouth.
One of the features of hydroxyapatite is its ability to adhere to and gather up protein. In the oral cavity, this chiefly means bacteria and plaque fragments scrubbed off the teeth during toothbrushing. Decay-causing S.mutans bacteria have a special affinity for hydroxyapatite, the substance of our teeth, replicating only on the tooth surface, which they colonize to form plaque. SANGI's nano<mHAP>, being almost the same substance, selectively gathers S.mutans bacteria during toothbrushing, facilitating their removal from the mouth on rinsing out. It also gathers up and helps to remove periodontal disease-related bacteria such as P.gingivalis and A.cometans, and even the fungal microbe Candida. But nano<mHAP> doesn't kill microbes, good or bad, like an antiseptic, and therefore no allergy-causing toxins are produced. Instead it promotes healthy gums by contributing to maintain a balanced microbial flora in the mouth.
