My Phillips sonicare diamond clean has a charging cup and travel case! I’ve had it a few years now and I love it (it’s [this one](https://www.target.com/p/philips-sonicare-diamondclean-smart-9300-electric-toothbrush/-/A-91735623?preselect=89376318#lnk=sametab), I got mine at Costco). I have a similar problem bathroom and my personal rec would be to put the charger in another room (bedroom on a dresser works well!). This keeps it away from the toilet but removes the possibility of mold growth from keeping it in an enclosed space. The cup is dishwasher safe and I find it keeps any drips contained well!

I got a Sonicare DiamondClean 9300 as a Christmas gift a few years ago, and at first I thought it was ridiculous. It comes in this fancy glass that doubles as a charger, a leather travel case, and has like five different brushing modes including “gum care” and “whitening.” I rolled my eyes hard. But after using it for a while, I actually noticed my gums stopped bleeding completely and my hygienist said my tartar buildup was much less than usual. I think part of it is that Sonicare’s vibrations are more subtle than Oral-B’s rotations—it feels like it’s flushing out debris between your teeth instead of grinding on the surface. It’s expensive, and I’d never have bought it myself, but now that I’ve had it I don’t think I could go back. The replacement heads are pricey, but I found generic ones on Amazon that work just as well. If you want the “luxury” electric toothbrush experience, this one is the Apple product of the category.

I love the deep clean mode they have on the 9300 models and above. That said, the 7500 series has the same deep clean but they only trigger it for the last 30 seconds of a 2 minute brush cycle, it's literally a paywall. For that reason, I do really like the DiamondClean series, but heavy asterisk!

go for [Philips Sonicare ](https://www.reddit.com/r/recsmatter/comments/1pswa4s/philips_sonicare_diamondclean_smart_9300_premium/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button)rather than Oral-B many people prefer philips sonicare over oral b because the sonic vibration action feels gentler on gums while still removing more plaque than a manual brush sonicare tends to be better on the gums and generally more thorough, while oral b sometimes feels more intense but isnt always as comfortable for daily use.

näin necrobump niin io sarjasta 6 on se kultainen keskitie hinnan ja ominaisuuksien näkökulmasta, saat suurimmanosan lippulaivamallin ominaisuuksista mutta ilman isoa hintaa. isoin hyöty jos hyppää 9 on että saat 3d seurannan harjaamiseen 6 vyöhykkeen sijaan.

Ive always used Oral B but I felt like I needed to make a change. I did some research and found that the Phillips one was better for people with braces. Well I made the switch and they’re right! My teeth feel cleaner honestly. The C3 brush works better I think.

Oral B makes a good option too. I personally use the cheapest sonicare Diamond clean, mostly because the higher end models just have additional settings I never use. The cheapest model comes with 2 speeds (I use the higher speed) and some other shit I don't care about.

I’ve had two Phillips diamond cleans break on me, but my partners have held up just fine. Bought the model a tier down literally today - seems like it does the same thing for half the cost
