After an only partially successful operation on his right shoulder in 1972, Heifetz ceased giving concerts and making records.
His prowess as a performer remained, and he still played privately until the end—but his bow arm was affected, and he could never again hold the bow as high as before.

Heifetz taught the violin extensively, holding master classes first at UCLA, then at the University of Southern California, where the faculty included renowned cellist Gregor Piatigorsky and violist William Primrose.
For a few years in the 1980s he also held classes in his private studio at home in Beverly Hills.
His teaching studio can be seen today in the main building of the Colburn School and serves as an inspiration to the students there.
During his teaching career Heifetz taught, among others, Erick Friedman, Pierre Amoyal, Adam Han-Gorski, Rudolf Koelman, Endre Granat, Teiji Okubo, Eugene Fodor, Paul Rosenthal, Ilkka Talvi and Ayke Agus.

During the last ten years of his life, Heifetz visited Hans Benning at Benning Violins for maintenance on his 1740 Guarneri violin.
