Nanoscale analysis reveals a way to prevent tooth erosion caused by carbonated drinks
Schematic diagram of the workflow. Credit: Biomaterials Research (2024). DOI: 10.34133/bmr.0103 A Korean research team has previously used nanotechnology to visualize and scientifically prove the negative effects of carbonated drinks such as cola on dental health, but now they have demonstrated the effectiveness of these drinks in preventing tooth damage. The mechanism of this method was identified. A team led…
