The electric toothbrush was invented by a Swiss doctor, with its origins dating back to 1959. However, for nearly 70 years, electric toothbrushes of that era did not differ significantly from ordinary toothbrushes.Modern electric toothbrushes primarily consist of a rechargeable battery, a miniature DC motor, a battery compartment, a brush head, a metal guard, and a sleeve. In general, electric toothbrushes are classified into two types: mechanical rotation and sonic vibration.
Visit and Manufacturing Context
Mechanical rotary electric toothbrushes use a motor to drive the brush head in a left-to-right circular motion, similar to manual brushing, but at a faster speed than what the average consumer achieves when brushing by hand. The brush head and bristles clean the teeth and mouth more effectively through the friction generated by rapid rotation.However, compared to manual brushing, the range of motion remains quite limited—approximately 5 millimeters up and down—and the speed typically ranges from 7,000 to 9,000.
Acoustic-vibration electric toothbrushes are driven by a high-speed motor, but their vibration is gentle and frequent, with a smaller amplitude than mechanical toothbrushes. The vibration frequency of products currently on the market generally reaches around 20,000 times per minute, and some ultrasonic electric toothbrushes can even reach 60,000 times per minute.
Production, Quality, and R&D
It is worth noting that “sonic” electric toothbrushes do not actually use “sound waves” to brush teeth; rather, they utilize bristles that move rapidly at a frequency similar to that of sound waves to achieve a level of cleaning speed and effectiveness beyond that of traditional manual toothbrushes.Fundamentally, using an electric toothbrush can effectively prevent the damage to gums and periodontal tissues caused by ordinary toothbrushes.
Electric toothbrushes are primarily marketed for their precision and sophistication. For example, when an electric toothbrush vibrates at over 30,000 times per minute, it generates a large number of tiny bubbles in the mixture of toothpaste and water inside the user’s mouth; the pressure created by these bursting bubbles penetrates deep into the teeth to remove plaque—something that is difficult to achieve with a regular toothbrush.
Partnership Considerations
In addition, manual toothbrushes present several practical issues, such as variations in bristle quality and size, differences in how long consumers use them, and variations in brushing intensity. Consequently, manufacturers of electric toothbrushes claim that electric toothbrushes are easier to use than manual ones.
