How does people buy an electric toothbrush?

In my opinion, electric toothbrush is not harmful to teeth, although some girls may find the vibration sound terrible, but in fact it is only high frequency vibration, you can imagine your hand brush 10 times faster than the ghost-animal effect, the difference is that toothbrushes electric vibrates by itself, and you need the invisible hand.That why the little sister above brushing teeth instead of brushing teeth out of the problem?The purpose of brushing our teeth is to remove the plaque. Why don't we just rinse our teeth or use a tooth punch every day, but use an sonic toothbrush  to brush our teeth? Because the plaque needs to be removed by physical and mechanical action, so don't think you hurt your teeth and don't brush your teeth seriously.Similarly, when brushing your gums bleed, you will feel that your gums can not stand brushing too much, and you dare not brush them. In fact, the bleeding of the gums is often because of the sub-health of the oral cavity. The gums are in a very fragile state, so it is easy to bleed when the bristles are stimulated.So, electric toothbrush is a must!So how to not hurt your teeth, you need to brush your teeth properly.

When purchasing, try to purchase electric toothbrushes with complete label information through formal channels. Avoid buying "three No" products without product name information, brand model and warning.The appropriate electric toothbrush should be selected according to the user's age and dental condition.Children should choose a child electric tooth brush.If the user's teeth are more sensitive, the brush head with soft bristles can be selected to reduce damage to teeth and gums.Try to choose sonic electric toothbrush that can provide a variety of working modes. In the initial use, it is not suitable to use the strong working mode, but to start using the soft working mode, so that the teeth have a period of adaptation.The size of the user's mouth should be fully considered, and the selected brush head should not be too large.If the brush head is too large, it will be difficult to move around the mouth and fully clean the different parts of the teeth.Pay attention to the functions of the electric toothbrush, such as intelligent time reminder function, pressure sensing function, low power 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 every 30 seconds to remind the user to change the location of brushing, and ensure that the user brushing time is not less than 2 minutes.Some users have trouble controlling the pressure the electric toothbrush exerts on their teeth.Too much pressure can cause the bristles to wear down your teeth and damage your gums.Therefore, some electric toothbrushes have added a pressure sensing function, which automatically reduces the vibration frequency of the toothbrush when detecting excessive pressure on the teeth, reducing the damage to the teeth.

Because the vibration frequency of kids electric toothbrush is too fast, sometimes gently leaning on the gums, will feel to a burst of sour and soft.Discomfort is only one thing. There is no doubt that gums are also affected.The way to prevent this is to make the top of the electronic toothbrush bristles round, rather than letting the bristles stick to the gums immediately.Buy a soft toothbrush, buy accessories electric toothbrush manufacturer head, all need to pay attention to the arc of the toothbrush.What say is in among them how many accounts for the tooth brush hair, the top of the head is round.It is proposed to buy an sonic toothbrush manufacturer head with no less than 70% arc.
