This toothbrush combines the efficiency of an electric toothbrush to the softness of a manual toothbrush. The sonic technology acts by vibration of high frequency bristles to more easily eliminate the plaque in the inter-dental spaces difficult to access, while remaining gentle for the gums. The Sensitivity brush has soft conic bristles for a gentle brushing.The toothbrush is compact and without pedestal, nomadic and lightweight, silent and has a long battery life (1 charge once a month is enough). It is suitable for those wearing braces and dentures.The timer is programmed to indicate the 2 minutes of brushing recommended by dentists. Every 30 seconds it stops to indicate that you need to change the brushing section. The bristles are made of Tynex® and cut with a Diamond Technology® to protect the gums and enamel.
