Can You Read an Account of a Tooth Explosion?

The first account I'm aware of came from 1817 and I happened to a patient from Springfield in Mercer County, Pennsylvania. He's living at this present time and has vivid recollection of the distressing incident. All at once a sharp crack like a pistol shot bursting his tooth to fragments gave him instant relief. At this moment he turned to his wife and said, my pain is all gone.
