The Best Electric Toothbrush Currently?
My Sonicare is almost 10 years old and has zero functionality issues. There’s a couple cosmetic issues (yellowing handle and the rubber around the button got pressed inwards) but it is what it is, and I think they’ve addressed this on newer models, at least the rubber. We have the 2 Series which is probably the equivalent to the 4100 series now. The battery still lasts weeks at a time which is nice. My charger plugs into the wall but I think the newer ones work off a usb phone charger block. It’s not the most compact electric toothbrush out there and the case it came with is not space efficient and no longer latches (though I think I messed it up and now it’s warped), but the never models look slimmer with better cases.

Sonicare vs OralB - which one is worth the money?
I have had 5 sonicares over 15 years. 2010-2016: I got a twin pack for Christmas. I gave one away. The other one still worked but I wanted to upgrade at the end of 2016. 6100. 2016-2024: it stopped charging. 9000. 2024: It still works but I wanted to upgrade so now it’s a travel brush. 4100 2025: I just got the 9900. A few tips: Don’t leave it submerged in water for too long. I have read that the screws in the handle become loose if you regularly tap the handle against the sink to get the water off.

Best electric toothbrush?
I’ve gone through a few over the years, and the one that’s held up the best (and actually improved my dental checkups) is the **Philips Sonicare 9900 Prestige**. It’s definitely a premium pick, but the build quality is excellent, the brushing performance is top-tier, and the pressure sensor actually *helps* prevent gum irritation. Mine’s been going strong for over 3 years without a single issue. If you want something still high-end but not quite as expensive, the **Sonicare ProtectiveClean 6100** is a great middle ground. Durable, reliable, and has enough settings to customize without overcomplicating things. For a non-Sonicare option, the **Oral-B iO Series 8 or 9** is also fantastic. It has a round brush head (like what most dentists use), and the real-time feedback helps a lot if you’re trying to improve your technique. Just know the replacement heads are a bit pricier. BIFL-friendly picks people consistently recommend: * **Sonicare DiamondClean Smart** – sleek, powerful, built to last * **Oral-B Pro 1000** – super basic but dependable, and easy to fix/replace parts * **Foreo ISSA 3** – silicone brush head, super durable, charges once a year (yes, really) What matters most: get one that’s easy to clean, has a long battery life, and won’t brick on you after a couple years. Anything from Sonicare’s or Oral-B’s upper tiers usually checks those boxes.

Best Electric Toothbrush To Buy 2025?
For great cleaning and smart features, the Philips Sonicare 9900 Prestige and Oral-B iO Series are top picks. If you want something more budget-friendly, the Philips Sonicare ProtectiveClean 6100 is a solid option. Replace the brush head every 3 months for the best results.
