Born in Vermont, Wells was educated in Walpole, New Hampshire before studying dentistry in Boston. After obtaining a degree, Wells set up a practice in Hartford, Connecticut, with an associate named William T.G. Morton, who would become famous for his use of ether as an anesthesia on October 18, 1846. Wikipedia
