How to choose an electric toothbrush? Just remember the four points
As an oral cleaning tool, electric toothbrushes are much stronger than manual toothbrushes in terms of cleaning effect and ease of use. But when choosing an electric toothbrush, we must pay attention to distinguish between good and bad. Now there are many categories of electric toothbrushes on the market, and the promotional slogans are even more dazzling, and it is easy to buy fake and shoddy products if you are not careful. How to choose an electric toothbrush? Here is a summary of the 4 points to pay attention to, let's find out together.
- Look at the motor of the electric toothbrush, preferably the magnetic levitation sonic motor. The reason why the electric toothbrush can vibrate and realize the freedom of the hands is mainly driven by the internal motor motor. The quality of the electric toothbrush motor directly determines the use effect of the electric toothbrush. At present, there are two main types of motors used in electric toothbrushes on the market: rotary type and sonic type. The rotary motor drives the gear through the rotation of the motor shaft, and then transmits the power to the brush head to rotate together, the friction between the machinery is relatively high, the noise will be very large, long-term use will damage the tooth enamel, and the tooth gap and other parts can not be cleaned in place.
According to the difference in working principle, acoustic type motors are divided into two types: ordinary eccentric motors and magnetic levitation sonic motors. Eccentric motor uses the centrifugal force of the eccentric wheel to drive the whole fuselage to vibrate together, this kind of motor cost is relatively low, the vibration effect is not easy to grasp, too weak electric toothbrush cleaning effect can not be guaranteed, too strong will damage the teeth, but also easy to numb. The magnetic levitation motor mainly uses the electromagnetic plus vibration device as the vibration source, and the magnetic field is formed after being energized, and the vibration device is suspended in the middle of the magnetic field to form a high-frequency vibration frequency, and finally conducts to the brush head through the transmission shaft. It can be cleaned deep into the gap between the teeth and is much less noisy when used.
- Look at the brush head of the electric toothbrush, preferably the brush head is smaller in size, and the bristles are nylon bristles. In addition to the motor, the brush head is a key part that directly touches the teeth, so the choice of brush head is also crucial. Choose a small brush head size for more flexible rotation in the mouth, and clean the gaps between the teeth and the inside of the mouth. Common bristles are nylon bristles, PBT bristles, polypropylene bristles and PET composite bristles. Nylon wire from the United States has excellent characteristics such as moderate soft and hard, wear resistance, and top rounding, suitable for most people, and the cleaning effect is better.
PBT bristles are pointed, characterized by good softness, non-absorbent, good resilience, suitable for people with sensitive mouths, but because the bristles are very soft, not suitable for long-term use, the cleaning effect will decrease. Polypropylene bristles are hard and inexpensive materials, which are used in most hotels, and usually pour after one or two brushes. PET composite bristles are a kind of nylon-like composite material, with poor resilience and average cleaning effect. In addition to this, bristle roundness is also critical. Roundness refers to the rounding of the top of the bristles, the untreated top is relatively hard, showing a sharp irregular shape, although invisible to the naked eye, but can be clearly seen under a microscope several times magnification. Easily scratch the gums and damage the teeth. Therefore, when choosing a toothbrush, the higher the roundness is generally chosen, the better.
- Look at the battery life of the electric toothbrush, the longer the battery life, the better. Electric toothbrushes generally have two types: charging and dry batteries, and it is recommended to use charging models without frequent battery changes. The use of electric toothbrushes, not only look at the cleaning ability, the battery life is also very important, just like mobile phones, the longer the use of a single charge, the better the battery performance, and the more convenient to use. Generally, the battery life of electric toothbrushes with relatively low prices is not very good, when we choose an electric toothbrush, we must carefully compare with the product description and choose a long battery life to buy and use.
- Look at the waterproof performance of the electric toothbrush. The higher the waterproofing of an electric toothbrush, the longer the lifespan. Now many electric toothbrushes on the market generally achieve IPX7 waterproof, which is equivalent to brushing teeth while bathing will not enter the water and cause damage to the electric toothbrush, which adds great convenience to life. Therefore, when buying an electric toothbrush, you must be optimistic, do not choose the waterproof level below IPX7.
The above 4 points are the main points of choosing an electric toothbrush, choosing an electric toothbrush that suits you is beneficial to oral health, including your own health.
