How to choose an electric toothbrush?

2.Cleaning mode: The electric toothbrush can switch the corresponding brushing mode for different oral problems, standard mode (plaque cleaning), protection mode (care for gums), sensitive mode (suitable for sensitive teeth and gums), etc.
3.Battery life: The short battery life of an electric toothbrush increases the frequency of charging, which is inconvenient for people who travel for long periods of time and long distances. Therefore, the longer the battery life, the less the user has to recharge the battery several times.
4.Zone change reminder & timer function:When choosing an electric toothbrush you should pay attention to whether it has a 30s reminder and a 2-minute automatic timer function. 30s reminder function to achieve an even brushing time for each area of the mouth, which helps users to change bad brushing habits; 2-minute automatic timer function to ensure that the dental recommended time is reached every time you brush.
