What should we pay attention to when choosing an electric toothbrush?

1. Look at the labels and try to buy electric toothbrushes with complete label information through formal channels. Avoid buying "three Nothing" products without product name information, brand model and warning instructions.

2. Choose the right type of electric toothbrush according to the user's age and dental condition. Children should choose children's electric toothbrush. If the user's teeth are sensitive, the brush head with soft bristles can be selected to reduce the damage to teeth and gums. Try to choose products that can provide a variety of working modes. In the initial use, it is not suitable to use strong working mode. Start from soft working mode, so that the teeth can have a period of adaptation. To fully consider the size of the user's mouth, the purchase of brush head should not be too large. If the brush head is too large, it will be difficult to move flexibly in the mouth and not be able to thoroughly clean the different positions of the teeth.

3. Recognize functions, pay attention to the functions of electric toothbrush, such as intelligent time reminder function, pressure sensing function, low battery reminder function, etc. The length of brushing time is directly related to the cleaning effect of teeth, so some electric toothbrush products add a time reminder function, generally prompt users to change the position of brushing every 30 seconds, and ensure that users brush their teeth for no less than 2 minutes each time. Some users can't control the pressure the toothbrush puts on their teeth. Too much pressure can cause bristles to wear down your teeth and damage your gums. Therefore, some products have added the pressure sensing function, which will automatically reduce the vibration frequency of electric toothbrush when detecting too much pressure on teeth, reducing the damage to teeth. Some electric toothbrushes will be reminded of low battery when the battery is low, such as warning light flashing, warning sound, etc., to prompt users to charge in time.

4. Vibration frequency: Electric toothbrush can often clean teeth at a deeper level with the help of ultrasonic wave caused by the friction between toothbrush hairs and teeth and motor vibration. Ultrasound cannot be seen or felt, and its function has yet to be determined. So the only thing you can pick and choose is the amount of friction between the brush and the teeth. The higher the vibration frequency of a soft-bristled electric toothbrush, the cleaner the brush can be interpreted. It is generally recommended to select products with vibration frequency of 3000 times/min.

5, battery life, three days charged electric toothbrush, who use who know, who will understand the pain. Waking up in the morning and realizing your electric toothbrush won't open is not an understandable breakdown. Therefore, rechargeable battery life, must be concerned about. Slightly similar to a better electric toothbrush, it will last at least 14 days (2 minutes, 2 times a day). There are better ones that are 20 or even 30 days old or more, but the prices are a little prohibitive.
