More clues were revealed in a recent study about the microbes involved in the formation of tooth decay and cavities (dental caries). Scientists and dentists have long known about Streptococcus mutans involvement in cavity formation, but they found that another bacterial species can also be involved.

In the study researchers analyzed tooth plaque of 300 children (aged 3 to 5 years) and discovered that the bacteria Selenomonas sputigena (normally involved in gum disease) can partner with S. mutans to form cavities.

Perhaps in the future microbes or enzymes will be used to fight or suppress harmful bacteria involved in dental caries. We'll see.

From Science Daily: Dentists identify new bacterial species involved in tooth decay

Collaborating researchers from the University of Pennsylvania School of Dental Medicine and the Adams School of Dentistry and Gillings School of Global Public Health at the University of North Carolina have discovered that a bacterial species called Selenomonas sputigena can have a major role in causing tooth decay. ...continue reading "The Bacteria Involved In Tooth Decay"
