husband and I have been sharing the same oral-b "genius" or whatever it's called for almost 9 years now (we have our own heads). Both of us have seen immense improvements at the dentist. idk about misuse but my oral-b has 4 different settings the dentist above mentioned (as a patch) if it's too harsh for sensitive gums. It pulses every 30 seconds until 2 minutes is up which helps me with adequate brushing. Just my experience, but maybe the model is more relevant in this situation!

It’s absolutely disgusting. I do not recommend the IO to my patients any longer because of this issue and I run the head in an ultrasonic pod weekly (as well as taking off the brush head, letting it air dry, wiping down the handle, etc. I am METICULOUS and it’s gnarly.) The Oral-B genius series is a lot easier to take care of, but it’s the old series and it’s a lot louder/clunkier of a brush but still effective. I just switched back to my BURST Pro toothbrush, which is a similar toothbrush to sonicare in terms of movements and it has a lifetime warranty if it breaks. If that’s something you’d be interested in giving a shot you could use my promo code KXBGHA. Otherwise, sonicare is also a solid brush, but I would make sure to get one with at least three intensities (which is different from modes!)

Oral B has the pressure light that I’m a big fan of. I personally use a sonicare but have purchased oral b’s for family members who needed the guidance feature. Love both, if you’re new to electric brushing both sonicare and oral B are amazing. Look for coupons for the brush heads, if you can find a great deal stock up and get that brush also

I’ve used the genius and the io in the past

I love both. I recommend oral b with the pressure indicator light- they have the market on it. I had to do surgery on my sonicare. That screw in the center notoriously is faulty. Conclusion: if you think you press too hard, or want more of a feedback on how you’re doing I recommend the oral b. If you just want an excellent brush and don’t care about the pressure go sonicare.

My oral b toothbrushes have lasted me at least 5 years each. I recommend the oral b genius Because I like the toothbrush head style more than the oral b io

That’s pretty average for an electric toothbrush. Rechargeable toothbrushes typically last much longer than replaceable battery toothbrushes, and the rechargeable batteries are more high quality than the replaceable battery versions too. I recommend an oral b genius over the oral b io. It’s cheaper and has a pressure indicator light like the io. It also uses the older “regular” style toothbrush heads (which I prefer over the new heads for the io). It should last you about 4 years too

Everything I bring has to meet my size, weight, and necessity calculation. But after one 3 month trip without a water flosser, I swore I would never do it again and bought a travel one. It's neither as small or as light as I wish, but it comes with me every time. I don't use my water flosser everyday, but I have to use it a couple times a week or my gums feel awful. I upgraded my Oral-B to a USBC charger and that comes with me too.

I've gone through a few electric toothbrushes over the years so I'll share what I've learned the hard way. Right now I use an AquaSonic and my wife uses the Oral-B round clean. Both work great but the difference in battery life is real. I charge mine maybe twice a month, overnight each time. My wife charges hers three or four times a month. That doesn't sound like a big deal until you travel and forget the charger. The AquaSonic just lasts longer between charges and that's been a bigger quality of life thing than I expected. To answer the actual question, yes it's a frugal investment. But not because of the toothbrush itself. It's the replacement heads. That's where the real cost adds up over time. The name brand Oral-B heads are expensive. The AquaSonic heads are way cheaper per pack. So when you're comparing toothbrushes, stop looking at the upfront price and start looking at what the heads cost for a year. That's your actual recurring expense. The dentist in this thread is right that entry level is fine. You don't need the $300 model with six modes you'll never use. Get something in the $30 to $50 range with cheap replacement heads and you're set. The money you save on not needing fillings and deep cleanings pays for itself pretty fast. One thing nobody here mentioned. Wait for a sale. These things go on deep discount during Prime Day and Black Friday every year. I've seen the Oral-B models drop 40 to 50 percent. No reason to pay full price.
