Dentists have uncovered a breakthrough in oral health by identifying a previously unknown bacterial species linked to tooth decay. Tooth decay, a common dental woe, is primarily caused by the activity of certain bacteria in the mouth. In this latest discovery, dentists pinpointed a new bacteria, expanding our understanding of the complex microbial community within the oral environment. These findings enhance our grasp of the mechanisms driving dental deterioration and may pave the way for targeted interventions to combat cavities.
