General toothbrush VS electric toothbrush is obviously superior to general toothbrush in price. The price of electric toothbrush is generally 20 times higher than that of ordinary toothbrush10, and the electric toothbrush head of this toothbrush needs to be replaced on time. As for Xiao Yujun's knowledge, the prices of all kinds of electric toothbrush heads sold in the market at this stage are not cost-effective, and a single one is only 50 ~ 80 yuan. After investing an expensive price, everyone is more concerned about which toothbrush is cleaner.
In fact, the result is likely to make you sad. After comparing more than 30 scientific research graduation papers, we found that there is no obvious difference between manual brushing and electric brushing, and some bad electric toothbrushes may also damage teeth and gums.
In other words, the electric toothbrush can only deal with the problem of lazy people brushing their teeth, but it won't make your teeth more and more tidy. Even if you only use an ordinary toothbrush, brushing your teeth well can make your teeth "white and tender".
How to choose an electric toothbrush that suits you? If you are just lazy when brushing your teeth, buying an electric toothbrush is naturally a very good choice. When choosing a toothbrush, you can refer to the following three suggestions: Specifications: Pay attention to the specifications when choosing a toothbrush to ensure that the toothbrush head can fully contact and clean every surface of the teeth. For most adults, a toothbrush head with a length of 2.5 cm and a width of 1.25 cm is very suitable.
Although theoretically, the larger the toothbrush head, the larger the contact area, but the area inside the mouth is limited. The toothbrush is very big, but it is inconvenient to walk in your mouth, leaving a lot of messy things, especially molars.
Toothbrush bristles: What really touches the teeth on the toothbrush is toothbrush bristles. Toothbrush bristles can be roughly divided into soft, medium and hard according to the degree of hardness. Most people are suitable for comfortable round soft toothbrush. If you use a toothbrush with medium or thick bristles, the gear position is too high when brushing, which may indeed damage the interior of the mouth, the surface of teeth, gums, and even maintain the enamel of teeth.
Toothbrush stick: When buying an electric toothbrush, it is recommended that you also choose a standard and efficient product, otherwise once the toothbrush has problems such as power failure, it will easily hurt your lips. In addition, the toothbrush stick you buy must be 18 ~ 20 cm long, so that it can be easily manipulated in your hand.
