Dentists pretty much universally recommend electronic toothbrushes, in my experience.

Interesting, the dentists I have asked (4) all said it doesn't matter (Spain and Germany, maybe it's relevant) at all and it's up to personal preference.

I’d recommend to switch dentists maybe. Philips Sonicare is such an improvement for teeth hygiene - how could I live without?

Also: floss and mouthwash. Like floss is really important…

I was traveling in the EU a year ago and was in need of a toothbrush. The one I picked up at an arbitrary pharmacy in Antony, FR has nothing special about it but has lasted (I mean the bristles are not wearing hard or splaying, getting soft, whatever the usual failure mode for a toothbrush is) in 12 months of use. And I'm usually pretty hard on my brushes.

Why can't we in the US just have nice cheap things. Why is everything an electronic life-hack with a fun take on how to be eco-concious, that involves buying something I don't already own?

For what it's worth, the toothbrush was also not the cheapest I could find (that would have been Lidl or somesuch), and was made in France, so maybe that makes a difference.

Also, dentists recommend X-rays A LOT, too.

The usual problem with toothbrush bristles is they become microscopically worn down, so they don't scrape off plaque as effectively. Even if you can't see the problem, it might not be working as well as a fresh head will.

You can find electron microscope scans of fresh toothbrushes and worn ones in this[0] Applied Science YouTube video.

Maybe in Europe they're not all selling Sonicare on commission like they do in the US.

More doctors smoke Camels than any other cigarette.

A very disingenuous comparison.

As your Dentist I would recommend Viceroys.
