Electric toothbrush reviews

This is one of the biggest concerns for anyone looking to buy an electric toothbrush. If you search for relevant questions, you will find many professional answers. For people like me with suspicious heart, even when I see data and written reports, I feel more or less uneasy (in fact, I do) and have a knot in my heart. So, I'm going to test it out for myself and see if an electric toothbrush really works better than a manual one. Toothbrush is just a tool, not to rely on too much, attitude and method is the most important. Ordinary manual toothbrushes can also achieve excellent results. Electric toothbrushes just lower the bar for brushing your teeth, making it easier and easier, and the results vary from person to person. It's not that weak electric toothbrushes are useless. Good daily care teeth, smooth surface, weak toothbrush can also clean. If the surface of a tooth is similar to that of a paste model, the cleaning effect of a toothbrush will be greatly reduced. The structure of the brush head has a great influence on the cleaning effect. Only thin and soft bristles are easy to penetrate into the gingival sulci and crevice, while the rough brush head is difficult to do. Forced brushing will damage the fragile gums and even the enamel.

There are two main types of electric toothbrush on the market. Mechanical rotation: Using the rotation of the motor to drive the swing arm, mimicking manual brushing, but faster and more violent (it can be called a simple polishing machine!) . Electric toothbrush head and bristles rotate or reciprocate to achieve cleaning effect through friction. Acoustic vibration: vibration is generated by the high speed movement of the motor, which is transmitted to the bristles to produce a slight and fast movement and achieve the cleaning effect through vibration. Many toothbrushes are labeled as "ultrasonic", which is an exaggerated statement and is not really using ultrasonic to brush your teeth. These electric toothbrush vibrate 15,000-70,000 times per minute to produce a certain amount of cavitation at the bristles' edges, causing water and air to move with the mixture at high speed, which has a stronger scouring effect on the surface of teeth, stripping food particles and plaque. The frequency of ultrasound is more than 120,000 beats per minute, which is a long way off. Which is better, machinery or sound? I personally prefer sonic electric toothbrush, which are more efficient at cleaning the surface of teeth mechanically, but are easier to clean into areas such as the gingival crevicular and have less physical wear on teeth. The difference is due to energy loss, which means the vibration can't be transmitted 100% of the time. The transmission efficiency depends on the motor and drive shaft of the toothbrush. Some low-end sonic electric toothbrush use special high-speed motors to drive eccentric wheels that vibrate; Higher-end products use linear vibrators, or "maglev motors," which are used in the Tapic Engine. The biggest difference between an electric toothbrush and a regular one is that one requires electricity and the other requires only human power, so battery life is a problem. And for those who travel a lot, portability is especially important.
