Two minutes, twice a day, done right. Here's the full technique — angle, motion, and the spots everyone forgets.
Soft-bristled brush, a pea-size dab of fluoride toothpaste on the bristles. (Rice-grain for under-3s.)
Tilt the bristles halfway between the tooth and the gum, so they sweep the gumline where plaque hides.
Gentle, tooth-sized circles — never a hard side-to-side saw. Let the bristles do the work.
Outer, inner, and chewing surfaces of each quadrant — about 30 seconds apiece.
A few light strokes from back to front clears bacteria and freshens breath.
Spit out the excess but skip the water — leaving a little fluoride behind protects longer.
Most people bail at 45 seconds. Hit start, follow the highlight, and give every corner its fair share.
