It’s dandy for your teeth

Dr. Reilling was my first dentist. Now I understand why his advice to me was always “brush-a-brush-a-brush-a.” It’s part of the song that Bucky Beaver sang to promote Ipana toothpaste. (Yes, Dr. Reilling was even older than me; I think Ipana was out of the market even then.) See a sampler of things for an image of Bucky and a link to an audio file (admittedly scratchy) of Bucky jingling.
