Sorry to do this, but the answer is a very lukewarm “Ehhh, up to you.” No, listen, that’s really the case. The best toothbrush is the one you use consistently.
In clinical trials, there’s a slight, very slight, bit of evidence that says oscillating brushes are maybe better. The scrubbing action removes a ton of plaque, and the circular heads are better for getting in every nook and cranny. If that’s what you want to hear, cool. Buy a rotating brush.
But honestly, sonic brushes do just as good of a job. In all the years I’ve switched between the two, my dentist has never been able to tell. What’s most important is consistency. Use either type of electric toothbrush twice daily and you’re almost guaranteed to have clean teeth. With nothing more than a $50 electric toothbrush, it’s honestly difficult to let them get dirty. So it’s mostly down to personal preference between the two styles.
Oscillating: A dentist-office, deep-clean feel. These brushes are a bit more physical than their vibrating counterparts.
Sonic: Feel a bit more like regular toothbrushes. Not as harsh on the gums but require a bit more work when getting behind and around teeth.
