Ultrasonic vs. Sonic Toothbrush – Pros and Cons


|   Written by:


When learning between sonic vs. ultrasonic toothbrush, it’s easy to assume that one is more effective than the other. However, is a sonic or ultrasonic toothbrush manufacturer the better choice? Consumers look for dental health essentials that are easy to use, affordable, and value worthy. Therefore, it’s important that you choose the right product to sell or use in your facilities.

There are several aspects of ultrasonic vs. sonic toothbrush that you should learn. This guide is what you need that differentiates these two types of toothbrushes.

Difference between ultrasonic and sonic toothbrushes

Toothbrushes are a mainstay when talking about oral hygiene. It is a tool that cleans the teeth and removes plaque. Dental care experts recommend brushing at least twice a day for two minutes each time. Other than duration, one also must brush thoroughly to prevent food bits from accumulating in the hard-to-reach corners of the teeth.electric-and-manual-toothbrush-on-blue-background

For this reason, it’s ideal to market a toothbrush that is efficient and fuss-free to use at the same time. The sonic toothbrush and ultrasonic toothbrush are a step up from regular toothbrushes. They have added features that enhance the benefits of brushing.

Technically, they are both electric toothbrushes. Still, these types of toothbrushes have marked differences despite their similar names. The question is: what’s the deal with sonic vs. ultrasonic toothbrush?

In general, these electric toothbrushes produce a ‘humming’ sound when used. This low noise is the result of the sonic vibration that the powered toothbrush gives off. Studies show that a person can hear such vibrations at a range of 16 Hz-20 kHz frequency range. A sonic toothbrush can have a rate of up to 20,000 Hz. Anything with sonic vibrations above this rate is already an ultrasonic toothbrush.

Sonic toothbrush

Sonic toothbrushes are commonly referred to as electric toothbrushes. Typically, the brush head creates amplitude movements responsible for the humming sound. When you operate this toothbrush, you can hear a light buzzing from the bristles area.

The motion or vibration for sonic brushes is around 24,000 to 48,000 movements per minute. That’s about 12,000 to 24,000 oscillations, or the back-and-forth sway of the bristles area at a constant speed. The brush does its cleaning action using a sweeping motion. In this type, the amplitude movements allow the brush to create larger sweeping actions.woman-using-electric-toothbrush-at-home-technolog

In general, sonic toothbrushes have an electromagnet, a resonator, and a spring working together. The magnet rocks the brush and creates a sonic wave through its consistent movement. The frequency and amplitude of the vibration swirl toothpaste and saliva around. Consequently, it allows more thorough cleaning of teeth from all sides.

The sonic electric toothbrush cleans more effectively than a regular toothbrush, given its fast movement. It creates ‘hydrodynamic forces’ that disrupt the plaque in hard-to-reach areas.

Benefits and drawbacks

The target market for sonic toothbrushes includes people who form tartar more easily. The brush’s mode of action prevents plaque from building up and hardening over time. Here are the pros and cons of this toothbrush.


  • It thoroughly removes soft and hard plaque
  • A sonic toothbrush offers effective cleaning via circular or sweeping movements
  • Blocks stone formation that ages the teeth
  • Ergonomic design and ease of use
  • Customizable with plenty of attachment options


  • May cause uncomfortable tingling sensations
  • More expensive than regular toothbrushes
  • Some people wrongly believe the brush is ineffective

Ultrasonic toothbrush

Unlike sonic ones, the ultrasonic toothbrush does not depend on the sweeping action of the bristles. Instead, it operates using ultrasonic waves produced through a very high vibration frequency rate of at least 20,000 Hz. It’s capable of producing about 2,400,00 movements every minute. If you notice, these numbers are much higher than what the ultrasonic toothbrush delivers.bamboo toothbrushes and electric toothbrushes

Based on scientific research, ultrasonic waves of around 1.6 MHz are therapeutic. That’s the reason why the Food and Drug Administration in the US specifies this frequency as the minimum requirement for ultrasonic toothbrushes.

Generally, an ultrasonic toothbrush manufacturer outfits a piezoceramic transducer into the brush. It is installed in the handpiece or body. This part is responsible for producing waves that are too high to be audible.

Accordingly, this frequency rate can help relieve pain and inflammation. It can also fight spasms and allow better blood circulation. These brushes heat the gums just enough to keep them healthy and clean. The low amplitude ultrasonic waves are capable of breaking bacterial bonds without requiring physical contact between the brush and teeth.

As a result, it prevents dental plaque from building up in hard-to-reach areas. This brush also cleans more effectively between interdental spaces and braces.

Benefits and drawbacks

While ultrasonic toothbrushes are less common, they come with benefits that are a great selling point for customers. They don’t rely on physical motion, although some ultrasonic models include sonic vibration to optimize the cleaning action.


  • Removes soft and impacted plaque more efficiently
  • Breaks bonds of bacteria in the oral cavity to prevent plaque formation
  • Distributes cleaning fluids thoroughly below the gumline for a deeper clean
  • Highly effective for keeping braces and dentures clean
  • Customizable with several modes of operation and power switches


  • May take longer for a consumer to brush (5-10 seconds for each area)
  • More expensive than regular toothbrushes
