• Patented ultrasonic technology: the ultrasonic transmitter is integrated into the brush heads, allowing for direct and effective cleaning. • Efficiently removes biofilm and reduces dental plaque. • Provides superior dental hygiene without the need to scrub; simply hold the head against the teeth and the ultrasonic brush performs the cleaning. • M2 brush heads with standard shape, straight bristles, and balanced hardness, adapted for emmi-dent Platinum ultrasonic toothbrushes. • Easy attachment thanks to the 4 contact pins at the base of the head, making it easy to connect to the handpiece. • It is recommended to change the brush head every 3 months to ensure optimal cleaning, as the ultrasonic transmissibility of the bristles decreases with use.
