With an estimated 3.5 billion electric toothbrushes sold worldwide last year, the market is continuously growing with plenty of choices at a variety of prices. With that in mind, I regularly scan the dental aisles in various shops to keep up to date with what’s on the market. It’s also where I usually meet a poor soul scratching their head trying to work out which electric toothbrush they should buy. I take mercy on them and step in to offer my expert opinion. Let’s break down some points:
Types of electric toothbrushes
There are several different mechanisms but to keep it simple the two leading types are rotary/oscillating heads and sonic vibration heads.
Rotary/Oscillating heads are small and round, rotating in one direction and then the other, one tooth at a time to sweep plaque away. Often these heads pulsate too.
Sonic heads vibrate at certain high speeds and frequencies to break down plaque as well as agitate the toothpaste and fluid in the mouth to clean between teeth and along the gumline.
So which is more effective? Both will remove more plaque than a manual toothbrush but in clinical trials, sonic brushes removed significantly more plaque – therefore more effective.
