On a different line of research, Jeffrey Hillman from the University of Florida developed a genetically modified strain of "Streptococcus mutans" called BCS3-L1, that is incapable of producing lactic acid--the acid that dissolves tooth enamel--and aggressively replaces native flora.
On a different line of research, Dr. Jeffrey D. Hillman has developed a genetically modified strain of "Streptococcus mutans" which could be available in 2012-2013. The new strain, called BCS3-L1, is incapable of producing lactic acid, which dissolves tooth enamel, and aggressively replaces native flora.
