Coswell's toothpaste developer, accidentally under the opportunity of prosthetic limb reconstruction, applied to the human body and body after a high degree of integration, to bring convenience and Gospel inspiration to patients. So the germination of toothpaste can also be bioremedied to fill the tooth demineralization and wear of the tooth surface, thus effectively preventing teeth due to daily use, wear and tear caused by various problems.

So he found the highly authoritative LEBSC laboratory in the field of bone remodeling and bone mineralization at the University of Bologna, Italy (which has a history of more than 30 years), and exchanged his ideas in detail with Professor Dr. Norberto Roveri, the head of the laboratory, and was highly recognized by the professor.

Ultimately, they worked together to develop a special patented formula for repairable enamel nanoparticle crystals, Microrepair ("China Invention Patent: ZL 2006 0055372.8 International Patent Publication No. WO 2007/137606A1 Invention Name: Bioactive Hydroxyapatite Nanoparticles Substituted with Carbonate and Their Preparation Method and Compositions Containing it")

After many years of clinical research, it has been proved that the patented ingredient microrepair < bionic restoration microcrystal in Belida toothpaste can effectively restore enamel and reconstruct the natural tooth layer on the surface of teeth. The results were published in 2010 in the most authoritative journal of clinical Periodontology in the European Union.

At present, Biorepair has become a toothpaste that can really repair enamel on the market, and has been approved and recommended by many dentists.
