Is there a reliable and practical electric toothbrush?

Isn't there an electric toothbrush in the world with soft bristles, strong cleaning power, and a reliable, practical brush that doesn't damage gum enamel? YES!!! There are! !!!!

Two months ago, I took $five thousand budget (company suddenly sent global bonus, IQ as I continue to pay taxes with teeth to the light of funding, murdered paranoia I don't believe in other people's evaluation can only yourself to fit), to buy back a treasure to pin 30 electric toothbrush before last month, play a pseudo chemistry students one of the few experimental spirit, As well as once to a "meal chewing two grains" well-known brand to write oral science content more than 200 dental paper reading reserve, comparative experimental evaluation, finally found. Unbrushed electric toothbrush surfaces tend to have sharp, irregular shapes, and even colored bristles turn white, like a broken pencil lead cross section. Every time you brush your teeth, the brush with low round rate will directly damage the tooth enamel and gums. This is also the reason why many people will bleed gums when they brush their teeth with the electric toothbrush provided by the hotel Express. It is not because of acclimation, fire, and too much effort to brush their teeth.

The hardness of the bristles is different from each other, but it needs to be considered that under the vibration of tens of thousands of times per minute of electric toothbrush, even the soft bristles of electric toothbrush will bring the tactile sensation of stiff oral hair, and the violence will not only produce miracles, but also cause gingival bleeding. Imagine, a wind is very weak very weak electric fan, fan blade touched a chopstick will have what consequence? The fan will stop. An electric toothbrush with a cheap motor and a poorly designed vibration frequency can have the same effect on the upper teeth as a manual toothbrush. Promise me you won't buy them, and take care of your mouth and your wallet! Briefly introduce the working principle of electric toothbrush. There are two kinds of electric toothbrushes on the market at present, which are acoustic wave type and rotary type respectively. The latter is the patent of , so other brands are basically acoustic wave type. Working principle of rotary electric toothbrush: The motor drives the brush head to rotate, and the cleaning effect can be achieved by the friction between the bristles and the teeth during rotation. The supporting bristles are usually relatively hard, which can clean the tooth surface with great cleaning force and easily cause tooth wear, but the cleaning between teeth is weak. Working principle of the sound wave type electric toothbrush: motor drive brush head high frequency vibration, and high frequency drive brush do small oscillation amplitude, more than 30000 times/min vibrations frequency of electric toothbrushes are strong cleaning effect, can let the toothpaste and water mixture to produce a large number of tiny air bubbles, the bubbles burst pressure can deeply realize the deep clean teeth and cause no harm.
