We provide a full, feature‑rich breakdown of the ProtectiveClean 4100, 5100, and 6100 models—so you can confidently choose the best Sonicare toothbrush tailored to your oral care priorities.
1. Overview: Model Hierarchy & Positioning
- ProtectiveClean 4100 – Entry-level; essential cleaning features.
- 5100 – Mid-tier; adds extra cleaning modes and travel convenience.
- 6100 – Premium of the trio; customizable intensities, mode pairing, travel case.
2. Cleaning Modes & Timers
| Model | Clean | White | Gum Care | Duration |
|---|---|---|---|---|
| 4100 | ✔ | ❌ | ❌ | 2 min |
| 5100 | ✔ | ✔ | ✔ | Clean 2 min, White 2:30, Gum 3 min |
| 6100 | ✔ | ✔ | ✔ | Same as 5100 + 3 intensities |
Additional modes in the 5100 and 6100 enhance whitening (extra 30 s focus) and gum care (gentler, longer session). A built‑in quad‑pacer encourages even brushing.
3. Intensities & Mode Pairing
- Only the 6100 offers three intensity levels (Low/Normal/High) across all modes—ideal for sensitive mouths or shared use.
- The 6100’s BrushSync Mode Pairing automatically selects the optimal mode when detecting a compatible brush head—streamlining usage.
4. Brush Heads Included
- 4100 → C2 Optimal Plaque Control (great for general clean).
- 5100 → G2 Optimal Gum Care (gentler for soft tissue).
- 6100 → W DiamondClean (whitening focus).
All are compatible across models but work best in matching modes (e.g., W head on White mode).
5. BrushSync Reminder & Pressure Sensor
Every model includes:
- RFID BrushSync – automatic brush-head lifespan tracking, alerting replacement after ~3 months or heavy use.
- Pressure Sensor – vibrates handle when brushing too hard.
- 2-minute timer with 30-second quadrant reminders; automatic shut-off ensures full cycle completion.
6. Battery & Travel Convenience

7. Design, Grip & Ergonomics
- All handles share a smooth, non-slip matte finish without added rubber grips.
- The 5100/6100 have a dual-button setup with LEDs indicating mode/intensity; the 4100 offers simpler one-button operation.
- A base ridge on the 6100 prevents rolling on counters—small but useful .
8. Pricing & Value Comparison
- 4100: ~$50 – excellent baseline performance.
- 5100: ~$90 – added modes + travel case.

Industry reviews confirm all three effectively remove plaque; extras in higher models are for comfort and personalization rather than cleaning superiority.
