Dr. Irwin Smigel, a pioneer of aesthetic dentistry who brightened the smiles of celebrities like Elizabeth Taylor, Tony Bennett, Jimmy Fallon and Bruce Willis, died on Monday at his home in Manhattan. He was 92.
The cause was complications of pneumonia, said his son, Robert Smigel, a comedian and screenwriter and the voice of the puppet Triumph the Insult Comic Dog.
Working from his office on Madison Avenue, Dr. Smigel (pronounced SMY-gell), a second-generation dentist, advanced two techniques that transformed the appearance of teeth in countless patients beginning in the 1970s.
