Summary
The flagship Sonicare with the most advanced sensor technology and app integration available. Built for people who want real-time brushing feedback and the absolute best Sonicare has to offer.
A previous Wirecutter pick that remains a solid, no-frills Sonicare option for families wanting a vibrating brush without paying for the premium Design a Pet Edition. Reliable and straightforward.
Pros
- Most advanced pressure and motion sensors in the Sonicare lineup
- Deep app integration with real-time brushing guidance
- Premium build quality and design
- Multiple brushing modes for every oral care need
- Proven Sonicare sonic vibration technology
- Built-in two-minute timer for proper brushing habits
- Rechargeable — no constant battery replacement
- Former Wirecutter pick with a strong track record
Cons
- Very expensive at ~$380 retail
- Most people won't use the advanced smart features enough to justify the price
- Replacement brush heads remain costly
- Overkill for casual users
- Lacks the fun customization of the Design a Pet Edition
- Fewer kid-engagement features than the newer model
- Replacement heads still pricier than Oral-B equivalents
Our take
At $380, this is a hard sell for most people — but if you're serious about your oral health and want the most data-rich brushing experience Sonicare makes, the 9900 is it.
If the Design a Pet Edition is sold out or over budget, this standard Sonicare Kids model is the same great brush underneath — don't overthink it.
