Electric toothbrushes are divided into two main categories based on their operating principles, one of which is represented by Philips Sonic Electric Toothbrush ... one of which is the rotating electric toothbrush, as exemplified by Oral-B.Which of these two types of electric toothbrushes cleans better? Which one provides better cleaning results?
1. Vibration Modes of Rotating and Sonic Electric Toothbrushes
Rotary (Mechanical Motor): Major brands include Oral-B, among others. The principle behind rotary toothbrushes is simple: a motor drives a circular brush head to rotate, enhancing friction while performing standard brushing motions. Rotary toothbrushes are noisy and clean the tooth surfaces very thoroughly, but they are less effective at cleaning between teeth. However, they cause significant tooth wear and are not recommended for long-term use.
Vibration-type (sonic motor): A prime example is Philips, along with Xiaomi, Susi, and others. Vibrating toothbrushes contain an electrically powered vibration motor that causes the brush head to oscillate at a high frequency perpendicular to the handle. However, the amplitude of this oscillation is very small—typically around 5 millimeters up and down—with the industry’s maximum amplitude being 6 millimeters.
When brushing your teeth, the high-frequency oscillating brush head efficiently cleans your teeth, while the vibrations—exceeding 30,000 times per minute—create a large number of tiny bubbles in the mixture of toothpaste and water in your mouth. The pressure generated when these bubbles burst helps clean debris deep between your teeth.
2. Which one cleans better?
Let’s take a look at the vibration frequency. Of course, higher isn’t always better—once a certain level is reached, the cleaning effectiveness stops improving. On the contrary, the higher the frequency, the less comfortable it actually becomes; it feels like holding a power drill.
Currently, the standard vibration frequency on the market is 31,000 times per minute. If the frequency is lower than this, cleaning effectiveness will be compromised, so be sure to pay attention to the vibration frequency when making your selection.
3. Which provides better cleaning results: a rotary electric toothbrush or a sonic electric toothbrush?
Extensive testing has shown that rotary electric toothbrushes provide better cleaning results. Of course, if your teeth aren’t strong enough, I wouldn’t recommend them—but I suggest using a rotary brush in the morning and a sonic brush at night. (A lot of plaque builds up in your mouth while you sleep.)
4. There are four key factors to consider when choosing an electric toothbrush:
Vibration Mode (Rotating or Sonic)
Vibration Frequency
Included brush heads (high-quality brush heads are very important)
User-Friendly Gears
Overall,Rotation and Sonic Electric Toothbrush Each has its pros and cons... We recommend choosing an electric toothbrush that suits your individual needs. Here’s an introduction to our Aiwejay factory, which primarily manufactures sonic electric toothbrushes and specializes in contract manufacturing for major brands.
