Our Verdict

Philips Sonicare ProtectiveClean 4300 Review 2

The Sonicare ProtectiveClean 4300 is a very good electric toothbrush, featuring Sonciare’s BrushSync reminder technology.

The built-in timer and pacer are welcome inclusions, as are the automatic power off and EasyStart technologies.

Simplicity comes in the form of just 1 cleaning mode, with the option of changing the cleaning intensity. And the battery life is fantastic.

Whilst competitively priced to buy, the higher replacement brush head costs do affect the long term ownership costs.


  • 1 cleaning mode makes it nice & simple to use
  • Timer and pacer encourage brushing for the recommended time
  • Pressure sensor – alerts you when brushing too hard
  • BrushSync technology – reminder when brush heads need replacing
  • Included travel case protects the handle & up to 2 heads
  • Long battery life between charges


Where to buy the Sonicare ProtectiveClean 4300

The Philips ProtectiveClean 4300 can be purchased from a number of different sellers within Singapore. This includes Harvey Norman, Tangs, Gain City, Shopee, Lazada, Philips online store and Best.

Consider these other brushes

If I were buying a brush today, the Oral-B Pro 2 2000 would be my choice.

It’s affordable with the features you need. It is our number 1 choice for the best electric toothbrush.

Choose the 4300 instead, if you are interested in a sonic cleaning action rather than the oscillating-rotating of the Oral-B. Or if you desire a battery life in excess of 2 weeks.

The debate will continue to exist as to whether Sonicare or Oral-B cleans better. Honestly, they are comparable. And all brushes, irrespective of type require you to use the correct technique.

Video Review

The following video is the UK version of the ProtectiveClean 4300. Aside from the price there is no real difference. The general message is the same.

Sonicare ProtectiveClean 4300 in depth review

The name Philips Sonicare is one that is long associated with oral healthcare and for the most part producing excellent toothbrushes.

From an everyday cleaning and usability point of view, the ProtectiveClean 4300 seems to be no exception to this model.

Launched in the Summer of 2018, it offers advances on technology first introduced in 2017, in a more cost effective, lesser featured package.

Variants of this toothbrush

There are 2 different variants of the ProtectiveClean 4300 available in Singapore.

Technically the variants are identical, the difference is the colour of the brush handle, box contents and price.

Each option is assigned a different Sonicare part number too.

Listed below are the different variants of the Sonicare ProtectiveClean 4300.

  • White and light blue – HX6809/16
    • RRP S$149
    • 1 x Brush handle
    • 1 x G2 Optimal Gum Care brush head
    • 1 x White charging stand
  • Light blue and pastel pink – HX6809/36

    • 2 x Brush handle (1 x light blue & 1 x pastel pink)
    • 2 x W2 Optimal White brush head
    • 2 x White charging stand
    • 2 x White travel case
Sonicare ProtectiveClean 4300 Dual Handle

Not all retailers stock each variant.  So, if you have a particular one you want, then you may have to shop around to find it; best to go to Sonicare’s website, and see who is stocking that particular colour option.

What’s in the box

  • 1 x Philips Sonicare ProtectiveClean 4300 electric toothbrush

Key Features

  • Sonic cleaning action – 62,000 movements per minute
  • 1 cleaning mode
  • 2 intensity settings
  • Built-in pressure sensor
  • 2 minute timer and 30 second pacer
  • Automatic power off
  • Brush head reminder system

Design, usability, clean & general use

I want to start this main part of the review off by praising Sonicare on their approach to packaging the 4300.

Compared to previous models, the box is smaller, which means less cardboard use and better from a shelving and transportation perspective.

Both the outer and inner tray are recyclable.

The brush handle, head and charging stand are wrapped in plastic, which is a shame, but they are labelled as recyclable.

It is a small thing, but I feel significant.  Compare this to Oral-B who use a polystyrene inner tray as part of their packaging, in today’s world is this right or required?

Out of the box and in hand the ProtectiveClean 4300 is a lovely solid and premium feeling electric toothbrush.

It is hard to explain, but there is something about the way Sonicare products feel in hand.  There is a certain quality and feeling of ‘premium’ over and above the competition.

In the box you get the brush handle, the brush head, charging stand and the instruction manual.

Sonicare ProtectiveClean 4300 White & Light Blue

The brush is made up of 2 key parts, the handle and the detachable brush head.

The handle is rounded in its shape and has the fairly typical electric toothbrush look to it.

The finish of the plastic has a matt feel rather than the quite common glossy White you see.

Despite the minimal gripping points, it feels like you can hold the brush quite securely.

It would be nice if there were a few strategically placed pieces of rubber to grip onto, but this may detract from the clean design.

The 4300 is available as a single brush in a white and light blue colour.

However, there is a dual handle option whereby you get 1 pastel pink brush handle and 1 light blue brush handle. You also get a travel case for each brush included with that option.

Taking a detailed look at the brush handle then.

Philips Sonicare ProtectiveClean 4300 Review 3

On the front of the handle, at the top, is the Philips Sonicare logo.

Sitting roughly a third of the way down the handle is the round power button. The button itself is concave and makes for a natural place to rest the thumb.  It is made of rubber and has a power symbol embossed on it.

It is around this button that sits the light blue panel which contrasts with the otherwise white handle.

The brush handle is smooth to the touch, and the plastic construction has been coated to give a matt finish, but one that also has the feeling of grip to it.

Unlike some glossy white handles of the past, this does not feel too slippery in hand.

Towards the bottom of the brush handle sits the BrushSync LED and symbol, below this is the battery LED and symbol below that.

Philips Sonicare ProtectiveClean 4300 Review 4

Taking a look at the back of the brush, you would normally expect to find ridges or raised dots to offer up grip, but not here.

The rear of the handle of the 4300 is smooth to the touch, the only exception being a little protrusion just before the bottom of the handle.

Some may wonder what it is.  Well, this very simple notch is ingenious in what it offers.  Should you lay the brush flat on a worktop, this notch stops the brush from rolling, even if knocked.  No more dirty brush bristle. Simple, but effective.

Philips Sonicare ProtectiveClean 4300 Review 5

The base of the brush handle allows for it to stand upright on a flat surface.  But the base does have a recess in it, into which the prong on the charging stand fits.

Moving to the top of the brush handle is where you find the metal shaft that the interchangeable Sonicare brush heads connect to.  This metal shaft feeds into the motor sealed inside the handle.

Brush heads simply push on over this metal shaft and clip in place and pull off with ease.

With a head fitted, when you look side on at the brush handle you will see the head is at a slight angle.  The reason for this is that it helps give a better reach towards the back of the mouth. A subtle but important design feature that enhances the overall usability.

There is only 1 cleaning mode available on the ProtectiveClean 4300.

This Clean mode uses the full power of the internal motor, moving the brush head bristles at up to 31,000 times per minute.

I like the simplicity of just 1 mode.  It suits most users well and does not complicate matters with additional choices that will rarely be used.

As a result of the 1 cleaning mode, there are no LEDs or symbols on the handle to show you which mode is selected.

Nor are there any icons for the brushing intensity that is selected.

Philips Sonicare ProtectiveClean 4300 Review 6

The ProtectiveClean 4300 offers the choice between a high and low intensity, to give you the choice of a softer or more invigorating cleaning experience.

In many respects it is equivalent to having a powerful ‘Clean’ and a ‘Sensitive’ mode on the handle, albeit not labelled as such.

My preference is for the high setting where you get the full power of the motor, but the low setting is certainly more gentle and will appeal to many.

This lower setting is most useful for those with inflamed or sensitive gums.

Pressing the power button turns the brush on, it is then a case of pressing the power button 1 or 2 more times to change the intensity.

It will be obvious, which is which during use.

Press and hold the power button to turn the brush off.  Or alternatively, you can let the brush turn itself off.

One of the extra features it comes with is automatic power off, this happens when the 2 minute cleaning cycle has ended.

2 minutes is the dentist recommended cleaning time.

You need to brush twice a day for 2 minutes.

Philips Sonicare ProtectiveClean 4300 Review 7

Sadly, too few of us brush for this time, so the automatic power off helps encourage us to brush for longer.

But there is another core feature built-in and that is the pacer.

The pacer activates at 30 second intervals, by pausing the brush motor briefly.

This pause alerts you, via the change in brush sound and the lack of movement in the brush head, that it is time to change quadrant.

If you are not familiar with the quadpacing setup built into the 4300, allow me to explain.

Whilst dentists recommend 2 minutes of cleaning twice a day, what this does not help with is ensuring you and I brush our teeth evenly.

The idea is that you break the mouth up into 4 sections.  Upper right, upper left, lower right and lower left.

You spend 30 seconds cleaning each section, that way, over the 120 seconds (2 minutes) of brushing time, you will give a relatively even clean to the teeth and gums.

Philips Sonicare ProtectiveClean 4300 Review 8

The pacer acts as an alert to you, to change quadrant as you brush, to encourage this even clean.

Of course, you don’t have to follow it, but it is good practice.

Do be aware, that there is a particular recommended technique with cleaning the teeth.  The brush head should be held at a 45 degree angle to the teeth.

Offering 31,000 brush strokes (62,000 movements) per minute, the bristles of the brush head move rapidly over the surface of the teeth and gums to dislodge bacteria, plaque and food debris.

Those bristles need only skim the surface of the teeth and this is in part why Sonicare have built a pressure sensor into the brush handle of the ProtectiveClean 4300.

When the brush detects too much force is being applied, the handle vibrates and the brushing sensation changes.

The BrushSync replacement reminder LED flashes Amber when the sensor is activated too.  Given its position and size, it is not the easiest to see.

It is these changes that alert you to the issue.

Relieve the pressure to stop these alerts.

Philips Sonicare ProtectiveClean 4300 Review 9

It does not have the large visible pressure sensor like the light that the Oral-B Pro 2000 and Sonicare’s own DiamondClean Smart offer.

Personally, I do think the light makes it more obvious, particularly when most of us tend to brush in front of a mirror.

Sadly, the flashing amber light on the ProtectiveClean is on the wrong side of the handle for you to really notice,  but you should notice the other changes and reduce the pressure applied, and this will draw your attention to the excess pressure, even if the light does not.

The vibration will kick in every time too much pressure is applied.

Within a few days, you will get used to how much pressure is appropriate.

Brushing too hard long term can potentially damage your teeth and gums. Excess pressure can also wear out the brush heads you use sooner too!

The average life of a brush head is 3 months.  So, every year you should replace your brush head 4 times.

The 1 x G2 optimal gum care brush head that comes supplied in the box with the 4300 lets you know when it needs replacing.

It does this in 2 different ways.

The first is a way that applies to all Sonicare brush heads, fading indicator bristles.

As the head is used, the blue bristles fade to a very pale almost white/translucent colour.  When they are this colour, it is time to change the head.

But a stand out feature of the ProtectiveClean 4300 is the BrushSync replacement reminder system.

Philips Sonicare ProtectiveClean 4300 Review 10

Inside the brush head is a small microchip.

When the brush head is fitted to the brush handle, the chip is detected and the warning light will flash 3 times. This acts as confirmation that the handle has detected the head and that the electronics inside the handle will now keep track of it.

As you use the brush head, the handle continues to track how often it has been used.

The handle knows that the brush head should be replaced every 3 months, so once the handle detects that the brush head has been used for this amount of time, the ‘BrushSync’ LED on the brush handle will light up an amber/orange colour to tell you it is time to change the brush head.

Philips Sonicare ProtectiveClean 4300 Review 11

But, the brush is cleverer still.

If it detects you have brushed 3 times a day every day or brushed with more pressure, it will activate the BrushSync alert system sooner, as the bristles will have worn out sooner than the typical 3 month time period.

By the same token, it will delay alerting you to replace the brush head.  If you used that head just once a day over 3 months, it would not tell you to replace it until it had been used for the equivalent to 4 minutes a day for 3 months.

This is a very neat touch and shows how technology can be used in a positive way to better the nations oral health whilst also being cost effective (by not replacing brush heads too soon).

The G2 optimal gum care brush head is just one of a range of different brush heads available from Sonicare.  Some are BrushSync compatible whilst others are not.

Key differences between them are the length, cut and shape of the bristles to achieve different results.

Some are engineered for plaque removal, whilst others are designed for helping the gums or whitening teeth.

It would be great if a couple of different styles or even another plaque defence head were included in the box.

Philips Sonicare ProtectiveClean 4300 Review 12

The range of heads is confusing.

It is worth knowing that it is perfectly possible to use a non-smart brush head on the 4300 as it is perfectly fine to use a smart brush head on a handle that does not offer BrushSync technology.  But, do be aware, the BrushSync will only work when a compatible head is used on a compatible handle.

Do also note there are ‘premium’ brush sync compatible heads that command a premium of S$15 per head!

You can find out more about the heads and how each one differs by reading our ultimate guide to Sonicare brush heads.

The combination of the Plaque Defence head and the power of the motor built in the 4300 is great.

I have found the clean to be super and after several weeks of testing not felt let down or concerned by the results.  I would have no issue using this on a daily basis or for a prolonged period of time.

Personally, I prefer the smaller round brush heads from Oral-B from a cost and convenience point of view, but I did not struggle too much with the Sonicare heads.

When you might be thinking can the 4300 offer any more, the answer is yes. it does.

Philips Sonicare ProtectiveClean 4300 Review 13

EasyStart is a system that gently increases the power over the first 14 brushings to help you get used to brushing with the Philips Sonicare.

A simple, but innovative touch that shows an extra level of attention and care for first time electric toothbrush users.

If you are not used to the power of an electric toothbrush, the full 62,000 movements per minute can seem quite intense on first use.  EasyStart eases you in.

The dual handle variant come with a travel case for each of the brush handles. That is 2 travel cases. The single handled variant does not.

The plastic case is hinged on the left side with interior moulded mounting points for the handle and up to 2 brush heads.

On the right side is a clip that holds the top and bottom halves of the case together.

Philips Sonicare ProtectiveClean 4300 Review 14

Rounded in the design, it slides into most bags nicely and will protect the heads and handle from damage and accidental activation.

Inside the handle, is the rechargeable Lithium-Ion battery that offers 2 weeks usage between charges or so Sonicare claim.  I managed 5 weeks!

When the power is low, the brush will indicate this through the battery indicator LED.  Just pop it on the provided charging stand for up to 24 hours to fully recharge. You can get more information in the ‘Battery Life’ section of this review.

Philips Sonicare ProtectiveClean 4300 Review 15

Designed to resist water, toothpaste and saliva, the handle of the 4300 is not designed to be used in the shower or the bath.  A quick rinse of the handle is fine, but don’t go immersing it in water.

The handle feels robust and will generally take a few knocks in its life and I have no immediate concerns about the handles reliability.

Sonicare do offer a 2 year warranty that covers any mechanical or workmanship faults, but not user damage.

The design and features definitely beats the older, but cheaper Sonicare 3 Series that is still a cheaper buy at the time of review for not significant sacrifice.

Oral-B’s Pro 2 2000 is the best example of true value for money and it competes well with the 4300.

The Sonicare wins out for the BrushSync technology, design and overall quality but you do pay for this.

The 4300 cleans the teeth well, has all the core features of an electric toothbrush, plus a few more for added benefit.  Sonicare have made a fantastic toothbrush.

Summary of design, usability, clean & general use

  • Slim and comfortable brush handle
  • Sonic cleaning action with up to 62,000 movements per minute
  • 1 cleaning mode
  • 2 brushing intensities
  • 1 brush head included
  • Various styles of brush head available separately
  • Brush head replacement reminder
  • EasyStart programme
  • Built-in timer and 30 second pacer
  • A pressure sensor to stop you brushing too hard
  • 2+ week battery life
  • Water resistant handle
  • 2 year warranty

Battery life

One of the great features of the 4300 is the fact that it comes with a travel case, to protect the brush and make it more convenient to transport it.

Whilst some of us may be on the road or travelling more frequently than others, it is a nice to have as is a battery life that will last the time we are away for.

Most people tend to go away for a night, a long weekend, maybe a week or 2 on holiday.

I am pleased to say that the built-in battery within the ProtectiveClean will last in these instances.

Sonicare ProtectiveClean 4300 Light Blue

Sonicare claim a 14 day battery life from the built-in (non-user removable) lithium-ion battery.

That is a total of 56 minutes usage time, based on 2 cleans per day of 2 minutes in length.

That is 2 weeks or 28 brushing sessions between charges.

The reality is though, that for me in my hands-on testing, I got a lot longer usage time.

From full charge to empty I got just over 5 weeks from the brush!

That is 2.5 times longer than Sonicare suggest.

75 cleaning sessions, on high intensity, each 2 minutes long is what I recorded.

Quite simply brilliant!

I can’t guarantee you will get quite as long, but it is safe to say that 2 weeks will be the absolute minimum you will get from this brush handle.  In reality, you are going to get much longer.

You do get feedback on the battery and the remaining charge via the LED battery/charging icon on the front of the brush handle.

Philips Sonicare ProtectiveClean 4300 Review 16

The way in which it flashes and the colour it is lit tells you how much power is in the Lithium battery.

A solid green LED means a full battery.

A flashing green LED means a medium battery.

A flashing amber LED and three beeps means a low battery.

A flashing amber LED and five beeps means no brushing sessions left, you need to charge the toothbrush.

A charging stand is provided in the box.

Philips Sonicare ProtectiveClean 4300 Review 17

White in colour, the stand allows the brush to sit on top of it.  A prong on the stand fits into the recess on the base of the brush handle.

Wired into it is a power cable with a 2 pin plug. You will need a 2 pin to 3 pin adapter if you do not have one.

Place the handle onto the charging stand and 2 beeps are emitted to let you know that its on charge.

The flashing light of the battery level indicator shows that the toothbrush is charging.  When the handle is fully charged, the battery light shows goes a solid green for 30 seconds and switches off.

It can take up to 24 hours to recharge the battery fully.

A nice touch is that the stand does support voltages of 100-240v.

This ultimately means that should you need to take it with you when you travel, it will work anywhere in the world so long as there is power.  You might just need a plug adapter to ensure it can connect to the power supply in the country you are using it within.

When not in use it is fine to leave the brush on the charging stand being topped up so it is ready for next use.  However, best practice is to keep it off the charging stand (or not have it plugged in) until you need to charge it to achieve maximum life from the battery.

Summary of battery life

  • Lithium-Ion battery technology
  • Sonicare suggest 2 week battery life
  • Achieved 5 weeks usage
  • A solid green LED means a full battery
  • A flashing green LED means a medium battery
  • A flashing amber LED and three beeps means a low battery.
  • A flashing amber LED and five beeps means no brushing sessions left.
  • A charger included in the box
  • Works on 100- 240 volts
  • Takes about 24 hours to charge fully
  • Can be left on the charger

Price & where to buy

I have included links to buying options here at the start of the review.

In the section below, I discuss the price more generally and in relation to similar products.

Things have been very positive for the 4300 and for good reason, Sonicare have done a top job.

And this continues with the price, for the most part at least.

The recommended retail price of this brush is S$149.

Sonicare ProtectiveClean 4300 White & Light Blue In Hand

By no means is this cheap, but it is a little lower than the S$169 of Oral-B’s equivalent.

Thankfully, toothbrushes tend to be subject to a little bit of discount. This is normally around 25%. This therefore makes the typical selling price of the 4300 around S$112.

Whilst this is not always the case, I have seen it lower than this still at around S$90.

This is a big saving and is again more favourable than Oral-B’s Pro 2 2000 that tends to be around S£130.

However, a toothbrush requires replacement heads. Here is where the Philips gets expensive.

A typical Sonicare head works out at S$15 per time.

Compare this to other brands at around S$7 and you can see how any price savings on the handle itself are quickly lost when you factor in the cost of replacement heads.

We like to calculate the cost of ownership over a 3 year period, to give a benchmark comparison cost.

Based on 1 user, you will need a further 11 heads over a 3 year period. At S$15 per time that is an additional cost of $165, on top of the S$112 purchase price.

This gives a total cost of S$277 or $0.25 per day to own.

These prices do exclude the cost of water, toothpaste and electric to charge it, but you get a rough idea.

Philips Sonicare ProtectiveClean 4300 Review 18

Sharing the brush handle, but switching heads with other users in your household will only help bring the cost down and drive more value from it.

As much as I like the 4300, it is slightly disappointing that the heads are that much more expensive.

The Pro 2 2000 from Oral-B works out at $0.20 per day to own. You save S$33 over 3 years by opting with Oral-B over Sonicare.

There is some neat technology in the Philips brush which is worth a premium, if this is what you value.

Please note that all prices quoted are approximates and will vary based on location, supplier and time of purchase.  These figures were correct at the time of writing and should not be relied upon as hard fact, but used as a guide during your decision process.

Summary of price & where to buy

  • Live price comparison of 4300 here
  • Recommended retail price of S$149
  • Actually selling for S$112
  • Brush heads are expensive at S$15 each
  • Works out at around S$0.23 per day over 3 years
  • Oral-B Pro 2 2000 is cheaper

Reliability & long term use

There are many reasons why Sonicare remain as one of the biggest and most trusted brands within the oral healthcare space. Product quality and reliability are just 2 reasons as to why.

The very nature of the product, moving parts and electronic circuits, used in an environment that contains water increases the likelihood of product failure.

However, my own experiences and feedback from site visitors would suggest that they are perhaps the most reliable brand within this space.

The quality of their products is excellent.  The 4300 is no exception.

Materials feel great, the workmanship and fitting of parts are to a very high standard and you can see why Sonicare is often priced at a premium.

Whilst the failure rate is generally very low, should something go wrong then the 4300 is backed by a 2 year manufacturer warranty.

For convenience you can go online and register it after purchase, but should you be in the unfortunate position that it fails during that first 2 years of ownership, contact Sonicare and they will repair or replace it for you.


The ProtectiveClean 4300 is a very good electric toothbrush.

I can praise it on many levels.

Importantly it cleans well, but in today’s world, that is not enough.

The built in timer and pacer are very welcomed as are the automatic power off and EasyStart technologies.

Simplicity comes in the form of just 1 cleaning mode, with the option of changing the cleaning intensity.

The BrushSync replacement reminder is clever and useful and a brilliant example of how technology can be used in simple but effective ways to improve our oral health.

And the battery life is fantastic.

Sadly taking the edge off this, ever so slightly is the cost.

The replacement brush heads are twice the price of the main competing brands which ultimately makes the total ownership cost higher.

Overall there is a lot to like here.  Sonicare have done a top job and I have no issue recommending this brush. But, the Oral-B Pro 2 2000 is comparable and more affordable.
