The SoniCare ProtectiveClean 4100 in a nutshell provides what you need, without the bells and whistels but at a price that will make you easily forget the small features that are left out of this toothbrush.

This model consists of basic fundamental features but that is the important thing. The same technology that is used in the more expensive models is still here but so are the huge price tags that come with them. You still get the straightforward brushing mode, pressure sensor, and a timer with QuadPacer. The elegantly designed 4100 is waterproof as well so you can take it wherever you want without any worries. 

Basics aside, a notable feature added on this model is the BrushSync technology which essentially reminds you to replace your equipped brush head every three months or so. This is something commonly placed along with other Sonicare ProtectiveClean series but is not that budget-friendly.

All these amazing features you can get in one toothbrush at a reasonable price. It is totally risk-free, and we highly recommend it.



Look/Toothbrush at a glance

Getting the ProtectiveClean 4100 is relatively easy via Amazon, and once your package has arrived, you will see how delicately packed your contents are inside the protective box. After unboxing, you will get the following items:

  • Sonicare ProtectiveClean 4100 brush handle
  • 1x C2 optimal plaque control brush head
  • Sonicare issued charger
  • Toothbrush manual

Now let us venture deeper into our main toothbrush. At first glance, the rich colors painted on the handle will amaze you visually. This is well-complemented by the structure of the 4100 model: elegantly-shaped and extremely comfortable to hold that it would not even slip because of the strong rubber grip.

On the same brush handle is the power button to switch on or off the electric toothbrush. Although it is limited to its default cleaning mode, it totally packs a punch for a next-level brushing experience because of its mind-blowing features that we will cover for you later.

Brand Quality

Throughout the years Sonicare has dedicated on including the BrushSync technology to the ProtectiveClean series, 4100 stands out the most – and we are not surprised. As usual, the extra feature costs lots of fortune, but this model has less significant price all thanks to its single cleaning mode. It may sound too plain for people who want extra brushing options to choose from, but at least it does a straightforward job.

Overall Amazon Reviews

Sonicare's ProtectiveClean 4100 is perhaps one of the most successful toothbrushes in the Amazon, garnering 4.7 stars out of 5 from over a whopping 40,000 users. As described by their valued customers, 4100 is a no-nonsense, wallet-friendly rechargeable electric toothbrush with an added spice. That spice is BrushSync, something that is not commonly present among Sonicare's electric toothbrushes. 


Ready to try the well-sought ProtectiveClean 4100? Then check Amazon as they have the lowest price for this toothbrush. In all our reviews nothing came close to the value of a toothbrush you can get for $39.95

  • Standard kit ( all you really need for one person)

White - $39.95

Pink - $39.95

Black - $39.95

  • With extra brush head for a non-stop quality brushing

White - $64.94

Pink - $64.94

Black - $64.94



Every portable electronics needs a battery to work. It is stated in the Amazon that ProtectiveClean 4100 requires a Lithium-Ion battery. The good news is you will not be bothered to buy one because it is already included in your toothbrush model. With the battery's strength, the 4100 will be functional for 14 days or more (depending on use) before charging again.

Some tips while charging the toothbrush:

  • A solid green LED flash means full battery.
  • Green-colored LED flashing means the battery is half empty.
  • Amber LED accompanied with three beeps, means you are almost out of brushing sessions.
  • Amber LED along with five beeps, means you better charge the electric toothbrush so you can use it for another two weeks.

Kindly note that it will take you approximately 24 hours to charge the 4100 model, and you can leave it plugged in if you like. We assure you that it will not break.



  • No-nonsense Default Cleaning Mode

Every desirable looking and well-polished teeth start with a single click to the power button, proceeds to enable the cleaning mode, standing in front of the mirror, and let the toothbrush do its job. Specifically, 4100's default Clean Mode has a superior brushing performance than manual toothbrush action for better results. It will take you two minutes to finish one session of Clean Mode.

  • Pressure Sensor

At most times, it is not easy to know whether ProtectiveClean 4100's pressure sensor indicated that you applied excess force while brushing your precious teeth. This is one of the downsides of the electric toothbrush, but it still does its job very well in providing advance oral health care.

  • 2-minute timer with QuadPacer

The Clean Mode in 4100 model (and any other Sonicare models) lasts for two minutes. The brushing duration is the suggested time by oral health experts to remove stains and dirt from the teeth thoroughly. 

The QuadPacer, on the other hand, makes sure the four sections inside your mouth received a deep, meticulous 30-second clean with the cleaning power of ProtectiveClean 4100.

  • Long-lasting Battery Life

One Lithium-Ion battery packed inside the 4100 can greatly turn the tables for quality oral health care. The compelling battery lets you experience its amazingly reliable features for two or more weeks (depends on use).

  • Water-resistant Properties

With the waterproof ProtectiveClean 4100, you can enjoy your enhanced brushing experience even in the shower. Now, this is extra if you want to take a bath and toothbrush to save time.


Unique Features

  • Brush Head Replacement Reminder

Every Sonicare ProtectiveClean toothbrushes manufactured are equipped with a brush head replacement reminder or BrushSync, and 4100 is not an exception. The feature typically commands a higher price, but not in this model. Models aside, the BrushSync reminds you if it is time to replace your brush head after three months or if the quality is worn out. This is great if you want uninterrupted oral health care.


In the official website of Philips Sonicare, you will be surprised how the customer care agents will serve you with pleasure, whether you have something to ask or report. Scroll down below, and you will see "Product support contact options" and choose "Personal Care". Under that, click on "Electric toothbrushes", and Sonicare's customer support will show their contact information. Either you call them through the telephone or have a live conversation with them, it is entirely up to you.

It is also worth noting their self-service tool which fixes warranty and model-related issues. The company also lets you know more about your toothbrush model by typing in the designated model number into the search bar. If you are looking for amazing brush head replacements, their website is also worth stopping by.
