How does an electric toothbrush brush your teeth? Do I need to charge the new electric toothbrush?

Nowadays, electric toothbrushes are quite common. Many people choose electric toothbrushes because they can brush teeth more cleanly. So how do electric toothbrushes brush teeth? Do you need to charge the new electric toothbrushes?

How to brush teeth with an electric toothbrush

First, follow the installation method in the manual of the electric toothbrush and forcefully put the brush head onto the toothbrush shaft. Because electric toothbrushes have a high vibration frequency, choose toothpaste with finer particles and softer properties to avoid excessive friction on the teeth and damage to the gums. Don't use too much toothpaste when squeezing it. After squeezing, put the brush head into your mouth first, and then turn on the toothbrush button to prevent the toothpaste from being vibrated. Brush each area of ​​the teeth for about 30 seconds. When brushing the outer side of the teeth, open your mouth a little wider and hold the toothbrush handle horizontally. Move the brush head slowly along the gum line and stay on each tooth for two to three seconds. When cleaning the chewing surface of the teeth, the teeth inside are prone to accumulate bacteria, so stay for a few more seconds. After brushing, turn off the power and rinse your mouth with clean water. Rinse the toothbrush and put it in a cool and dry place.

Do I need to charge the new electric toothbrush?

When you buy an electric toothbrush, you don't need to charge it if it has power. If it is low on power, you need to charge it before use. Manufacturers charge toothbrushes before leaving the factory. Generally speaking, new toothbrushes have power, but generally this power can only support a short period of use. There is no need to charge for 12 hours for the first time. Since most electronic toothbrush products currently use nickel-metal hydride batteries, the memory effect of this type of battery is minimal, so it can be charged as you use it. In addition, since the charging voltage of this battery is low, the charging time is relatively long. The specific time is determined by the battery capacity of the electric toothbrush. Generally, there will be a prompt after it is fully charged. After the charging completion prompt appears, you can unplug the toothbrush.

The principle of electric toothbrush

In principle, there are two types of electric toothbrushes: rotary and vibrating. The principle of rotary toothbrushes is simple, that is, the electric motor drives the circular brush head to rotate, which enhances the friction effect while performing ordinary brushing actions. Rotary toothbrushes have strong power, clean the tooth surface very cleanly, and the cleaning of the gaps between teeth is relatively weak, but they cause great wear on the teeth and are not recommended for long-term use. Vibrating toothbrushes are more complicated and more expensive. There is an electrically driven vibration motor inside the vibrating toothbrush, which allows the brush head to produce high-frequency swings perpendicular to the direction of the brush handle, but the swing amplitude is very small, generally about 5 mm up and down, and the largest swing amplitude in the industry is 6 mm.

Are electric toothbrushes good?

Yes, it is good, because it is difficult to completely remove dental plaque with a basic toothbrush, and the method of brushing teeth in daily life is incorrect, so the cleaning effect of brushing teeth is not fully exerted. Electric toothbrushes can remove 38% more dental plaque than basic toothbrushes. Electric toothbrushes can more thoroughly remove sub-organisms, reduce gingivitis, bleeding gums, etc.
