If you buy an electric toothbrush, get one that rotates in circles

I’ve always wondered whether my Sonicare toothbrush was better than a normal, non-electric toothbrush. Turns out – like most things in life – it’s how you use it that matters most.

The only type of electric toothbrush that’s proven to reduce more plaque than a non-electric is the “rotating, oscillating” kind. My Sonicare sure isn’t :)

And the kicker? Dentists and most experts aren’t sure this increased plaque reduction really matters in the long-term (with respect to things like gum health, incidence of cavities, etc)…
