Is sonic toothbrush really "ultrasonic cleaning"?

Toothbrush is just a tool, can not rely on too much, attitude and method is the most important. An ordinary hand toothbrush can also achieve excellent results. Electric toothbrushes simply lower the bar for brushing your teeth, making it easier and easier. The effect varies from person to person. It's not that a weak electric toothbrush is useless. Daily care of better teeth, the surface is smooth, weak toothbrush can also clean. With plaque and stones attached to the tooth, the surface is similar to the paste model, and the cleaning effect of the toothbrush will be greatly reduced. The structure of the brush head has a great influence on the cleaning effect. The fine and soft brush hair is easy to penetrate the gingival crevice and between teeth, while the hard and coarse brush head is difficult to do. The forced brushing seam will also damage the fragile gums and even damage the enamel.

Q: Is sonic toothbrush really "ultrasonic cleaning"? Which is better than the mechanical one?

There are two main schools of electric toothbrushes on the market. Mechanical rotation: the use of motor rotation to drive the swing arm, simulated manual brushing, but faster and more violent. The brush head and bristles rotate or reciprocate to achieve the cleaning effect by rubbing. Sound wave vibration type: rely on the high-speed movement of the motor to produce vibration, transfer to the bristles, produce slight and fast movement, through the shock to achieve the effect of cleaning.

Many toothbrushes are referred to as "ultrasonic", which is actually an exaggerated statement, and is not really using ultrasonic brushing. These toothbrushes vibrate 15,000 to 70,000 times per minute to create a certain amount of cavitation at the bristles' edges, causing water and air to move along with the mixture at high speed, which can have a stronger scouring effect on the tooth surface, stripping away food debris and plaque. Ultrasound, on the other hand, has a frequency of more than 120,000 times per minute, which is a long way off. Which is better, machinery or sound wave? Personally, I prefer a sonic toothbrush. Although the mechanical cleaning of tooth surfaces is very efficient, the sonic toothbrush is easier to clean into areas such as the gingival crevicular and has less physical wear on teeth.

There are probably only two functions that really play a role: intelligent timing, which ensures brushing time; The second is pressure sensing, to prevent excessive force injury teeth.

In the gear, the difference is not so obvious. May be for people with sensitive teeth or poor periodontal conditions, ordinary cleaning mode is too strong, sensitive care and gum massage will be much better, but the cleaning effect is not so good.
