MacNaughton was married with a daughter in Grand Rapids, Michigan when her husband died in 1876. Determined to become a dentist to support her family, she graduated from the University of Michigan in 1885 and returned to Grand Rapids to practice.
She became active in the women's suffrage movement, and eventually moved to Washington, D.C. in the 1890s to become more involved. She pushed for legislation that provided civil liberties to women and campaigned for suffrage for three decades. While in D.C., she set up a dental practice that focused on treating women and children.
