Buyer's Guide: How to Choose the Best Product
Switching to an electric toothbrush removes up to 100% more plaque and protects your gums from abrasive over-brushing.
Rotary/Oscillating vs. Sonic Technology
Oscillating-rotating brush heads (Oral-B) cup each tooth and mechanically pulse and spin to break up plaque. Sonic toothbrushes (Philips/Agaro) vibrate at 30,000+ brush strokes per minute to fluidly clean between teeth.
Visible Pressure Sensors
Brushing too hard causes gum recession and enamel wear. A smart pressure sensor flashes red and automatically slows down motor speeds if excessive force is applied.
How We Tested In Our Lab
We test electric toothbrushes on dental typodont models with artificial plaque dye, measuring plaque removal percentage and bristle pressure with strain gauges.
