Summary
The top of the Sonicare line with the DiamondClean brush head that Reddit users say makes their teeth feel like they just left the dentist. Built for people who want the absolute best.
Wirecutter's top pick for children's electric toothbrushes, with a smaller brush head, gentle vibration, and customizable animal stickers that actually get kids excited to brush.
Pros
- DiamondClean brush head delivers a noticeably superior clean per user reports
- Premium build quality with sleek design and travel case
- Multiple brushing modes including whitening, gum care, and deep clean
- Strong community praise specifically for the DiamondClean head's feel
- Smaller brush head and gentler vibration designed specifically for kids' mouths
- Customizable animal sticker designs make brushing fun and engaging
- Built-in 2-minute timer teaches proper brushing habits early
- Rechargeable — no constant battery replacement like cheaper kids' brushes
Cons
- Expensive — $300-$380 is hard to justify for most people
- Replacement DiamondClean brush heads cost more than standard heads
- Smart features and app connectivity add complexity many users ignore
- Diminishing returns over the 4100 for actual plaque removal
- More expensive than basic kids' battery-powered toothbrushes
- Smaller handle may be awkward for older kids or parents helping younger ones
- Replacement brush heads for kids' models can be harder to find than adult sizes
Our take
If you're spending $200+ on a toothbrush, the DiamondClean head is what justifies it. The community is vocal about how different it feels — and that's not nothing.
Getting kids to brush properly is half the battle, and this one wins it. The Design a Pet gimmick sounds silly until your kid is begging to brush their teeth.
