Researchers at the University of Southern California have made a major breakthrough in the investigation of tooth enamel regrowth procedures.
Tooth enamel is a nonliving tissue; unlike bone, enamel does not regrow naturally in the human body.
This fact has been the bane of dentists and patients alike; previously, once enamel eroded, it was gone forever.
Lack of tooth enamel can cause sensitivity and even pain in the mouth, and make the tooth much more susceptible to breakages, decay, and other issues.
However, the team of researchers at USC have discovered that an enzyme found only in the teeth—metalloproteinase-20, or MMP-20—is a key component in biomineraliztion and the initial creation of enamel on the tooth.
