Sold! Dual-action electric toothbrush (your link appeared to be simply rotating) for around $30 here.

Is there reason to believe that dual action is better than rotating?

I based that on:

Meta-studies (1) (2) identify this as specific to rotation-oscillation action, with improvements of 20% in gingivitis and plaque over manual.

That'll do me. Add to cart.

I used to have an electric toothbrush but started just buying normal brushes when it broke. Since evidently they are useful things I'm buying an oral irrigator and a rot/osc electric brush.
