What is an electric toothbrush?

As a tool for efficient tooth cleaning, the electric toothbrush can produce automatic and rapid bristle vibration, oscillating in front and back or in a rotating manner (the head of the brush rotates alternately in clockwise and counterclockwise directions) to achieve the effect of tooth cleaning. The toothbrush is powered by a driving motor that vibrates at or below the speed of sound.

In plain English, the popular electric toothbrush is divided into two categories: rotary and acoustic.

1. Rotation:

The rotary electric toothbrush cleans teeth by rotating the bristles alternately. It is characterized by stiff bristles and noisy toothbrush operation.

2. Sound wave type:

    The frequency of acoustic electric toothbrush is about 22000-40000, and each brand is different. The high frequency vibration of the brush head can fully mix the toothpaste and water evenly and produce a large number of tiny bubbles in the mouth, which can clean the teeth by squeezing the bubbles.

Most people use a vibration frequency of 31,000 is enough, too high will damage the teeth and gums, beginners recommended to choose 28800-36000 this range.

Points to note when choosing an electric toothbrush:

1. electric toothbrush Brush bristle hardness:

Hard bristles: Hard bristles have strong cleaning ability and need more pressure to go deep into the dead corners. Make sure you have strong gums to withstand it. People who drink coffee and smoke and have healthy gums can choose hard bristles if they need to whiten their teeth.

Soft bristles: Soft bristles are not a threat to the gums, but can massage the gums. Under normal circumstances, I recommend you choose soft bristles.

Pointed bristles: pointed very fine soft hair is the most easy to penetrate into all kinds of gaps, but the conduction of vibration energy is also weak, suitable for people with fragile gums.

2. electric toothbrush brush head material

Brush head material can be divided into silica gel brush head and plastic brush head. The silicone brush head is softer than the plastic one and more tooth friendly, reducing the amount of damage caused when the brush vibrates against the teeth.

3. electric toothbrush brush head size

Small brush heads are more flexible and easy to brush the corners of the back teeth, but with fewer bristles, the efficiency of brushing is too low.

Bigger brush head brushing area is larger, but the tooth corner is difficult to brush, easy to leave a dead corner.In the brush head can just make up for their deficiencies, brushing efficiency is high, brushing contact surface is relatively large. planting rate

Low price electric toothbrushes generally have low bristling rate, poor bristle quality, low rounding rate, and frequent use will damage teeth and gums.Hundreds of dollars to hundreds of dollars of electric toothbrush hair planting rate is very high, good quality, grinding round rate is good, so can not be greedy for small gains suffer big losses!

5. electric toothbrush grinding rate

Rounding can be said to be the top priority of the whole toothbrush. After all, whether the bristles are good or bad, whether they are round and smooth, or whether they are rough and molar, all need to contact the mouth directly. The products that have been used for several years must be chosen correctly.
