I can advocate that they are crap for teeth hygiene! I had one for about a year and had so many issues. I've switched back to oral b io9

Oral B IO series 5-7 is what I usually recommend to my patients. I use the oral b IO series 9 (received that free from a rep). But I try to understand cost with giving my patients a high quality recommendation. But love it!!! Has a 2 minute timer, oscillates which I think is more beneficial, pressure sensor, bunch of different settings, quieter than most.

Oral B...specifically Oral B iO (have the series 9–goes to series 10). Cosmetic dentist recommended a basic model but I told him I'd been using the expensive Series 9 iO for 2 years.

Ja osobiście używaj io9 od 3 lat i jest to jeden z najlepszych zakupów w moim życiu. Czyści tak dobrze że przestałem myć zęby 2 razy dziennie i nie widzę żadnych problemów, ale pomaga też fakt że nie jem w ogóle słodyczy

Tannlegen min anbefalte også elektrisk tannbørste, men det burde være av den dyrere sorten. Oral-B iO 9 eller høyere. Dyr som fan, men definitivt en oppgradering fra de som koster 200 kr på tilbud

Interestingly, the (Braun) OralB iO are made in Germany, at least the io9 I got from an auction is. P&G is a garbage company, but I have no intention of purchasing the original branded heads, which is what they are actually making money on. (there even is a local company specializing on making the "aftermarket" heads) It's worth noting that all the recent scientific literature seems to be pointing towards oralb having better results, specifically the oscillating-rotating with micro vibrations.

I’d be interested to hear a dentists perspective on Suri toothbrushes if you know anything about them? I bought mine because I needed an affordable new electric toothbrush after my very expensive Oral-B (I think it was probably the equivalent of an iO9 at the time) died after 10+ years. It’s sonic, has a good warranty/replacement policy, lasts far longer after a charge than my oral b ever did and seems to be a sustainable manufacturer. However my teeth feel nowhere near as clean as they did with the oral b and my brushing routine is far more strict now. Before, if I forgot or didn’t have time to floss on a morning my mouth would still feel clean with just brushing. Now if I don’t floss, tongue scrape, mouthwash, brush in that order every single morning and night my mouth feels disgusting and I feel plaque build up within a couple of hours. I know in an ideal world I should do that routine every time anyway and most of the time I did, it just seems since I switched toothbrushes I can’t risk an occasion where I forget or don’t have time
