We are commonly told to spend a half-minute on brushing the teeth of each quarter of our mouth. I imagine that this idea entails having one central incisor in each quarter. Do people really divide their mouth into these even quarters for cleaning their teeth? Personally I divide mine into twenty unequal regions (2 × 2 + 2 × 4 × 2):
Central (incisors and canines),

  • upper jaw, lower jaw (2)

  • faces: front, back (2)

Side (premolars and molars),

  • upper jaw, lower jaw (2)

  • faces: front, back, top, far-end (4)

  • left, right (2)

I wonder how others do it. In interviewing my children I found that they too have their own systems that do not comfortably divide into these mouth-quarters.

I do now, in fact, divide my mouth into quarters (upper left arcade, upper right arcade, lower right arcade, lower left arcade) - mostly because my electric toothbrush divides its 2-minute runtime into 4 30-second chunks. I think before I had an electric, I used to just do top then bottom (side, side, middle), but it's been a while.
