Is an electric toothbrush really cleaner than a manual toothbrush?This is one of the biggest concerns for anyone looking to buy an electric toothbrush.But for people like me who have doubts, just seeing data and written reports, or more or less a little uneasy
So I'm going to put it to the test, to see if, in my truest experience, an electric toothbrush really works better than a manual toothbrush.
We ransacked nine electric toothbrushes from the harem advisory group around us and had a full-scale PK.
We have come to the following conclusions: electric toothbrush is just a tool, do not rely on too much, attitude and method are 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, and 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 electric 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.Electric toothbrush head structure has a great impact on the cleaning effect, fine and soft brush hair is easy to penetrate the gingival crevice and teeth, hard brush head is difficult to do, forced brushing seam will also damage the fragile gums, and even damage the enamel.
Is sonic electric toothbrush really "ultrasonic cleaning"?Which is better than the mechanical one?
Electric toothbrushes on the market fall into two main genres.
Mechanical rotary electric toothbrush: using the rotation of the motor to drive the swing arm, simulated manual brushing, but faster and more violent (called a simple polishing machine!).The brush head and bristles rotate or reciprocate to achieve a clean effect by rubbing.
Sound wave vibration type electric toothbrush: rely on the high-speed movement of the motor to produce vibration, transfer to the bristles, produce a slight and fast movement, through the shock to achieve the effect of cleaning.
Many electric toothbrushes are referred to as "ultrasonic", which is an exaggerated statement, and is not really using ultrasonic brushing.
These electric toothbrushes vibrate 15,000-70,000 times per minute to create a certain amount of cavitation at the edge of the bristles, causing water and air to move together with the mixture at high speed, which has a stronger scouring effect on the tooth surface, stripping away food debris and dental plaque.Ultrasound, on the other hand, has a frequency of more than 120,000 times per minute, which is a long way off.
As for mechanical and acoustic electric toothbrush which good after all?Personally, I prefer a sonic electric toothbrush. Although the mechanical cleaning of tooth surfaces is very efficient, the sonic electric toothbrush can be easily cleaned to areas such as the gingival crevicular, and there is less physical wear on the teeth.
Are all acoustic electric toothbrushes the same?
This difference is due to energy loss, vibration can not be 100% transfer, and the transmission efficiency depends on the electric toothbrush motor and shaft.Some low-end acoustic electric toothbrushes use a special high-speed motor to drive an eccentric wheel to produce vibrations.The more advanced products use linear vibrators, or "maglev motors."
