Oh no, what have I gotten myself into.. : )
I'm left handed. I always put toothpaste on the brush with my right hand. Brushing is done first with the left hand and then switching to the right. I think. Wait, now I gotta go brush my teeth again to make sure.
Okay. The switch actually takes places immediately after I "water" the paste, and before I get the brush onto my teeth. It's more like a handoff. Then as I brush with my right hand, my left hand turns off the water.
Dang. I never thought about HOW I brush before.
You are OK. No injuries so far. :^)
