Is electric toothbrush really useful?

Electric toothbrushes use high-frequency vibrations to clean teeth, which are related to the bristles' softness and roundness. If we usually from periodontitis or tooth sensitive friends, whether manual or electric, if the bristles are hard and low round rate, it is by damage to the gums. If by the friend of this kind of situation, feel the vibration of electric tooth brush big not to adapt, it is recommended to buy the manual toothbrush with high round rate and soft bristles. If our teeth are relatively healthy, I personally recommend electric toothbrushes, because most people use electric toothbrushes to clean the degree is much higher than manual toothbrushes. Choose the right bristles and the overall benefits will definitely outweigh the disadvantages.
