Why did the children not care to brush their teeth or wash their mouths properly?

Answer: The children would wake up on listening the jingling thud of the pader in the morning. Then
they used to run to meet and greet him. In the process, they did not even care to brush their teeth or wash their mouths. To support this act, the narrator made the point that a tiger never brushed his teeth and a cup of hot tea could wash and clean up everything so nicely.
