FAQs

What is electric toothbrush called? ›

Two of these options include traditional electric toothbrushes, which are also called rotary or oscillating toothbrushes, and sonic toothbrushes.

Most electric toothbrushes come with 2-pin shaver plugs (not to be confused with 2-pin continental plugs), and these can be easily plugged into a standard 3-pin plug with a 3-pin adapter for electric toothbrush, also known as a shaver adapter.

Sonic toothbrushes have vibrating brush heads that move bristles side-to-side at high speeds. To be classified as a sonic toothbrush, the vibration has to be fast enough to produce an audible hum. Sonic toothbrushes on the market today offer frequencies of up to and over 50,000 movements per minute.

Sonic toothbrushes are a subset of electric toothbrushes with movement that is fast enough to produce vibration in the audible range.

Bass or Sulcular Technique

The Bass method of brushing involves using the toothbrush bristles to scrub off plaque— commonly known as biofilm — from underneath your gums before it can cause gingivitis.

There are two types of electric toothbrushes to choose from: Oscillating-rotary and sonic. Oscillating toothbrushes, as the name suggests, oscillate back and forth to help remove plaque, while rotary toothbrushes rotate in a circular motion.

the toothbrush has a battery powered electric motor as the input device. the toothbrush has a switch that switches the motor on and off. the toothbrush has an oscillating toothbrush head as the output device.

Electric toothbrushes usually use micro low-power drive reduction motors. Commonly used electric toothbrush drive motors include stepper motors, coreless motors, DC brush motors, DC brushless motors, etc.; this type of drive motor has the characteristics of low output speed, large torque, and noise.

Oral-B Electric Toothbrushes use clinically proven superior oscillating/rotating/pulsating technology. The round brush head pulsates to loosen plaque and then oscillates and rotates to sweep the plaque away.

What makes an electric toothbrush vibrate? ›

Through connecting wires (3), this drives a piezoelectric transducer (4) that converts electricity into high-speed vibration. The transducer expands and contracts at very high speed, producing sound waves in your mouth that create gentle cavitation (5) around your teeth, loosening plaque that can be brushed aside (6).

As the circuit rotates 180 degrees, the direction of the current switches; therefore, the direction of the force switches, so it turns around the rotation. This back and forth motion gets transferred to the brush which is why it is so effective in making teeth super clean and white.

Sonic Brush® is the world's first fully automatic toothbrush.

With innovative Flexible VibraClean Bristles, this toothbrush vibrates to penetrate deep between teeth and pulsates to loosen food particles and plaque. This pulsating toothbrush also promotes better oral health by gripping the tooth's surface and lifting away any loose plaque and debris.

Interdental Toothbrush

It resembles a mini bottle brush, with bristles that glide in and out of each tooth. Interdental toothbrushes are a good choice if your teeth are far apart.

Sometimes called an interproximal toothbrush or proxabrush, the interdental (which means “between the teeth”) toothbrush cleans the sides of your teeth and in between them, similar to dental floss.

Battery-powered toothbrushes require you to provide all or most of the brushing action, moving the brush back and forth along all sides of your teeth and gums. In contrast, rechargeable electric toothbrushes provide the cleaning action while you need only guide it along all surfaces.

Studies have even shown that sonic toothbrushes still provide superior plaque removal even when they are held up to 4mm away from the tooth's surface! Obviously, users should brush in full contact with their teeth, but this is a testament to how effectively people can clean their teeth with this technology.

Some examples of Class 1 devices are- Bandages, Electric Toothbrush, Oxygen Mask, Non-electric wheelchair, etc.
