My father was meticulous about his teeth cleaning. Brushing, flossing and monthly check up was norm for him, even ducking between his busy schedule.
He always had time for breakfast and most dinners with family, morning Uchideshi chorei (朝、礼) literally translates to morning / courtesy
and always, always brushing his teeth thoroughly after each meal.
There is a ritual my yoga teacher made us all do call Mauna. It means cleansing for a short period of time, like not speaking. This particular one I practiced a lot was to "clear the mouth". Aside from the removing the food debris, gossiping really tarnishes your mind, starting from the mouth.
When yoga practice commences- all students have washed their hands, feet and their mouths. If possible bathing is preferred. But this shows the importance of cleansing certain areas more so than others.... (o^^o)
I was always amazed by how mindful and dedicated he was to even the
most seemingly ordinary things. I guess as the saying goes, cleanliness is godliness (o^^o).
