Flower Dad said:
Electric toothbrush, which can efficiently clean tartar, has become an "essential artifact" for brushing teeth with a baby, saving time and effort.
Children's electric toothbrushes, the official has no special age recommendations, but manufacturers generally recommend 3 years old and older.
In addition, according to official organizations such as the American Society of Pediatric Dentistry and the American Dental Association, parents must assist and supervise their children's brushing before the age of 7.

Therefore, Hua Dad recommends that parents need to be accompanied by children under 7 years old when brushing their teeth with an electric toothbrush.
So, how should children's electric toothbrushes be chosen? This issue of Flower Dad will come to give you a review.

At present, there are two main types of electric toothbrushes on the market, namely mechanical rotary type and sonic vibration type.
Mechanical rotary electric toothbrush, the use of motor-driven brush head to do left and right two-way circular movement, modeled on manual brushing, but faster than the general manual brushing speed, brush head and bristles in the rapid rotation friction to achieve the role of cleaning teeth and mouth.
Sonic vibration electric toothbrush, the use of high-speed operation of the motor to drive the high-speed vibration of the toothbrush head, but this vibration method is slight and frequent, compared to the mechanical amplitude is smaller.
The intuitive feeling of using the two toothbrushes is that the noise of the sonic vibration electric toothbrush will be smaller.
Which of these two ways is better to brush your teeth? At present, the scientific community has no definite conclusion.
But surely: whether it's mechanical rotation or sound vibration, it's cleaner than manual brushing!
Hua Dad believes that electric toothbrushes are more fun and can increase children's interest in brushing their teeth.

In 2019, when Hua Dad tested children's electric toothbrushes, the mechanical rotary model was slightly superior. After 3 years, Hua Dad improved the test method according to the new standard to see who could win.
There are many different brands of sonic vibratory toothbrushes, but mechanical rotary toothbrushes, well-known and hot-selling brands are only Ou LB.
Hua Dad purchased 1 mechanical rotary electric toothbrush and 6 sonic vibration electric toothbrushes with high sales on the e-commerce platform.
Note: Hua Dad's 19-year recommended Euro LB has been removed from the shelves, and Hua Dad has chosen the hot-selling model of the same brand for testing.
Bristle flatness
The bristles of Bai E and Fei L Pu are burrs and sharp
In 19 years, when Hua Dad evaluated children's electric toothbrushes, there was no national standard that could be referred to, and only GB 30002-2013 "Children's Toothbrush" (not applicable to electric toothbrushes) and GB 30003-2013 "Sharpened Silk Toothbrush".
In August 2021, the mainland issued GB/T 40362-2021 "General Requirements and Testing Methods for Electric Toothbrushes", which was implemented in March this year. However, the requirements for bristles are not as detailed as described in the above two standards.
Therefore, Hua Dad believes that the judgment of bristles can refer to the above 2 ordinary toothbrush standards:
The top of the ordinary bristle should be round enough, no burrs, and the sharpened bristles should be neat and straight, without too many forks, so that the wear on the teeth and gums is relatively small, and it is more comfortable to brush.

Cut from: GB 30003-2013 《Sharpened Toothbrush》
Hua Dad used a microscope to magnify 100 times to view the bristle status of 7 electric toothbrushes, as shown in the following figure:
Among them, Bai E and Fei L Pu have more obvious burrs and sharpness;
Shu K's bristles are designed as a long and a short two-layer, the longer one is the sharpened filament, that is, the top is a pointed cone shape, which can be seen under the microscope, and the tip has some forks, which are not flat enough;
The shorter ones are ordinary bristles, which are more rounded.
On the left are short ordinary bristles and on the right are long sharpened hairs
The rest of the electric toothbrush bristles are rounded, burrs-free, and more comfortable to brush.
k*ta has the best cleaning ability
The egg shell is similar to the outermost enamel of the tooth, and the composition is similar. Moreover, the surface of the egg shell is uneven, which is convenient for judging the cleaning effect of different toothbrushes. So Hua Dad used egg shells instead of teeth to test the cleaning ability of each toothbrush.
Test method: Apply pigment to the eggshell to simulate stain residue, squeeze the same brand, soybean-sized toothpaste on the electric toothbrush, brush back and forth with the same force for 30 seconds, and use a magnifying glass to observe the stain residue on the flat surface of the eggshell, bumps and bumps.
brief summary:
1, k *ta cleaning ability is the best.
Pigment can be washed off both on flat surfaces and bumps.
2, byE, Ou LB cleaning ability is good.
There is a little residue of the surface pigment, and the bumps can be cleaned.
3. The cleaning ability of Shu K, Fei L Pu, C*mbo, U*m*le is poor.
There is obvious pigment on the surface and in the bumps, and the cleaning ability is poor.
noises
The toothbrush is too noisy when running, which may make children feel resistant.
Referring to GB/T 40362-2021 "General Requirements and Detection Methods for Electric Toothbrushes" (to be implemented, hereinafter referred to as "Detection Methods"), the noise of electric toothbrushes should be <72dB(A).
Truncated from GB/T 40362-2021 "General Requirements and Detection Methods for Electric Toothbrushes" (to be implemented soon)
Hua Dad tested the noise of 7 electric toothbrushes when the office was quiet, and the results were as follows:
Note: The ambient noise in Hua Dad's office is 36 decibels, and there is only a slight sound of tapping on the keyboard.
1, Shu K, Fei L Pu, k * ta noise is small.
2, The noise of Euro LB is the largest.
The noise of the mechanical rotation model would have been greater than the vibration of the sound wave, and in the 19-year evaluation, the European LB was also the loudest, but at that time, its cleaning ability was the best, and The flower father took it as a recommended model.
Brush head size
Children's oral space is small, and the size of the brush head should be moderate.
Referring to the "Detection Method", the bristle height, hair length and width of children's electric toothbrushes should meet the requirements.
We measured the bristles of 7 electric toothbrushes one by one, and the results were as follows:
Summary: The size of the 7 children's electric toothbrushes all meet the requirements of the reference standard, which is suitable for babies to brush their teeth.
Whether there is a non-slip, protective design
Children love to bite their teeth and brush heads, and brush heads made of plastic resin and other materials are hard and easy to teeth. Therefore, the silicone protection on the brush head is very important.
If the brush handle is not anti-slip, children are easy to "slip".
C*mbo, Philips, k*ta, U*m*le brush head, brush handle has "silicone protection".
There is no "silicone protection" on the brush heads and handles of Shu K, Ou LB, and Bai E.
Most of the functions of children's electric toothbrushes on the market are similar, such as area change prompts, 2min timing shutdown, multiple gears, and waterproofness. Flower Dad lists them one by one for everyone's reference.
The functionality of the 7 children's electric toothbrushes is shown in the following table:
Note: IPX7 is "can be immersed in water for a short time"
1, comfortable K, k *ta charging port is not protected, exposed, pay attention to the charging port dry when charging.
U*m*le is a Type-C charging, with charging port protection, not easy to enter the water situation.
Ou LB, C*mbo, Fei L Pu, Bai E for inductive charging, do not have to be afraid of water when charging.
2, Ou LB does not have a 2-minute timing shutdown function, when brushing teeth, parents should help children control the brushing time.
3. Although there is no standard waterproof model for European LB, the detail page is marked as a waterproof fuselage, so don't worry about waterproofing.
179 yuan
Model: K2
Advantages: good bristles; low noise; toothbrush size can meet the standard requirements; the cleaning ability is the best; there is a non-slip, protective design; 2 minutes timed shutdown.
Disadvantages: The charging port does not have a waterproof design.
1. Precautions for purchasing children's toothbrushes.
The brush head should not be too large, it will bump the teeth; the bristles should not be too hard, it will scratch the gums and the inner wall of the mouth; the brush handle should be non-slip and easy to grasp, which is convenient for children to grasp.
2, caries is not only because of eating sugar.
The main cause of caries is dental plaque, even if the child is not allowed to eat sugar, eating other foods is not cleaned up in time, it will form plaque attached to the surface of the tooth, so it should be cleaned up in time.
