Toothbrush timer

Two minutes is the standard recommendation from essentially every dental association. Studies that actually measure it tend to find people brush for somewhere around 45 to 70 seconds while believing they brushed for two minutes.

Thirty seconds per quadrant is the easiest way to spend it. Most people over-attend to the front teeth they can see and under-attend to the back molars and the inner surfaces.

Pressure matters more than speed. Hard scrubbing wears enamel and irritates the gum line without cleaning better.
