Description
Mister Rogers arrives with a tube of toothpaste which he shows before inviting viewers along on a visit to his dentist. Before leaving, Mister Rogers heads to the bathroom to brush his teeth. At the dentist's office, Mister Rogers receives a check-up from Dr. Doug Jackson and his hygienist, Lisa Gjebre. Lisa and Dr. Jackson demonstrate various tools used for a dental check-up. Afterwards, Mister Rogers talks with a young dental patient named Joe. Returning to the house, Mister Rogers takes out a puppet which he uses to explain that people should not bite other people. In the Neighborhood of Make-Believe, Neighbor Aber sings It's the Style to Wear a Smile as Princess Zelda is looking for the Director of Research, Lady Aberlin. Still looking like a tiger, Lady Aberlin appears from behind the tree but goes unrecognized by Neighbor Aber and Princess Zelda. At the castle, Queen Sara reveals that Lady Aberlin will be gone for a "limited period of time." Back at the house, Mister Rogers sings It's the Style to Wear a Smile and talks about the best feelings are the ones that come naturally.
