The modified Streptococcus mutans strain may be so effective that it would only require one dose:
Hillman added that clinical trials would help determine if one application is all that is needed for lifetime protection. The proposed studies will involve squirting a liquid solution of the effector strain on the patients’ teeth. He said he hopes to start adult clinical trials this year.
“The ideal application would be to treat infants when their first teeth appear. Infants normally acquire Streptococcus mutans via contaminated saliva from their mother or primary caregiver,” Hillman said. “The child would simply visit their dentist for a squirt of solution on their teeth. The approach also is designed for use in older children and adults.”
