EXAM – Brushing your teeth is one of those essential daily tasks. If you follow the guidelines, you will do this twice a day. Numerous studies have indicated that today’s electric toothbrushes do a better job of cleaning than manual brushes. Why? Because they brush more vigorously than you can with just your hand. Today we are going to take a look at the Oclean Flow Sonic Electric Toothbrush which uses sonic technology to deliver 38,000 strokes per minute to make your pearly whites sparkle. Let’s brush our teeth and see if sound can deliver a clean mouth!

What is that?

The Oclean Flow Sonic Electric Toothbrush is an electric toothbrush that uses sonic technology to vibrate the brush head. This provides 38,000 strokes of cleaning motion per minute without the user having to move the brush beyond positioning.

Design and features

The Oclean Flow sonic electric toothbrush consists of two parts: the control handle and the brush head. The model sent to me came with only one head. They offer packages with four additional heads. As you can see, I was sent the white version. They also offer it in blue and red.

To use the brush, position the front of the brush so that it is flush with the front of the handle and slide the head over the blade. I find it interesting that the head has an alignment arrow but the handle does not. Weird. Still, it’s obvious how to install the head.

The assembled unit is the size of a toothbrush. If you look at the photo above, you can see the round power button just above my thumb. Below we see five symbols which also have LED lighting behind them. They indicate cleaning mode, top to bottom, morning, evening, standard cleaning, whitening, gentle. Morning mode is designed for modest cleaning, to remove overnight buildup from your teeth. Night mode is the most vigorous, designed to blast away the dirt of the day. Standard mode is an intermediate cleaning mode. The whitening mode is supposed to do a better job removing stains from smoking, drinking coffee, etc. Soft mode reduces power for those with sensitive mouths.

When you press the power button, the brush speeds up for three seconds and the LED behind the mode lights up dimly. In the photo below you can see the power indicator, but the mode is almost impossible to see. For the record, it was in top mode, Morning.

If you press the power button again within five seconds, the brush will switch modes up and down. After five seconds, the button turns off the brush. The Oclean Flow sonic electric toothbrush remembers the last mode used and powers on in that mode.

The power indicator is much easier to see. This ring flashes when charging and flashes red when the battery is nearly depleted. Between full and empty, there is no battery charge level indicator.

The USB-C charging port is located at the bottom of the handle. It’s covered in a sturdy rubber cover that snaps securely into place.

The bristles are soft nylon.

In the photo above you can see them vibrating.


Other than charging the handle and slamming on the head, there’s no setup.


I have been using an electric toothbrush for years. My wife clung to a manual brush. Reviewing the Oclean Flow Sonic Electric Toothbrush was an opportunity to bring my wife to the diet side, so she is the primary user of this toothbrush. I have to say that her first impression was not favorable, she was jumping in the bathroom like a small child who had just tasted something he didn’t like. Why? She has a reasonably sensitive mouth, especially the roof of her mouth. If you’ve never tried a sonic toothbrush, the feel of this one, especially in sensitive areas, can only be described as bizarre. The noise is weird. The tickling you feel is weird. The tingling that goes through the roof of your mouth is weird. She lasted less than 30 seconds on her first attempt. She backed off to the gentle mode and eventually moved on to more vigorous modes as she got used to the feeling.

It lasted about a week. But…she said that after running her tongue over her teeth, her teeth were pretty clean – maybe cleaner than her usual toothbrush. Now that she’s gotten used to the feeling, she does the full two-minute cleaning cycle regularly and her teeth are very clean.

Speaking of the two-minute cycle, general recommendations state that you should brush your teeth for two full minutes – 30 seconds for each quadrant of your mouth (upper right, lower right, upper left, lower to the left). The Oclean Flow has a 30 second indicator where the brush pauses briefly at 30 second intervals so you know when to change quadrants. The break is so brief that she completely missed it. Now that she’s been using it for a while, she resumes pausing about half the time. It really needs to be a little longer. After two minutes, the brush turns off.

One thing she really likes is the design of the brush head. Its longer and narrower design allows it to reach the back of its back teeth much more easily than its manual toothbrush.

Claimed battery life for the Oclean Flow sonic electric toothbrush is exceptional at around six months between charges, based on twice-daily use at the lowest intensity level. I had planned to turn the brush on and let it run until it died. Since it turns off after two minutes, it wouldn’t work. We’ll just have to take that claim as most likely valid.

What I like

  • Brush head design reaches back teeth
  • Does a great job of getting teeth clean
  • The set is well balanced
  • Good battery life and USB-C charging make it easy to travel

What I would change

  • Add a charge level indicator
  • Make mode lights brighter
  • The 30 second indicator should be more definitive
  • An included travel case would be nice

Final Thoughts

For the record, my hand is holding the Oclean Flow sonic electric toothbrush.

Let’s face it, my wife was ready to throw the Oclean Flow in the trash after her first attempt at using it. A sonic toothbrush sounds weird and she didn’t like it. But with a little patience, she is now reaping the benefits of an electric toothbrush. She feels that her teeth are cleaner. She also feels that the brush has helped reduce some of the sensitivity in her mouth. His next visit to the dentist will validate him.

There is little debate that electric toothbrushes do a better job than manual brushes. If you’re looking for an electric toothbrush that uses sonic technology and offers great battery life, the Oclean Flow Sonic Electric Toothbrush is worth a look.
