First, the benefits:
1, cleaning capacity
It is difficult to clean the dental plaque on teeth with a toothbrush, and most people brush their teeth in an incorrect way, so the cleaning effect of teeth is greatly weakened. According to the experiment, electric toothbrush can remove more dental plaque, which is about 30% better than ordinary toothbrush, and it is also better than ordinary toothbrush in cleaning teeth.
Step 2 feel comfortable
Electric toothbrush can make people feel comfortable when brushing their teeth, because it vibrates at a regular frequency through electricity, which will be very comfortable, and it can also promote blood circulation in the mouth and massage the gums, which will make them feel very comfortable in the process.
Second, the shortcomings:
The price of electric toothbrush is much higher than that of ordinary toothbrush. In addition to this reason, there are some electric toothbrushes whose frequency is too low. Although it will make people feel comfortable, it can't play a good cleaning role.
Extended data:
note:
1. Whether it is an ordinary toothbrush or an electric toothbrush, the bristles and gum line should always keep a 45 angle when brushing. Because there is a small depression of about 3mm between the teeth and gums, only when the brush hair and the gum line form an angle of 45 can the food residue inside be completely cleaned up.
2, electric toothbrush, pay attention to turn on the switch to squeeze toothpaste, which will help the ointment to "evenly distribute" and clean the mouth more effectively. Of course, it is also possible to squeeze toothpaste on the bristles when the power is off, and still keep the power off. First "smear" toothpaste evenly on the bristles on the teeth, then turn on the switch and start brushing your teeth.
