Emmi-dent E2 Replacement Brush Heads (2 Pack)
The Emmi-dent brush head contains a specially patented ultrasonic microchip. It is recommended that you replace your Emmi-dent ultrasonic toothbrush head every three months. A worn Emmi-dent brush head transmits less ultrasound through its bristles and therefore does a less effective job of cleaning your teeth.
