A electric toothbrush does a much better job at cleaning your teeth though. I have a basic oral B one that I can get new heads for cheaply and easily and it has a usb-c charger. It’s great honestly. I’m sure it’ll die one day but so do normal toothbrushes. I’ll crack the shell open and recycle the battery it’s not a big deal. I had a random Amazon one before that broke after a few months but the very basic “old” style electric brushes seem to last some years. The more “UI” and features it has the less it’ll last
Unless something has changed, it's pretty difficult to replace the battery in Oral B toothbrushes. Which is a shame, because they die pretty much like clockwork after about 3 years.
