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 daily cleaning, gentler brushing and help with surface stain removal. It suits users upgrading from a basic electric or manual brush, with useful modes for clean, whitening and gum care. Strong points include the pressure sensor, travel case and up to 2 weeks of battery life. Limitation: it is less feature-rich than premium models with app guidance or more advanced smart tracking.
What it’s great for
- Daily teeth cleaning
- Gentle whitening of surface stains
- Gum care support
- Travel-friendly oral care
- Upgrading from a manual toothbrush
Where it works best
- Home bathroom
- Shared household bathroom
- Travel
- Holiday packing
- Daily commuting routines
Who it’s for
- Adults
- Everyday oral care users
- People with sensitive brushing habits
- Users wanting whiter-looking teeth
- Travellers
Things to consider
It covers the essentials well, but premium sonic toothbrushes may add app connectivity, more brushing modes or deeper personalisation.
Family suitability
Best suited to adult individual use rather than a shared family toothbrush setup.
Orthodontic compatibility
Suitable for general daily cleaning, but people with braces or complex dental work may prefer guidance from their dentist on brush head choice and technique.
Gum care effectiveness
8/10 - Gum Care mode and the pressure sensor support gentler brushing for everyday gum maintenance.
Travel friendliness
9/10 - includes a travel case and offers up to 2 weeks of battery life between charges.
Ease of use score
9/10 - simple mode selection, a built-in timer and battery indicator make daily use straightforward.

- Two-Minute Timer: helps you brush for the dentist-recommended brushing time.

Q: How does White mode differ from the other brushing modes on the Philips ProtectiveClean 5100?
A: On the Philips ProtectiveClean 5100, Clean mode is the standard everyday setting. White mode targets surface stains, while Gum Care adds an extra minute at reduced power for a gentler finish around the gumline.
Q: How does the pressure sensor warn you if you are brushing too hard?
A: The Philips ProtectiveClean 5100 uses a gentle pulsing sound to let you know when pressure is too high. That gives immediate feedback while brushing, which is useful if you tend to scrub harder along the gumline or front teeth.
Q: How soon can the whitening mode make a visible difference?
A: Philips states the ProtectiveClean 5100 can whiten teeth in 1 week by helping remove everyday surface stains. It is aimed at polishing and stain removal, not changing the natural shade of teeth beyond what brushing can lift.
Q: Is the battery practical for travel without needing the charger every day?
A: Yes. On a full charge, the battery can last for up to 2 weeks of normal use, so it suits holidays and work trips. The battery indicator light also helps you avoid packing it away when it is close to needing a recharge.
Q: Is this model a good step up if you want more brushing control than a basic electric toothbrush?
A: Yes. The Philips ProtectiveClean 5100 adds three brushing modes and a pressure sensor, so you get more control than a single-mode brush. That suits buyers who want one handle for daily cleaning, stain removal and gentler gum care.
