Do I Need an Electric Toothbrush?

When it comes having a consistent dentist-quality cleaning, nothing works quite as well as an electric toothbrush. Look right below for the very best deals on brand new electric toothbrushes!

What Makes a Good Electric Toothbrush?

What makes a good electric toothbrush for one person will be different to another. The most important thing to look for when choosing an electric toothbrush is twofold: 2 minute timer and a quadpacer. Of medium importance is the following: Pressure sensor, Good battery life, Travel case, Price, Additional cleaning modes, Brushing intensity, Cost of replacement brush heads. Of lowest importance is Brush handle shape, size and color, Brush head shape and size, Battery charging/status icon, Smart features, Bluetooth, Motion tracking, Smart guides, UV sanitizers, Automatic power off, Charging stands, Water resistance, Noise, LEDs/cleaning mode display, Storage compartments, Dual handles.

Cleaning Technology & Brands

The ultimate job of a toothbrush is to effectively clean plaque, bacteria and debris from the teeth and gums. All leading brands do a good job in achieving this and from our point of view, and clinical studies support this. Given the equivalent results the different cleaning technologies provide, the way in which they go about it holds a low importance when choosing an electric toothbrush. You may have a preference for one brand or particular cleaning action, but don’t let it rule the decision making process. Primarily, the decision is between Sonic and Oscillating-Rotating toothbrushes, but there is a newer, less common type of toothbrush, known as ultrasonic.


This kind of toothbrush uses 2 methods to clean the teeth. The first is a mechanical side-to-side cleaning motion of the bristles to remove plaque by essentially sweeping and scrubbing the surfaces, like a manual brush (although the motor moves the bristles, not you). The second is a non-contact approach that uses the sonic technology to disrupt plaque beyond the tips of the bristles. To achieve this secondary cleaning motion, the brush head must vibrate at a speed that falls within the range of frequencies that humans hear (20-20,000hz). This intense vibration agitates fluids that surround the teeth and can loosen and remove dental plaque in locations that are beyond the physical touch of the toothbrush. The brush head on a sonic brush is typically a lot like a manual toothbrush in its size and shape. It was Philips, under the Sonicare brand, that first brought this to market in 1992 and even today remains the leading brand of sonic toothbrush, although others like Colgate & Omron also use such technology.


This kind of toothbrush has a small, round brush head that moves back and forth (side to side movements) in a circular motion to help remove plaque and dental debris. It is Oral-B who have championed such and developed it to be as popular as it is. This oscillating-rotating movement is referred to as ‘2D’ cleaning by the brand. Add in Pulsations (essentially vibrations) and this now becomes ‘3D’ cleaning. Pulsations offer a more sophisticated motion and gives another dimension to the brushing. Whereas the 2D cleaning requires the physical movement of the brush head against the teeth, pulsations are essentially a ‘non contact’ form of brushing. It is a non contact brushing as the high frequency pulsations generated by the brush agitate fluids that surround the teeth and can loosen and remove dental plaque in locations that are beyond the physical touch of the toothbrush. Pulsations are essentially Oral-B’s description for sonic technology, but they do not refer to it as such, as it was a competitor that brought this approach to market.
