Introduction:If you search on Pinduoduo, you’ll find a wide variety of inexpensive electric toothbrushes, ranging from a few yuan to several dozen yuan. Many customers ask us, “Can a 9.9-yuan electric toothbrush actually work? Is it a fake?”
Here, I’d like to say: Electric toothbrushes that cost just a few yuan—they work, but they aren’t very effective. It’s true that they work, but they don’t really do the job.

Now, let’s follow Aiwejay as we take a look at the differences between electric toothbrushes that cost a few dozen yuan and those that cost a few hundred yuan in terms of hardware, cleaning performance, and accessories.
I. Differences in Hardware Between Low-Cost and Brand-Name Electric Toothbrushes
Brush Head
The brush head is the most important part of a toothbrush, because it is the brush head that vibrates and rubs against the teeth to remove impurities such as plaque and tartar, thereby cleaning the teeth.
Criteria for Evaluating the Quality of a Toothbrush Head: Bristle Material, Bristle Density, and Rounding Rate
Material:
Toothbrush bristles are primarily made of either natural boar bristles or nylon fibers; currently, all toothbrushes on the market use nylon bristles. Mid- to high-end electric toothbrushes generally use bristles manufactured by DuPont in the United States.
Hair Transplant Density:
A high bristle density in the brush head means more bristles, which increases the surface area in contact with the teeth and naturally leads to better cleaning results.
Roundness Ratio:
The rounding rate has a direct impact on gum protection. The surfaces of bristles that have not undergone rounding treatment are mostly irregular in shape and relatively sharp. In contrast, the surfaces of bristles that have undergone rounding treatment are smoother and more rounded. Using an electric toothbrush with a rounding rate that does not meet standards can damage the soft tissues in our mouths, cause damage to tooth surfaces, and fail to achieve effective cleaning results.
Battery
Currently, the most common rechargeable batteries used in electric toothbrushes on the market are nickel-cadmium, nickel-metal hydride, and lithium batteries.
In terms of performance: Lithium-ion electric toothbrushes > NiMH electric toothbrushes > Ni-Cd electric toothbrushes
The more high-end an electric toothbrush is, the more advanced its battery is, and the longer its usage cycle and lifespan will be.
II. Comparison of Cleaning Modes for Electric Toothbrushes
Generally speaking, electric toothbrushes come with one or more cleaning modes. Mid- to high-end electric toothbrushes, in addition to basic cleaning modes, also offer modes such as whitening, polishing, gum care, and sensitivity care. The rotation pattern and speed of the brush head vary slightly depending on the mode.
III. Differences in Features and Accessories
1. Timer Function
Entry-level electric toothbrushes have very basic features; some don’t even have a 2-minute brushing timer.
Mid- to high-end electric toothbrushes not only feature a 2-minute brushing timer, but also include 30-second zone-specific reminders, charging progress alerts, and pressure warnings.
2. Safety
Most electric toothbrushes have an IPX5 waterproof rating, which means they can be rinsed under water. Generally, the more expensive the electric toothbrush, the higher its waterproof rating. Basically, electric toothbrushes priced at over 100 yuan have an IPX7 rating or higher, meaning they can not only be rinsed but also withstand immersion without significant damage.
3. Accessories
Generally speaking, entry-level electric toothbrushes don’t come with many accessories, while mid- to high-end models include items such as travel chargers, travel storage cases, and toothbrush storage cases, making them easier to carry, use, and store in a variety of situations.
By comparing these dimensions, we can see that in Electric Toothbrush In this category, there are indeed significant differences between products in different price ranges, and these differences directly affect the brushing experience.
All in all, the money you spend on an electric toothbrush is well worth it—they’re sure to meet your needs at every level. So, we don’t recommend buying electric toothbrushes that cost just a few yuan.
