The chemical reportedly wipes out all bacteria that cause cavities in just 60 seconds.
It could turn toothpaste, mouthwash and chewing gum into super cleansers that could get rid of the underlying cause of tooth decay.
The chemical, which has been called Keep 32 after the 32 teeth in a human mouth, is now undergoing human trials after seven years of testing.
Experts say it could be on the market in 14 to 18 months.
