Regenerated silicon can inhibit harmful oral flora with weak alkaline pH value, fill exposed dentinal tubules, release minerals such as calcium and phosphorus needed by teeth to combine with enamel, and resist external invasion.
The recovered silicon is used in toothpaste. It is a nonmetallic inorganic biomaterial with the strongest biological activity at present, and has won more than 40 major awards, such as China Patent Silver Award and the first prize of "National Science and Technology Cup" of Chinese Academy of Sciences. Through the application of breakthrough nanotechnology, the specific surface area of 1g recycled silicon can reach 576m2, which can cover every corner of teeth. By adding recycled silicon, Haode toothpaste can not only prevent dental caries by forming a weak alkaline environment, but also improve the hardness of enamel and induce periodontal tissue regeneration through the penetration of calcium and phosphorus ions.
