Best Toothbrush
This is the best toothbrush I have owned. It’s the 2nd one in our house. Very quiet, great clean with a whitening function. I looked at many options but came back to this everytime.

Works really well
Have been using this for a month and so far it is working extremely well. It’s quiet but effective at cleaning teeth. This was purchased to replace another brand which the battery failed in after only 3 years - considerinh it was $350 I wasn’t impressed.

Great piece of tehnology.
The various features all come together to provide an efficient teeth cleaning and whitening experience. Easy to understand and use. I've definitely already noticed an improvement in my gums and a whiter teeth colour than I previously had.

At a glance
A mid-range sonic electric toothbrush for adults who want better everyday cleaning, gentler brushing and help with surface stain removal. It suits users who value pressure feedback, simple mode choices and travel convenience. Key strengths are gum-friendly cleaning, whitening support and up to two weeks of battery life. One limitation is that it offers fewer advanced smart features than higher-end models.
What it’s great for
- Everyday Oral Care
- Gum Care Support
- Surface Stain Removal
- Travel Use
- First Electric Toothbrush Upgrade
Where it works best
- Home Bathroom
- Shared Family Bathroom
- Travel
- Apartment Living
Who it’s for
- Adults
- Everyday Brushers
- Users With Sensitive Gums
- Travellers
- People Upgrading From A Manual Toothbrush
Things to consider
It covers the key brushing essentials well, but it is a discontinued model and lacks the deeper app connectivity and wider mode customisation found on more premium sonic toothbrushes.
Family suitability
Well suited to adult households and shared bathrooms, though each user should have their own compatible brush head.
Orthodontic compatibility
Suitable for general use around orthodontic care, but specialist brush heads or dentist guidance may be better for braces and complex dental work.
Gum care effectiveness
8/10 - Pressure feedback and a dedicated Gum Care mode make it a strong option for gentler everyday brushing.
Travel friendliness
8/10 - The included travel case and up to 2 weeks of battery life make it convenient for short trips.
Ease of use score
9/10 - Simple controls, three clear modes, a timer and battery indicator make it easy for most users to operate.
Key benefits
- Pressure Sensor: Alerts you when brushing too hard, helping protect teeth and gums from excess pressure.
- Three Brushing Modes: Lets you choose Clean, White or Gum Care to better match your daily oral care needs.
- White Mode: Helps reduce surface stains for a brighter-looking smile with regular use.
- Gum Care Mode: Adds an extra minute of gentler brushing to support more comfortable gum care.
- Two-Minute Timer: Encourages brushing for the dentist-recommended 2 minutes.
- Rechargeable Lithium-Ion Battery: Delivers up to 2 weeks of use between charges, making routine charging less frequent.
- Travel Case: Makes it easier to keep the toothbrush protected and packed for trips.
- Advanced Sonic Cleaning: Uses sonic brushing action to help remove plaque and clean along the gumline effectively.
Q: Does this toothbrush have app control or smart brushing tracking?
A: No. Philips ProtectiveClean 5100 focuses on core brushing features such as a pressure sensor, a timer and three modes. It does not add app connectivity or advanced tracking, so the experience stays simpler and more hands-on.
Q: What does White mode actually do in everyday use?
A: White mode is designed for removing surface stains during daily brushing. It is aimed at polishing and a brighter-looking finish rather than bleach-style whitening, so it will not change deep or intrinsic discolouration.
Q: How does the pressure sensor alert you if you brush hard?
A: Philips ProtectiveClean 5100 gives a gentle pulsing sound when pressure is too high. The alert is there to prompt a lighter brushing technique, rather than forcing the brush to stop or switching modes automatically.
Q: Does Gum Care mode run longer than the standard Clean mode?
A: Yes. Gum Care mode adds an extra minute of reduced-power brushing after the standard cleaning time. That makes it the better fit if you want a gentler finish around the gums rather than a quicker routine.
Q: Will BrushSync remind me when the brush head needs replacing?
A: Yes. HX6851/56 includes a BrushSync feature that works with compatible Philips Sonicare heads to prompt replacement timing. It is a reminder only, so the head still needs to be changed manually when the alert appears.
Q: Is the included travel case also a charging case?
A: No. The included case is for storage and travel protection, while charging is handled by the separate supplied charger. That is handy for trips, but it is not the same style of case that recharges the handle on the go.
Q: Is there a real step up from basic Sonicare models?
A: Yes. ProtectiveClean 5100 adds features that simpler Sonicare models may not include, such as a pressure sensor, White and Gum Care modes, BrushSync and a travel case. It still stays more straightforward than app-led premium brushes.
