This helped me a while back when I hurt my dominant hand and was unable to brush my teeth. Luckily, I was already comfortable brushing my teeth with my non-dominant hand. I also noticed that my teeth felt cleaner when I brushed with both hands. I realized that I was stuck in a pattern of only brushing a certain way with one hand, and switching it up made me teeth feel cleaner.
Edit: yeah, I realize now I could have worded the title better. I didn't mean to hold the toothbrush with BOTH hands at the same time.
