Battle of toothbrush tech (oscillating vs sonic toothbrush)

With the advance of technology, it comes with new tools to help in brushing. Electric toothbrushes have evolved to include built-in timers, pressure sensors, expanded brushing modes, and Bluetooth-connected apps to increase brushing time and thoroughness. The majority of contemporary electric toothbrushes are classified as sonic(side-to-side motion) or oscillating-rotating (O-R).

What is oscillating rotating toothbrush

Oscillating rotating toothbrushes have bristles which are usually arranged in a circle on a head which oscillates back and forth. Other technologies have been incorporated over the years, such as ‘3-D’ by Braun which combines oscillating, vibrating, and pulsating brush head movements to remove more plaque than a single head motion. Oscillating toothbrushes generally have a brushing action ranging from 2500 to 7500 rotations per minute. Current market brand leader for Oscillating toothbrush are Oral B and Philips.

What is Sonic toothbrush

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. In addition, sonic toothbrushes also employ another method which is to use a technique called ‘fluid dynamics’. This is a secondary cleaning action which reaches far beyond what a mechanical scrubbing motion can achieve. The high frequency and intense vibrational speed of the bristles ‘agitate’ the water and other fluids in the mouth to the extent that its reach extends beyond the actual brush contact points.

How to choose?

For those who emphasize cleaning efficiency, oscillating toothbrush provides a superior cleaning compared to sonic toothbrush. However, the price of oscillating toothbrushes is often quite high compared to sonic toothbrushes with basic functions. People with severe gum recession are often advised to use sonic toothbrushes as it is gentler on gum and teeth surfaces, less abrasive brushing compared to oscillating toothbrushes if oscillating toothbrush is used incorrectly. Other factors such as added functionality including brushing monitoring software and battery life can be taken into consideration.

Final words

The advancement of electric toothbrushes indeed helps in removal plaque more efficiently, but this should not be the only measure in maintaining oral hygiene. Flossing plays a even more important role as the most advanced electric toothbrushes can never reach the space between the teeth. Most cavities formed in the gap between teeth.
