2100 Series Electric Toothbrush HX3661/04

I've gotten a few for myself and my kids, and try to find it on sale. Superstore, Shoppers, Amazon depending on if there's a deal.

Sonicare 2100: Szybkość Do 31 tys. ruchów szczotkujących na minutę (nazwałem to obrotami, bo chodzi o cykle pracy silnika magnetycznego) Sonicare 4300: Ruchy soniczne \[ruchów/min\]: 62 000 (też tak to nazywają).

My thoughts exactly. As long as it has the quad-pacer function, any Sonicare model will work fine. My $30 2000 series lasted 5 years before water got into it somehow and fried the electronics. I replaced it with a two pack of the same model and, 4 years later, I’m still on the first one.

I use smart plug. 1.5 hours charger every 2 days. It's a 2015 soniccare and still good. I had to open the other one to fix a rattle so I changed the batteries on both. Still same charging cycle

I love my sonicare. I went for the diamondclean back in 2022 and its still working fine. I don't really use the smart features, if those are important for you then I would get it. I mainly wanted the nice glass cup charging thing. Lets you have a cup for rising and have it be your charging base instead of one of the tiny obnoxious ones that likes to get knocked over. The pressure sensor is amazing, both have that but what I found was super helpful and not something I thought would be is the timer for when to brush where. The previous sonicare series 2 I used had 4 brushing zones. The 6 on the diamond clean seems to help a ton with making sure I brush properly. Partitions brushing time into 6 smaller sections 3 for top and 3 for bottom. I gifted my sister one (Flexcare+ which is discontinued) as well back in 2017 and hers just died a few months back if you wanted an idea on lifespan

I looked specifically for one with a travel case, but those are usually the higher end (Sonicare 9900 and the like). I tried a cheap one from Concept but it cleaned noticeably worse than my Sonicare. Then last year I snatched a new Sonicare for 50 euros at a clearance sale and I'm very happy with it. This one has a built in USB A cable to charge.

As a dentist with 10 years of experience conducting clinical trials, I’d push back on this a bit. The evidence doesn’t really back up the recession claim that strongly. Multiple studies and systematic reviews comparing oscillating-rotation (Oral-B) to sonic brushes (Sonicare) haven’t found a meaningful difference in gum recession outcomes between the two. If Oral-B were causing recession in ‘many people,’ you’d expect that to show up pretty consistently in the research and it doesn’t. The other issue is confounding variables. Patients who develop recession may simply be brushing too hard regardless of which brush they use. Seeing recession in Oral-B users in a clinical setting doesn’t tell you whether those same people would have been fine with a Sonicare. They might just be aggressive brushers. Also worth noting that Oral-B’s pressure sensor gives immediate feedback when you’re pressing too hard, which could actually be more protective for people who naturally brush aggressively. The mechanical argument makes theoretical sense since oscillating rotation is a more forceful action, but there’s a gap between a plausible mechanism and a clinically proven real-world effect. ‘Many people’ is a pretty strong claim for what is really just anecdotal clinical observation
