Years ago, there was the uk.d-i-y contest between three outstanding diy tools.
Normally ye could say one for different uses, but for insanely brushing teeth - well, ye have choice!
In what way?
The Oral B has a brush at the end which rotates one way and then the other. The Philips brush is fixed to the shaft. The shaft twists one way and then the other very rapidly. If the head touches your teeth it makes a noise.
My newsreader truncated the heading so I expected this thread to be about water jet cutters. Which would indeed solve any plaque problem.
