Scientists sink teeth into identifying several new bacteria that cause dental caries

The microbial ecosystem of our body plays a vital role in its upkeep. Any imbalance in this ecosystem can cause several health problems; in our mouth, this can mean tooth cavities. Motivated by the need to find out why an increasing number of young Japanese people are reporting tooth decay, scientists from Japan examined saliva samples from university students. They discovered insightful differences in the oral microbial communities of those with and without tooth decay.
