With the improvement of technology, electric toothbrush can be divided into many kinds. Generally, it cleans teeth by vibration and rotation, and some high-end ultrasonic instruments are equipped with impulse and water spraying to clean teeth. The ordinary electric toothbrush which sells for tens of yuan on the market is only simple vibration and rotation. Its frequency and intensity are very large and fixed. Ultrasound toothbrushes generally do not harm teeth and gums, and can clean teeth very clean, but very expensive.
Electric toothbrushes are more suitable for people with handicap.
They can’t force their teeth with toothbrushes. Therefore, electric toothbrushes are more suitable for such people. For ordinary people, electric toothbrushes are not recommended.
The brush of electric toothbrush is rotated, so it needs to stay on each tooth for a period of time, taking into account three teeth, in order to achieve the purpose of cleaning teeth, which is time-consuming. Therefore, the use of electric toothbrushes requires sufficient patience in order to truly clean teeth. If you just put the toothbrush in your mouth and move up and down synchronously, you can’t completely clean the pits and fissures of teeth, gums and crevices, and other special parts of the bacteria, it will also cause dental disease. Correct use of electric toothbrushes does have the effect of removing plaque, preventing dental caries and periodontitis, but these functions are the same as ordinary toothbrushes. Electric toothbrushes only change the way people brush their teeth, and can not completely replace the role of cleaning teeth. However, when many people brush their teeth manually, due to improper ways and excessive brushing force, it is easy to cause unnecessary damage to teeth and gums. Electric toothbrush can reduce this damage and massage the gums. But if the electric toothbrush is not used properly, it will damage the teeth. Usually ordinary toothbrushes are used to brush up and down actively, that is, vertical brush. The vibration frequency and force of the electric toothbrush are relatively fixed. When rotated, it is similar to the cross brush on the surface of the teeth. It may cause some wear and tear on the teeth, and serious periodontitis may occur. If the teeth themselves are not good, such as gingivitis, periodontitis, it is best not to choose electric toothbrush.
The frequency and intensity of electric toothbrush are fixed, because children can not grasp the appropriate method of use for a while, easy to damage the tender gingiva, make the gingiva appear red and swollen symptoms, but also make the teeth suffer severe wear and tear, serious cases can also cause periodontitis, resulting in tooth loss. Children’s use of electric toothbrushes has many drawbacks, should be cautious!
There are also electric toothbrushes thousands or even tens of thousands of times per minute of vibration frequency, may produce an electric wave, will have a negative impact on the human body, it is difficult to say.
Cautions in the Use of Electric Toothbrush
When used for the first few days, it should be charged for 24 hours.
Install the brush head: Align the stick protruding from the brush head to the groove of the brush handle, slide the brush head into the brush handle; rotate the brush head nut clockwise until it is tightly fastened to the brush handle.
Although electric toothbrush has good cleaning effect, it is better not to use it for preschool children before 7 years old. Children before 7 years old are in the critical period of tooth growth and tooth replacement, and their teeth and periodontal tissues are relatively young. Compared with ordinary toothbrushes, electric toothbrushes with fixed vibration frequency and force, if children use improperly, such as excessive force, or a part of the use of too long, may cause damage to periodontal tissue. It is best to consult a professional dentist for specific matters.
