I was wondering why my dentist was shaking my cheek while injecting my gum with painkillers, but I didn't think much of it until I remembered that pain and tactile signals go through the same nerves, so you can feel one but not both at the same time.
I asked, and he confirmed it was exactly for this reason: to saturate the nerve with tactile signals so that pain signals cannot reach the brain.
I knew about this, but seeing it actually used by a health professional blew my mind. It is so smart 🤯
