I repped our state Dental Association as a contract lobbyist during the last legislative session and the dentists almost unanimously preferred the Sonicare. I have a good enough relationship with them that I trust they were not just giving me a paid endorsement.
Awesome.
I was liking this one (
Philips Sonicare 3 series Gum Health) or this one (
Philips Sonicare 5 series Healthy White)... I don't care for extra bells and whistles, but it seems to be the case that the 5-series model has a better build, and I think I'd like extra button to help vary the speed so I don't have to cycle through button presses every time.
Only bummer is that it appears Sonicare replacement heads are generally more expensive than the Oral-B heads. But, then again, I've never had terrific oral hygiene, and I'm trying to correct that, so less scolding at the dentist will be worth it.
FWIW: right now I'm using a Spinbrush, perhaps it was $15 or so? Not bad at all, better than manual by far, but I'd like to get something that is actually build to last and might just have better cleaning ability. There does appear to be some science behind the "sonic" vibration approach, as that motion has a secondary effect that helps, through fluid dynamics, clean out areas just a tad out of reach of the actual bristles. Tiny little improvements, when it comes to brushing, go a long way.
