最近,德国柏林高级研究所的生物学家凯文·福斯特通过研究发现,刷牙不仅能清洁牙齿,还能严重破坏口腔中剩余细菌的群居生活,有可能使细菌侵蚀牙齿的能力降低。和其他许多微生物一样,口腔中的细菌生活在被称为生物膜的保护性化学基质中。这种生物膜限制了细菌的移动,因此细菌往 Recently, biologist Kevin Foster of the Berlin Institute for Advanced Study in Germany found through research that brushing his teeth not only can clean teeth but also seriously damage the colonies of the remaining bacteria in the oral cavity, which may reduce the bacteria's ability to attack the teeth. Like many other microorganisms, the bacteria in the mouth live in a protective chemical matrix called a biofilm. This biofilm restricts the movement of bacteria, so bacteria go
