  • The first American to patent a toothbrush was H. N. Wadsworth and many American Companies began to mass-produce toothbrushes after 1885
  • In 1873, Colgate mass-produced the first toothpaste in a jar
  • 1901 The ‘Indexo’ toothbrush is made entirely of rubber, which has been shaped to fit over the index finger
  • Celluloid plastic brush handles appeared during World War I, when every bone available was needed to make soup
