Coltrane had an uncontrollable sweet tooth. From “John Coltrane: Impressions Of His Life And Music”:
+++Now twenty-six, he was using heroin, smoking cigarettes, and drinking fairly heavily, gaining weight, and generally not in good spirits. In addition, his teeth hurt him constantly as a result of his inability to control his love of sweets. He consumed candy bars, other sweets, and Coca-Cola so rabidly that his teeth began to deteriorate.+++
Nice to see you back, Mary_Jo.
