The world's first human trial of a drug that can regenerate teeth will begin in a few months, less than a year on from news of its success in animals. This paves the way for the medicine to be commercially available as early as 2030.
The one I got was one of the "Sonic" ones or whatever, that vibrates really quickly. It just didn't do it for me. It always felt like more hassle than it was worth because it's so different than a regular toothbrush.
I also had one that was battery powered, not rechargeable or anything, so I had to keep alkaline batteries around...
Oh, yea, the vibrating ones don't work and the ones with batteries are too much bullshit trouble.
I don't know about easier, because the electric toothbrush does all of the work, but It's comfortable enough to just smash a normal toothbrush around your mouth, and far, far less effective at cleaning your teeth.
A manual toothbrush moving fast can brush 600 times a minute; electric toothbrushes brush almost 50,000 times per minute because the brush head is oscillating.
