they never sell, but they always reccommend it buying it online or in store, they arnt financially benfitting from it, at leas the most recent ones. dentist will know if your manual brushing isnt sufficient enough, despite you using a proper technique.

Never had a dentist try to sell me a toothbrush. In fact, I get given a manual one every time I leave. Which I use for cleaning around the taps in the bathroom. But they are always glad I'm using an electric brush. My kids (both under 10) use them too, after they learnt how to do it manually properly (just in case).

Not American btw.

Could you share a bit about why you prefer not to use it? 🙏
