Electric toothbrush purchase guide
1、 Classification of electric toothbrush
Rotary toothbrush
The principle of rotary toothbrush is simple. It relies on the transmission shaft to drive the brush head to rotate left and right to clean the teeth. The recommended way of use is to clean the teeth one by one, so the brush head is round.
Sonic toothbrush
The acoustic electric toothbrush is named after that the brush head is driven by a high-speed motor, and the vibration frequency of the approximate acoustic wave is perpendicular to the handle of the toothbrush to make a high-speed left-right swing.
The head of sonic toothbrush is a long strip. Generally, it can clean about 2 teeth at the same time, which is similar to the manual toothbrush we use everyday.
Rotary vs acoustic
According to the dental literature, rotary electric toothbrush can brush the contact surface of teeth more cleanly, and the plaque index of people who use rotary toothbrush is 1 / 3 lower than that of people who use sonic toothbrush.
According to relevant research, the average tooth wear of rotary electric toothbrush is 4-5 times greater than that of acoustic toothbrush. From this point of view, using sonic toothbrush is safer for our teeth, and the difference will be more obvious day by day.
Rotary toothbrush makes a lot of noise when working, which may make people who are sensitive to sound uncomfortable, while sonic toothbrush is quieter.
If the teeth are sensitive, have oral disease or would mind using noise, it is recommended to use sonic toothbrush.
2、 Cost of use
Brush head replacement
Electric toothbrush has the same life span as ordinary toothbrush, about 3 months, or replace according to the intelligent tips of toothbrush. For your health, please buy genuine brush head.
Charging mode of toothbrush
Pay attention to the type of rechargeable battery used by your toothbrush, which is nickel hydrogen or lithium ion. Although the current electric toothbrush indicates that it can be placed on the wireless charging base for a long time, the nickel hydrogen battery still has a memory effect that cannot be ignored. Please charge in the right way. Of course, the high-end lithium-ion battery doesn't matter. It can be charged as you use it.
Comparison with ordinary toothbrush
Compared with the manual toothbrush of tens of dollars, the electric toothbrush is indeed too expensive. The main reason for the price of the electric toothbrush is the body. But if the life is calculated, the price of electric toothbrush may not be so terrible.
We calculated according to 3 years' use of each electric toothbrush body and 3 months' use of brush head (1 year for official mark of filor f3308 brush head). In terms of the overall use cost of toothbrush, the daily use cost of high-end toothbrush is 1.88-1.9 yuan, the daily use cost of middle end toothbrush is 1-1.31 yuan, and the daily use cost of entry toothbrush is 0.54-0.93 yuan. The daily use cost of manual toothbrush is 0.44 yuan.
Of course, there are some limitations in this calculation, such as the service life of the fuselage. For example, some high-end electric toothbrushes with better technology may have a service life of more than 3 years, so the use cost will be lower, while the entry-level electric toothbrush is not so good in workmanship and parts, and it may not be able to reach 3 years in actual use, and the relative daily use cost will rise.
